Question 9501

Topic: 2. Trauma

A 40-year-old male with a Gustilo-Anderson Type II open mid-shaft femoral fracture is undergoing reamed intramedullary nailing. What is the most important factor in reducing the risk of deep infection in this specific scenario?

. A. Administration of prophylactic antibiotics within 1 hour of injury.
. B. Thorough debridement and copious irrigation of the wound.
. C. Primary wound closure at the time of nailing.
. D. Application of a vacuum-assisted closