Question 1

A 34-year-old male is brought to the trauma bay after a motorcycle accident. He is hypotensive (BP 75/40 mmHg) and tachycardic (HR 130). Primary survey reveals an 'open book' pelvic fracture. A pelvic binder is immediately applied to reduce pelvic volume and control hemorrhage. To achieve optimal reduction and biomechanical stability to tamponade bleeding, the binder must be centered over which of the following anatomic landmarks?

Explanation

The correct placement of a pelvic binder is centered over the greater trochanters. Studies have consistently shown that applying the binder at the level of the greater trochanters maximizes the mechanical advantage for closing the pelvic ring (symphysis pubis), thereby reducing pelvic volume and promoting tamponade of venous bleeding. Placement higher over the iliac crests or ASIS is less effective and can paradoxically open the pelvic floor or cause abdominal compression.

Question 2

A 28-year-old male sustains a high-energy Pauwels type III (vertical) femoral neck fracture. Biomechanical studies comparing fixation methods for this specific highly-unstable fracture pattern demonstrate that which of the following constructs provides the greatest resistance to vertical shear forces and subsequent varus collapse?

Explanation

Pauwels type III femoral neck fractures have a fracture angle greater than 50 degrees from the horizontal, subjecting them to high vertical shear forces. Biomechanical evidence shows that a sliding hip screw (SHS) combined with an anti-rotation (derotational) screw provides significantly greater resistance to vertical shear and varus collapse compared to three parallel cancellous screws.

Question 3

A 42-year-old male is undergoing open reduction and internal fixation of a bicondylar tibial plateau fracture (Schatzker VI). The surgeon plans a standard posteromedial approach to directly reduce and buttress a displaced posteromedial fragment. The surgical interval for this approach involves mobilizing and retracting which two structures?

Explanation

The standard posteromedial approach to the proximal tibia exploits the interval between the medial head of the gastrocnemius (which is retracted posteriorly/laterally to protect the neurovascular bundle) and the pes anserinus tendons (which are retracted anteriorly/medially). This provides excellent exposure of the posteromedial tibial plateau.

Question 4

A 30-year-old male sustains a Gustilo-Anderson IIIB open fracture of the middle third of the tibia with a 6 cm anterior soft tissue defect exposing bone void of periosteum. Following thorough serial debridement and skeletal stabilization, which of the following is the most appropriate local muscle flap for coverage of this specific defect?

Explanation

Soft tissue coverage for the tibia is classically divided into thirds. The proximal third is typically covered by a gastrocnemius rotational flap. The middle third is classically covered by a soleus rotational flap. Defects in the distal third of the tibia generally lack adequate local muscle bulk and require free tissue transfer (e.g., gracilis, latissimus dorsi, or ALT flap).

Question 5

A 45-year-old male is involved in a motor vehicle collision and sustains a complex acetabular fracture.

On the obturator oblique radiograph, the 'spur sign' is distinctly visible. According to the Letournel and Judet classification, this radiographic finding is pathognomonic for which of the following acetabular fracture patterns?

Explanation

The 'spur sign' is a pathognomonic radiographic feature of an associated both column acetabular fracture. It is best seen on the obturator oblique view and represents the intact portion of the ilium (the strut attached to the sacroiliac joint) protruding outward as the articular segments (both columns) are medially and internally displaced.

Question 6

A 25-year-old snowboarder sustains a Hawkins type II talar neck fracture and undergoes urgent ORIF. At 8 weeks postoperatively, an AP radiograph of the ankle demonstrates a subchondral radiolucent band in the talar dome, known as the Hawkins sign. What is the clinical significance of this finding?

Explanation

The Hawkins sign is a subchondral radiolucent band seen in the talar dome, typically appearing 6 to 8 weeks after a talar neck fracture. It is a sign of subchondral osteopenia, which can only occur if there is active bone resorption. Active bone resorption requires an intact blood supply; thus, the presence of the Hawkins sign is a reassuring indicator that the talar body retains its vascularity and is unlikely to develop avascular necrosis.

Question 7

A 38-year-old roofer falls from a height and sustains a severely displaced intra-articular calcaneus fracture. The surgeon opts for open reduction and internal fixation utilizing an extensile lateral approach. The full-thickness fasciocutaneous flap elevated in this approach receives its primary blood supply from which of the following vessels?

Explanation

The primary blood supply to the lateral fasciocutaneous flap in an extensile lateral approach to the calcaneus is the lateral calcaneal artery, a terminal branch of the peroneal artery. To preserve this crucial blood supply and prevent flap necrosis, the flap must be elevated in a full-thickness, subperiosteal 'no-touch' fashion.

Question 8

The standard of care for high-energy tibial pilon fractures usually involves temporary application of a spanning external fixator followed by delayed definitive ORIF 10-14 days later. What is the primary rationale for staging the surgical management of this injury?

Explanation

High-energy pilon fractures are associated with severe soft tissue trauma. Early definitive internal fixation through compromised soft tissue carries an unacceptably high risk of wound breakdown, dehiscence, and deep infection. Staged management with a spanning external fixator provides skeletal stability while allowing the soft tissue swelling to subside (the 'wrinkle sign'), significantly lowering complication rates.

Question 9

A 22-year-old male sustains a closed, distal-third spiral humeral shaft fracture (Holstein-Lewis) during an arm-wrestling match. On initial presentation, he exhibits a dense radial nerve palsy. Closed reduction is performed and a coaptation splint is applied. Post-reduction examination confirms the radial nerve palsy is persistent and unchanged. Based on AAOS guidelines, what is the most appropriate management of the radial nerve?

Explanation

For a closed humeral shaft fracture presenting with a primary radial nerve palsy (present before any manipulation), the most appropriate management is observation. Most radial nerve palsies in this setting are neurapraxias that will spontaneously recover within 3-4 months. Immediate exploration is typically reserved for open fractures, penetrating injuries, or secondary palsies (a palsy that develops strictly after closed reduction, indicating potential entrapment).

Question 10

A 55-year-old female undergoes volar locking plate fixation for a displaced intra-articular distal radius fracture. Six months postoperatively, she returns complaining of a sudden inability to actively flex the interphalangeal joint of her thumb. This complication is most closely associated with which of the following surgical technique errors?

Explanation

The inability to actively flex the thumb IP joint indicates a rupture of the flexor pollicis longus (FPL) tendon. In the setting of a prior volar plate for a distal radius fracture, FPL rupture is a known complication associated with plate prominence. When the plate is placed distal to the 'watershed line' (a transverse ridge on the volar distal radius), the prominent distal edge of the hardware causes mechanical attrition and eventual rupture of the FPL tendon.

Question 11

A 20-year-old college athlete falls onto an outstretched hand and sustains a fracture of the proximal pole of the scaphoid. This fracture pattern carries a high risk of nonunion and avascular necrosis due to the scaphoid's retrograde blood supply. Which of the following arteries provides the primary blood supply to the proximal pole of the scaphoid?

Explanation

The scaphoid receives its primary blood supply from the dorsal carpal branch of the radial artery, which enters the scaphoid at the dorsal ridge (distal to the waist) and flows in a retrograde fashion to supply the proximal pole. Consequently, proximal pole fractures disrupt this retrograde blood flow, leading to a high rate of avascular necrosis and nonunion.

Question 12

A 40-year-old male is involved in a high-speed motor vehicle collision. Radiographs and CT scan of his right knee reveal an intra-articular, coronal plane fracture of the lateral femoral condyle. What is the eponym for this specific fracture pattern, and what is the optimal trajectory for lag screw fixation?

Explanation

A Hoffa fracture is a coronal plane fracture of the distal femoral condyle, most commonly affecting the lateral condyle. Because it is a coronal fracture, optimal compression across the fracture site is achieved with lag screws placed perpendicular to the fracture line, typically in an anterior-to-posterior (AP) trajectory.

Question 13

A 28-year-old male sustains a closed comminuted midshaft tibia fracture. Eight hours later, he complains of worsening pain out of proportion to the injury, unrelieved by intravenous opioids. His blood pressure is 110/70 mmHg. Intracompartmental pressure testing of the anterior compartment yields a measurement of 45 mmHg. What is the patient's Delta P (ΔP), and what is the indicated treatment?

Explanation

Acute compartment syndrome is diagnosed clinically, but compartment pressures can be used adjunctively. Delta P (ΔP) is calculated as the diastolic blood pressure minus the compartment pressure (70 - 45 = 25 mmHg). A ΔP of less than 30 mmHg is the accepted threshold indicating inadequate tissue perfusion and is a strict indication for an emergent four-compartment fasciotomy of the leg.

Question 14

The Mangled Extremity Severity Score (MESS) is a clinical tool historically utilized to help guide the difficult decision between amputation and limb salvage in severe lower extremity trauma. Which of the following variables is NOT a scored component of the MESS criteria?

Explanation

The Mangled Extremity Severity Score (MESS) consists of four variables: 1) Skeletal and soft-tissue injury (energy level), 2) Limb ischemia (degree and duration), 3) Shock (systolic blood pressure), and 4) Patient age. The presence of an associated head injury is not a component of the MESS.

Question 15

A 35-year-old male polytrauma patient presents with closed bilateral femoral shaft fractures, multiple rib fractures, and bilateral pulmonary contusions. Initial arterial blood gas evaluation shows a pH of 7.21, base excess of -8, and lactate of 5.0 mmol/L. According to the principles of Damage Control Orthopedics (DCO), what is the most appropriate initial management for his femur fractures?

Explanation

This patient is a 'borderline' or 'unstable' polytrauma patient based on his significant acidosis (pH 7.21), high lactate (5.0 mmol/L), and concomitant chest trauma (pulmonary contusions). Under the principles of Damage Control Orthopedics (DCO), definitive fixation (such as reamed IM nailing) risks a second hit phenomenon, exacerbating ARDS and multisystem organ failure. The optimal management is rapid provisional stabilization with spanning external fixators, delaying definitive nailing until his physiology normalizes.

Question 16

A 45-year-old farmer catches his leg in a tractor mechanism, sustaining a Gustilo-Anderson type IIIA open tibia fracture heavily contaminated with soil and manure. According to current evidence-based guidelines for open fracture management in farm injuries, which of the following intravenous antibiotic regimens is most traditionally appropriate for initial prophylaxis?

Explanation

For severe open fractures (Gustilo Type III), the standard antibiotic regimen historically includes a first-generation cephalosporin (for Gram-positive coverage) and an aminoglycoside (for Gram-negative coverage). If there is gross organic contamination (e.g., farm injury, soil, manure), high-dose penicillin is added specifically to provide coverage against Clostridium species to prevent gas gangrene.

Question 17

A 25-year-old female presents to the trauma bay after a high-speed skiing accident.

Examination reveals a clinically obvious posterior knee dislocation. The joint is urgently reduced in the emergency department. Post-reduction, the extremity is warm, but pulses are slightly asymmetric. An Ankle-Brachial Index (ABI) is calculated to be 0.85. What is the most appropriate next step in management?

Explanation

Knee dislocations carry a high risk of popliteal artery injury. Following reduction, an ABI should be measured. An ABI > 0.9 with symmetrical pulses can typically be observed. However, an ABI < 0.9 indicates impaired distal perfusion and mandates advanced vascular imaging, most commonly a CT angiogram, to rule out an intimal flap or flow-limiting popliteal artery injury.

Question 18

A 32-year-old competitive cyclist falls directly onto his right shoulder, sustaining a midshaft clavicle fracture. Which of the following radiographic or clinical findings is considered an absolute indication for open reduction and internal fixation rather than nonoperative management?

Explanation

Absolute indications for operative fixation of a clavicle fracture include open fractures, fractures with associated neurovascular compromise, and severe skin tenting that threatens skin integrity (impending open fracture). While shortening (>2 cm), complete displacement, and Z-deformities are relative indications (particularly in active patients to prevent nonunion or malunion), an open fracture demands operative debridement and fixation.

Question 19

A 29-year-old football player sustains a hyperplantarflexion injury to his midfoot. Weight-bearing radiographs reveal a 3 mm diastasis between the base of the first and second metatarsals. The primary ligamentous stabilizer disrupted in this injury (the Lisfranc ligament) courses between which two osseous structures?

Explanation

The Lisfranc ligament is the strongest restraint to lateral displacement of the second metatarsal. It originates on the lateral aspect of the medial cuneiform and inserts onto the medial aspect of the base of the second metatarsal. There is no ligamentous connection between the bases of the first and second metatarsals, making the Lisfranc ligament vital for midfoot stability.

Question 20

A 22-year-old male sustains a low-velocity civilian gunshot wound to the right thigh, resulting in a comminuted midshaft femur fracture. The entrance and exit wounds are 1 cm in diameter with no gross contamination or active bleeding. Compartments are soft, and distal pulses are intact. What is the most appropriate management of this injury?

Explanation

Low-velocity gunshot wounds resulting in extra-articular long bone fractures are generally treated as closed fractures with respect to fixation. They do not require formal open debridement of the bullet tract unless there is gross contamination, suspected vascular injury, compartment syndrome, or intra-articular extension. Standard of care includes local wound care, tetanus, short-course IV antibiotics, and early definitive fixation (e.g., IM nailing).

Question 21

A 35-year-old man presents with a posterior hip dislocation and associated posterior wall acetabular fracture after a motor vehicle collision. Closed reduction is performed in the emergency department. The post-reduction CT scan reveals a 40% posterior wall defect with a significant area of marginal impaction. What is the most critical step during open reduction and internal fixation to ensure a congruent joint and minimize post-traumatic arthritis?

Explanation

Marginal impaction must be elevated to restore the articular congruity of the acetabulum. The resulting metaphyseal void must be filled with cancellous bone graft to support the articular surface. Once the articular surface is restored, the posterior wall is reduced and fixed with a buttress plate (often supplemented with spring plates if fragments are small). Failure to elevate marginal impaction leaves a defect in the joint surface, leading to rapid post-traumatic osteoarthritis.

Question 22

A 28-year-old hypotensive male is brought in after a motorcycle crash. A pelvic binder is immediately applied. Radiographs show a widened symphysis pubis and disrupted sacroiliac joints bilaterally, consistent with an Anteroposterior Compression (APC) Type III injury. FAST scan is negative. Despite 2 units of uncrossmatched blood and crystalloid resuscitation, his blood pressure remains 75/40 mmHg. What is the most appropriate next step in management?

Explanation

In a hemodynamically unstable patient with a mechanically unstable pelvic ring injury and no other identified source of major bleeding (negative FAST and chest X-ray), pelvic angiography and embolization is indicated to control arterial hemorrhage. The bleeding is typically from branches of the internal iliac artery, such as the superior gluteal, internal pudendal, or obturator arteries.

Question 23

A 22-year-old male sustains a vertical, displaced basicervical femoral neck fracture (Pauwels Type III) during a sporting event. Which of the following factors has been shown in recent literature to be the most critical in decreasing the rate of nonunion and osteonecrosis in this specific patient population?

Explanation

While historically the timing of surgery (under 6 hours) was considered paramount, recent literature heavily emphasizes that the quality of anatomic reduction is the single most important factor in determining the outcome and decreasing nonunion and AVN rates in young adults with displaced femoral neck fractures. Pauwels III fractures have high shear forces, requiring meticulous reduction and stable fixation (e.g., dynamic hip screw with a derotation screw or proximal femoral locking plate).

Question 24

In the setting of a completely displaced subtrochanteric femur fracture, the proximal fragment is typically displaced into flexion, abduction, and external rotation due to muscular pull. Which muscle group is primarily responsible for the external rotation deformity of the proximal fragment?

Explanation

The short external rotators (piriformis, superior and inferior gemelli, obturator internus and externus, and quadratus femoris) insert on or near the greater trochanter and externally rotate the proximal fragment. The iliopsoas (inserting on the lesser trochanter) causes the flexion deformity. The gluteus medius and minimus (inserting on the greater trochanter) cause the abduction deformity.

Question 25

A 65-year-old woman on long-term alendronate therapy presents with a 3-month history of a dull, aching pain in her right thigh. Radiographs reveal lateral cortical thickening and a transverse radiolucent line in the subtrochanteric region of the right femur.

What is the recommended standard of care for this patient?

Explanation

This patient presents with a symptomatic incomplete atypical femur fracture characterized by the "dreaded black line" (transverse radiolucency) on the tension side of the lateral cortex, associated with long-term bisphosphonate use. Because she has prodromal thigh pain and a visible cortical defect, the fracture is at high risk for completion. Prophylactic intramedullary nailing is the surgical treatment of choice. Medical management includes discontinuing the bisphosphonate and considering teriparatide.

Question 26

A 45-year-old male sustains a high-energy varus injury to his knee, resulting in a medial tibial plateau fracture with a large posteromedial fragment (Schatzker IV). Which of the following surgical approaches is most appropriate for direct visualization and optimal mechanical buttress plating of the posteromedial fragment?

Explanation

The posteromedial fragment in a Schatzker IV tibial plateau fracture is best addressed via a posteromedial approach. The surgical interval is typically developed between the medial head of the gastrocnemius (retracted laterally and posteriorly) and the pes anserinus tendons (retracted medially and anteriorly). This allows for direct visualization of the fracture apex and the placement of an anti-glide or buttress plate to counteract the vertical shear forces.

Question 27

A 30-year-old male is admitted with a closed midshaft tibia fracture treated with casting. Twelve hours later, he complains of severe, escalating leg pain out of proportion to the injury, unrelieved by intravenous opioids. On examination, he has pain with passive stretch of the hallux and a tense calf. When utilizing intra-compartmental pressure monitoring, what is the most definitive diagnostic threshold indicating acute compartment syndrome that requires immediate fasciotomy?

Explanation

Acute compartment syndrome is primarily a clinical diagnosis based on the 'Ps' (pain out of proportion, pain with passive stretch, etc.). However, when pressure measurements are used (e.g., in obtunded or polytrauma patients, or equivocal cases), a Delta pressure (Diastolic Blood Pressure minus Compartment Pressure) of less than 30 mmHg is the most reliable and accepted threshold. Loss of pulses is a very late and unreliable sign.

Question 28

A 42-year-old female presents with a high-energy intra-articular distal tibia fracture (Pilon, AO/OTA 43-C3) with severe soft tissue swelling, fracture blisters, and a significantly shortened extremity. What is the gold standard initial management protocol for this injury?

Explanation

High-energy Pilon fractures are associated with profound soft tissue injury. Early definitive open reduction and internal fixation carries an unacceptably high risk of wound breakdown, deep infection, and osteomyelitis. The standard of care is a two-staged approach: initial application of a joint-spanning external fixator to restore length, alignment, and rotation (Damage Control), followed by definitive ORIF once the soft tissue envelope has healed (typically 10-21 days later, indicated by the 'wrinkle sign' and epithelialization of blisters).

Question 29

During open reduction and internal fixation of a Weber C ankle fracture, the surgeon performs a Cotton test to assess the integrity of the syndesmosis. Which of the following intraoperative radiographic findings during the test indicates dynamic syndesmotic instability requiring fixation?

Explanation

The Cotton test involves placing a bone hook around the fibula and pulling laterally to stress the syndesmosis. Dynamic widening of the medial clear space (typically > 4-5 mm) or the tibiofibular clear space on the mortise view indicates syndesmotic instability. If the medial clear space opens, it indicates that the deltoid ligament is incompetent and the talus is shifting laterally with the fibula, warranting syndesmotic fixation.

Question 30

A 28-year-old male sustains a talar neck fracture following a fall from a height. Radiographs demonstrate a displaced fracture of the talar neck with subluxation of the subtalar joint, but the tibiotalar joint remains congruous. According to the Hawkins classification, what is the fracture type and the historically associated risk of avascular necrosis (AVN) of the talar body?

Explanation

This injury is a Hawkins Type II talar neck fracture, defined by displacement of the talar neck with subluxation or dislocation of the subtalar joint, while the ankle (tibiotalar) joint remains intact. The risk of avascular necrosis (AVN) for Hawkins Type II fractures is widely cited as 20% to 50%. Type I (nondisplaced) is <10%, Type III (subtalar and tibiotalar dislocation) is >90%, and Type IV (Type III plus talonavicular disruption) approaches 100%.

Question 31

In the evaluation and surgical planning of a displaced intra-articular calcaneus fracture, the Sanders classification is highly prognostic. This classification is primarily based on the number of articular fracture lines and their location on which specific imaging view?

Explanation

The Sanders classification is the most widely used system for intra-articular calcaneus fractures. It dictates prognosis and guides treatment. It is based solely on the number and location of primary fracture lines extending through the posterior articular facet, evaluated on the coronal CT image that demonstrates the widest dimension of the posterior facet of the calcaneus.

Question 32

A 24-year-old football player sustains a hyperplantarflexion injury to his midfoot. Radiographs show widening of the space between the base of the first and second metatarsals, indicative of a Lisfranc injury.

The critical Lisfranc ligament, disrupted in this injury, connects which two osseous structures?

Explanation

The Lisfranc ligament is an essential stabilizing structure of the tarsometatarsal joint complex. It is a robust interosseous ligament that runs obliquely from the lateral aspect of the medial cuneiform to the medial aspect of the base of the second metatarsal. There is no direct intermetatarsal ligament connecting the bases of the first and second metatarsals, which creates an inherent area of biomechanical vulnerability.

Question 33

A 45-year-old male sustains an isolated scapula body fracture with involvement of the extra-articular glenoid neck after a high-speed fall. Which of the following radiographic parameters is a generally accepted indication for operative internal fixation of an extra-articular scapular neck fracture?

Explanation

The glenopolar angle (GPA) is a measure of rotational deformity of the glenoid fragment in scapular neck fractures. The normal GPA is 30 to 45 degrees. A GPA of less than 22 degrees signifies severe rotational displacement and is associated with poor functional outcomes (e.g., impingement and altered rotator cuff mechanics), making it a strong indication for operative fixation. Other indications include medial/lateral translation > 20 mm and angular deformity > 45 degrees.

Question 34

A 32-year-old female presents with a closed spiral fracture of the distal third of the humeral shaft resulting from a fall. On physical examination, she is unable to actively extend her wrist or her metacarpophalangeal joints. What is the most appropriate initial management of this injury?

Explanation

A distal third spiral humeral shaft fracture (Holstein-Lewis fracture) is frequently associated with a primary radial nerve palsy. However, in a closed fracture setting, this does not mandate immediate surgical exploration. The radial nerve neuropraxia in this scenario has a spontaneous recovery rate approaching 90%. The standard initial management is conservative fracture care with a coaptation splint or Sarmiento functional bracing, and observation for nerve recovery over 3-6 months. EMG is typically reserved for cases showing no clinical improvement at 6-12 weeks.

Question 35

A 29-year-old female falls onto an outstretched hand and sustains a coronal shear fracture of the capitellum that extends medially to include a large portion of the trochlea (McKee modification of Bryan and Morrey Type IV). What is the optimal surgical approach to address this specific, complex fracture pattern?

Explanation

Coronal shear fractures of the distal humerus involving the capitellum and extending into the trochlea (Type IV) are best visualized and fixed using an extended lateral approach (e.g., utilizing the Kaplan or Kocher interval, extended proximally). This approach allows the anterior capsule to be elevated, providing excellent, direct visualization of the anterior articular surface of the distal humerus. This facilitates the accurate placement of anterior-to-posterior headless compression screws. Posterior approaches, including olecranon osteotomies, provide limited and poor visualization of the anterior coronal articular surface.

Question 36

A 36-year-old male is struck by a heavy metal pipe on the forearm while defending himself. Radiographs reveal a displaced, short oblique fracture of the distal third of the radius with associated widening and disruption of the distal radioulnar joint (DRUJ). This specific injury pattern is best described as a:

Explanation

A Galeazzi fracture is defined as a fracture of the distal third of the radial shaft accompanied by a dislocation or severe subluxation of the distal radioulnar joint (DRUJ). Because of the deforming muscle forces (e.g., brachioradialis, pronator quadratus), it is an inherently unstable "fracture of necessity" in adults, requiring open reduction and internal fixation of the radius followed by intraoperative assessment and stabilization of the DRUJ. A Monteggia fracture involves the proximal third of the ulna with a radial head dislocation.

Question 37

The "terrible triad" of the elbow is a complex instability pattern comprising an elbow dislocation, a radial head fracture, and a coronoid fracture. During open surgical reconstruction of this injury, what is the most widely accepted and biomechanically sound sequence of repair to restore elbow stability?

Explanation

The standard surgical protocol for a terrible triad injury utilizes an 'inside-out' or 'deep-to-superficial' approach. The widely accepted sequence is: 1) Fixation of the coronoid fracture or repair of the anterior capsule to restore the anterior buttress; 2) Repair or replacement of the radial head to restore the lateral column and anterior structural support; and 3) Repair of the lateral collateral ligament (LCL) complex to the lateral epicondyle to restore posterolateral rotatory stability. The Medial Collateral Ligament (MCL) is typically only addressed if the elbow remains grossly unstable after these three steps are completed.

Question 38

A 27-year-old man sustains a severe open tibia fracture following a motorcycle crash. Operative exploration reveals extensive soft tissue stripping, muscle necrosis, and a large segmental soft tissue defect over the anterior leg with exposed, devascularized bone. The vascular surgeon confirms that distal pulses are palpable and major arteries are intact, but the orthopedic and plastic surgeons agree that a free muscle flap will be required for adequate coverage. According to the Gustilo-Anderson classification, what is the grade of this open fracture?

Explanation

A Gustilo-Anderson Type IIIB fracture is defined as a high-energy open fracture with extensive soft-tissue injury, severe periosteal stripping, and bone exposure, which cannot be closed primarily and requires a local rotational or free soft-tissue transfer (flap) for coverage. Type IIIA implies extensive lacerations but adequate local soft tissue to cover the fractured bone without requiring a flap. Type IIIC involves an arterial injury that mandates vascular repair to salvage the limb, regardless of the soft tissue defect size.

Question 39

A 55-year-old female presents with a displaced intra-articular fracture of the distal radius. Radiographs demonstrate a fracture characterized by a volar marginal articular fragment (involving the lunate facet) that has displaced proximally and volarly along with the entire carpus. Which of the following internal fixation constructs is biomechanically optimal to prevent loss of reduction of this specific, highly unstable fragment?

Explanation

This injury describes a volar Barton fracture, which is a volar marginal shear fracture of the distal radius. The volar fragment is pulled proximally by the strong volar radiocarpal ligaments, carrying the carpus with it. This pattern is notoriously unstable. The most biomechanically sound fixation is a volar plate that acts as a physical buttress against the shear forces. Modern volar locking plates, placed as distally as possible (often just proximal to the watershed line) to capture and support the small volar lunate facet fragment, provide the most stable construct to prevent volar subluxation of the carpus.

Question 40

A 34-year-old male is brought to the trauma bay after a severe high-speed motor vehicle collision. He has closed, bilateral comminuted femoral shaft fractures, a grade III spleen laceration, pulmonary contusions, and a moderate traumatic brain injury. His admission labs show a lactate of 5.5 mmol/L, pH of 7.20, and a base excess of -8. Under the principles of Damage Control Orthopedics (DCO), what is the most appropriate initial orthopedic management for his bilateral femur fractures?

Explanation

This polytrauma patient is physiologically unstable (often termed 'borderline' or 'in extremis') as evidenced by severe metabolic acidosis (pH < 7.24, base excess < -5.5), high lactate, and concurrent major torso and brain injuries. He is a poor candidate for Early Total Care (ETC) with intramedullary nailing, as the prolonged surgery, blood loss, and medullary canal pressurization can cause a 'second hit' phenomenon, exacerbating ARDS, coagulopathy, and secondary brain injury. Damage Control Orthopedics (DCO) dictates the rapid, temporary stabilization of major long bone fractures with external fixators to mitigate ongoing hemorrhage and systemic inflammatory response, allowing the patient to be resuscitated in the ICU.

Question 41

A 35-year-old male sustains a high-energy trauma resulting in a distal femur fracture. CT scan reveals a coronal plane fracture of the lateral femoral condyle. Which of the following is the most appropriate surgical approach and fixation strategy for this specific fracture pattern?

Explanation

A coronal plane fracture of the femoral condyle is known as a Hoffa fracture. It most commonly affects the lateral condyle. The standard treatment is anatomic reduction and rigid internal fixation, typically achieved via a lateral approach. Interfragmentary lag screws are usually placed from anterior to posterior to compress the fragment, as this avoids the articular surface of the posterior condyle.

Question 42

A 45-year-old man presents with a subtrochanteric femoral fracture. The proximal fragment is typically flexed, abducted, and externally rotated. Which muscle group is primarily responsible for the external rotation of the proximal fragment?

Explanation

In a subtrochanteric fracture, the proximal fragment is acted upon by several deforming forces: it is flexed by the iliopsoas, abducted by the gluteus medius and minimus, and externally rotated by the short external rotators (piriformis, superior/inferior gemelli, obturator internus/externus, and quadratus femoris). The distal fragment is pulled proximally and medially by the adductors.

Question 43

A 28-year-old female is brought to the ED after a motor vehicle collision. She is hemodynamically unstable. A pelvic binder is applied.

Radiographs show a widened symphysis pubis > 2.5 cm and disruption of the anterior sacroiliac ligaments, but intact posterior sacroiliac ligaments. According to the Young-Burgess classification, what type of injury is this, and what is the most common primary source of bleeding?

Explanation

Anterior Posterior Compression (APC) II injuries involve symphyseal widening > 2.5 cm with disruption of the anterior SI ligaments, sacrotuberous, and sacrospinous ligaments, but the posterior SI ligaments remain intact, providing vertical stability but rotational instability. The primary source of life-threatening hemorrhage in pelvic fractures, especially open book types, is the presacral venous plexus, though arterial bleeding can also occur.

Question 44

A 32-year-old man sustained a talar neck fracture 8 weeks ago. He is being followed up in the clinic. Radiographs reveal a subchondral radiolucent band in the dome of the talus. What does this finding (Hawkins sign) indicate?

Explanation

The Hawkins sign is a subchondral radiolucent band seen in the talar dome on an AP or mortise radiograph 6 to 8 weeks post-injury. It indicates subchondral atrophy due to hyperemia, confirming that the talar body has an intact blood supply and that avascular necrosis (AVN) is highly unlikely.

Question 45

A 24-year-old male sustains a closed tibial shaft fracture. Two hours post-admission, he complains of severe pain out of proportion to the injury. On examination, pain is exacerbated by passive stretch of the toes. Intracompartmental pressure testing is performed. Which of the following pressure readings is the most widely accepted absolute indication for a four-compartment fasciotomy?

Explanation

The most reliable and widely accepted parameter for diagnosing acute compartment syndrome and indicating the need for fasciotomy is a Delta P < 30 mmHg. Delta P is calculated as the patient's diastolic blood pressure minus the measured intracompartmental pressure. Relying on an absolute pressure value can lead to unnecessary fasciotomies in hypotensive patients or missed diagnoses in hypertensive patients.

Question 46

A 30-year-old male presents with a closed, isolated spiral fracture of the distal third of the humeral shaft (Holstein-Lewis fracture). On examination, he is unable to extend his wrist or fingers. What is the most appropriate initial management for the nerve injury?

Explanation

A primary radial nerve palsy in the setting of a closed humeral shaft fracture (including Holstein-Lewis fractures) is generally a neuropraxia. The most appropriate initial management is conservative treatment of the fracture (e.g., coaptation splint followed by functional bracing) and observation of the nerve function. Nerve recovery is typically seen within 3 to 4 months. If no clinical or EMG signs of recovery are present by 3-4 months, surgical exploration is indicated.

Question 47

A 42-year-old female pedestrian is struck by a car. Radiographs of her knee show a split-depression fracture of the lateral tibial plateau. According to the Schatzker classification, what is the type of this fracture?

Explanation

The Schatzker classification organizes tibial plateau fractures. Type I is a pure split of the lateral plateau (typically seen in younger patients with strong cancellous bone). Type II is a split-depression fracture of the lateral plateau. Type III is a pure central depression of the lateral plateau (typically seen in older, osteoporotic patients). Type IV involves the medial plateau. Type V is a bicondylar fracture. Type VI includes metaphyseal-diaphyseal dissociation.

Question 48

A 40-year-old roofer falls from a height and sustains a closed, displaced intra-articular calcaneus fracture. Surgery is planned using an extensile lateral approach. Which of the following nerves is at greatest risk of iatrogenic injury during this specific surgical approach?

Explanation

The extensile lateral approach to the calcaneus involves creating a full-thickness "no-touch" subperiosteal flap. The sural nerve crosses the lateral border of the foot and is incorporated into the flap. It is at significant risk of injury either from the initial incision or from traction/retraction during the procedure.

Question 49

A 50-year-old man is involved in a high-speed MVC. AP pelvis and Judet views show an acetabular fracture.

The obturator oblique view shows disruption of the iliopectineal line, and the iliac oblique view shows an intact ilioischial line. Which of the following fracture patterns is most consistent with these radiographic findings?

Explanation

In the Judet radiographic evaluation of the acetabulum, the obturator oblique view highlights the anterior column (iliopectineal line) and the posterior wall. The iliac oblique view highlights the posterior column (ilioischial line) and the anterior wall. Disruption of the iliopectineal line with an intact ilioischial line indicates an isolated anterior column fracture.

Question 50

A 35-year-old female falls on an outstretched hand and presents with elbow pain and instability. Radiographs confirm an elbow dislocation, radial head fracture, and coronoid fracture. Which of the following is the most appropriate sequence of surgical reconstruction for this 'terrible triad' injury?

Explanation

The standard surgical sequence for a terrible triad injury of the elbow follows a deep-to-superficial (inside-out) approach: 1) Fixation of the coronoid fracture to restore the anterior buttress, 2) Fixation or replacement of the radial head to restore the lateral column, and 3) Repair of the lateral collateral ligament (LCL) complex to the lateral epicondyle. MCL repair or hinged external fixation is reserved for cases where the elbow remains unstable after these steps.

Question 51

A 28-year-old male motorcyclist sustains an open midshaft tibial fracture. The wound is 12 cm long with extensive soft tissue stripping and visible muscle necrosis, but there is adequate periosteal coverage and the soft tissue can be approximated without a flap. According to the Gustilo-Anderson classification, what is the grade of this open fracture?

Explanation

Gustilo-Anderson Grade IIIA involves a high-energy trauma with extensive soft-tissue laceration (typically >10 cm) and adequate bone coverage. Despite the extensive soft tissue damage, stripping, and high energy mechanism, the key distinguishing factor from Grade IIIB is that there is adequate periosteal coverage, and local or free flaps are not required for wound closure.

Question 52

A 22-year-old man falls on an outstretched hand. He has anatomic snuffbox tenderness. Radiographs show a fracture through the proximal pole of the scaphoid. This fracture is at high risk of avascular necrosis (AVN). Which of the following best describes the primary blood supply to the scaphoid?

Explanation

The primary blood supply to the scaphoid (approx. 70-80%) comes from the dorsal carpal branch of the radial artery, which enters the bone at the dorsal ridge near the distal pole and waist. This vascular network flows in a retrograde fashion to supply the proximal pole. Thus, fractures at the waist or proximal pole disrupt this supply, putting the proximal pole at a high risk for AVN and nonunion.

Question 53

A 45-year-old male falls from a ladder and sustains a high-energy tibial pilon fracture with severe soft tissue swelling and fracture blisters. What is the most appropriate initial management?

Explanation

High-energy pilon fractures are associated with significant soft tissue compromise. Immediate ORIF carries a very high risk of wound breakdown and deep infection. The standard of care is a staged approach: initial application of a spanning external fixator (with or without fibular fixation) to restore length and alignment while allowing the soft tissues to recover, followed by definitive ORIF once the soft tissue envelope permits (e.g., wrinkle sign present), usually at 10-21 days.

Question 54

A 6-year-old boy falls off monkey bars. Radiographs show a fracture of the proximal third of the ulna with an associated dislocation of the radial head. According to the Bado classification, what is the most common type of Monteggia fracture-dislocation?

Explanation

Bado Type I is the most common type of Monteggia fracture-dislocation, accounting for approximately 60% of cases. It is characterized by an anterior dislocation of the radial head and a fracture of the ulnar diaphysis with anterior apex angulation. Bado II is posterior, Bado III is lateral, and Bado IV involves fractures of both forearm bones.

Question 55

A 72-year-old female presents with a 4-part proximal humerus fracture after a fall.

Which of the following factors most significantly increases the risk of avascular necrosis (AVN) of the humeral head in this setting?

Explanation

Hertel described radiographic predictors of ischemia (and potential AVN) in proximal humerus fractures. The most significant predictors include an anatomic neck fracture pattern, a short medial calcar segment (< 8 mm) attached to the articular segment, and disruption of the medial hinge. While historically the anterior humeral circumflex artery was thought to be the main supply, recent studies show the posterior humeral circumflex artery is the primary blood supply; regardless, Hertel's radiographic criteria remain standard for predicting AVN.

Question 56

A 68-year-old female with a 10-year history of alendronate use presents with sudden, atraumatic thigh pain. Radiographs reveal a transverse fracture of the lateral cortex of the subtrochanteric femur with a focal periosteal reaction ('beaking'). What is the pathophysiological mechanism behind this fracture?

Explanation

Long-term use of bisphosphonates (typically > 5 years) suppresses osteoclast-mediated bone remodeling. This severe suppression prevents the repair of normal physiological microdamage in the bone, leading to accumulation of microcracks and increased brittleness. This mechanism is responsible for bisphosphonate-related atypical femoral fractures, which characteristically present with lateral cortical thickening, 'beaking', and a transverse or short oblique fracture pattern.

Question 57

A 25-year-old football player sustains a forced plantar flexion injury to his midfoot. He has plantar ecchymosis and pain over the tarsometatarsal joints. Weight-bearing radiographs show 3 mm of widening between the bases of the 1st and 2nd metatarsals. Which ligament is primarily injured, and what structures does it connect?

Explanation

The Lisfranc ligament is a strong interosseous ligament that connects the medial cuneiform to the base of the 2nd metatarsal. It is critical for the stability of the midfoot because there is no direct intermetatarsal ligament between the 1st and 2nd metatarsal bases. Disruption of this ligament leads to widening of the interval, a hallmark of a Lisfranc injury. Plantar ecchymosis is a highly specific clinical sign.

Question 58

A 30-year-old male sustains a femoral neck fracture in a high-speed MVC. The fracture is oriented nearly vertically (Pauwels Type III, 70 degrees). Which of the following biomechanical forces predominates at the fracture site, making internal fixation challenging?

Explanation

The Pauwels classification of femoral neck fractures is based on the angle of the fracture line relative to the horizontal. Type I is < 30 degrees, Type II is 30-50 degrees, and Type III is > 50 degrees. As the angle increases (more vertical fracture line), the biomechanical forces at the fracture site shift from predominantly compressive (which are favorable for healing) to primarily shear forces, which promote displacement, varus collapse, and nonunion, making stable internal fixation challenging.

Question 59

A 55-year-old female presents with a wrist injury after a fall. Radiographs show a fracture of the distal radius with a displaced volar articular lip and volar subluxation of the carpus. Which of the following is the most accurate diagnosis and recommended treatment?

Explanation

A volar Barton fracture is a shear-type intra-articular fracture of the distal radius with displacement of the volar articular margin and concomitant volar subluxation of the carpus. Because it is highly unstable and involves the articular surface, the standard of care is open reduction and internal fixation, typically utilizing a volar buttress plate to counteract the shear forces.

Question 60

A 24-year-old male cyclist falls and sustains a midshaft clavicle fracture. Which of the following is an absolute indication for immediate operative management (ORIF) of this fracture?

Explanation

Absolute indications for surgical fixation of a clavicle fracture include an open fracture, an associated neurovascular injury, skin tenting that threatens to progress to an open fracture (impending open), and a floating shoulder (clavicle fracture combined with an unstable scapular neck fracture). While displacement and shortening > 2 cm are strong relative indications in active adults to prevent nonunion and shoulder dysfunction, an open fracture represents a surgical emergency and is an absolute indication.

Question 61

The Lower Extremity Assessment Project (LEAP) evaluated outcomes following severe lower extremity trauma resulting in a mangled limb. Which of the following statements most accurately reflects the findings of this multicenter study?

Explanation

The LEAP study demonstrated that at 2 years, there was no significant difference in functional outcomes between limb salvage and early amputation. It also found that the MESS score does not accurately predict successful limb salvage.

Question 62

A 28-year-old male sustains a Hawkins Type III fracture of the talar neck. At 8 weeks post-operative follow-up, an AP radiograph of the ankle reveals a subchondral radiolucent band across the talar dome (Hawkins sign). What does this radiographic finding indicate?

Explanation

The Hawkins sign represents subchondral osteopenia, which requires an intact blood supply to resorb bone. Its presence indicates intact vascularity and heavily rules out avascular necrosis.

Question 63

In a polytraumatized patient presenting with a closed femoral shaft fracture, which of the following is considered an absolute indication for Damage Control Orthopedics (DCO) using external fixation rather than Early Total Care (ETC) with intramedullary nailing?

Explanation

A PaO2/FiO2 ratio < 200 mmHg defines acute respiratory distress syndrome (ARDS) and profound physiologic instability. In such borderline or unstable patients, DCO minimizes the second hit of systemic inflammation associated with reaming and nailing.

Question 64

A 65-year-old female presents with the inability to actively flex her thumb interphalangeal joint 6 months after open reduction and internal fixation of a distal radius fracture with a volar locking plate. What is the most likely etiology of her new deficit?

Explanation

FPL rupture is a known complication of volar plating of the distal radius, typically occurring when the plate is placed distal to the watershed line, causing mechanical attrition of the tendon.

Question 65

During an extensile lateral approach for the fixation of a displaced intra-articular calcaneus fracture, the surgeon elevates a full-thickness subperiosteal flap.

To prevent wound edge necrosis, this flap relies primarily on blood supply from which of the following vessels?

Explanation

The lateral calcaneal artery, a branch of the peroneal artery, provides the primary vascular supply to the lateral soft tissues of the heel. A full-thickness subperiosteal "no-touch" flap preserves this critical angiosome.

Question 66

A 30-year-old male is undergoing open reduction of a posterior wall acetabular fracture via a Kocher-Langenbeck approach. The surgeon limits splitting of the gluteus maximus and avoids dissecting more than 5 cm proximal to the greater sciatic notch. This maneuver is specifically performed to protect which of the following nerves?

Explanation

The superior gluteal nerve exits the greater sciatic notch superior to the piriformis and supplies the abductor musculature. Dissection >5 cm above the notch during the Kocher-Langenbeck approach places this nerve at high risk of iatrogenic injury.

Question 67

A 22-year-old male presents with a comminuted midshaft tibia fracture and pain out of proportion to the injury. His blood pressure is 110/70 mmHg. Intracompartmental pressure measurements of the lower leg are obtained. What pressure threshold indicates the need for emergent four-compartment fasciotomies?

Explanation

A delta pressure (diastolic blood pressure minus intracompartmental pressure) of less than 30 mmHg is the accepted threshold for diagnosing acute compartment syndrome and mandates emergent fasciotomy.

Question 68

A 45-year-old male sustains an acetabular fracture after a motor vehicle collision. AP and Judet views show disruption of the iliopectineal line with an intact ilioischial line. Which of the following best describes this fracture pattern?

Explanation

Disruption of the iliopectineal line indicates an anterior column or anterior wall fracture. The ilioischial line represents the posterior column, which is intact in this isolated anterior injury.

Question 69

A 25-year-old polytrauma patient with bilateral femoral shaft fractures and a severe pulmonary contusion is evaluated for definitive fracture fixation versus damage control orthopedics (DCO). Which of the following physiological parameters is the most reliable indicator of adequate resuscitation for safe early total care?

Explanation

Serum lactate clearance (< 2.5 mmol/L) and correction of base deficit are the most sensitive and reliable markers of adequate tissue perfusion and resuscitation. Early total care in under-resuscitated polytrauma patients drastically increases the risk of ARDS.

Question 70

A 30-year-old male falls from a height and sustains a Hawkins Type III talar neck fracture. Which of the following best describes the disruption of blood supply leading to the near 100% rate of avascular necrosis in this specific fracture pattern?

Explanation

A Hawkins Type III fracture is a talar neck fracture with both subtalar and tibiotalar dislocation. This severe displacement tears all three major blood supplies to the talar body, leading to a profound risk of avascular necrosis.

Question 71

A 22-year-old male presents with a closed distal-third spiral humeral shaft fracture (Holstein-Lewis) following an arm-wrestling match. On examination, he has an absent brachioradialis reflex and inability to extend his wrist. What is the most appropriate initial management?

Explanation

Primary radial nerve palsy in the setting of a closed humeral shaft fracture is managed non-operatively with a coaptation splint and observation. Spontaneous nerve recovery occurs in up to 90% of cases within 3 to 4 months.

Question 72

A 40-year-old farmer sustains an open tibial shaft fracture with massive soft tissue stripping and gross soil contamination after his leg is caught in a tractor. According to the updated guidelines for severe agricultural open fractures, which empiric antibiotic regimen should be initiated immediately?

Explanation

For severe agricultural injuries with gross soil contamination (Gustilo IIIB/C), high-dose penicillin is added to a standard regimen (first-generation cephalosporin and an aminoglycoside). This provides specific coverage against Clostridium species to prevent gas gangrene.

Question 73

A 28-year-old male with a closed tibial shaft fracture reports severe, unrelenting leg pain out of proportion to his injury. His blood pressure is 110/70 mmHg. Which of the following intracompartmental pressure readings is an absolute indication for emergency four-compartment fasciotomy?

Explanation

A delta pressure (diastolic blood pressure minus intracompartmental pressure) of less than 30 mmHg is the most reliable threshold for diagnosing acute compartment syndrome. A delta pressure of 20 mmHg indicates profound ischemia mandating emergent fasciotomy.

Question 74

A hemodynamically unstable 35-year-old male with an APC-III pelvic ring injury remains hypotensive (BP 70/40 mmHg) despite pelvic binder application, activation of a massive transfusion protocol, and a negative FAST exam. What is the most appropriate next step in acute management?

Explanation

In a hemodynamically unstable pelvic fracture with a negative FAST (ruling out major intra-abdominal hemorrhage), the bleeding is presumed pelvic. Immediate preperitoneal packing or angiography with embolization is indicated to control retroperitoneal hemorrhage.
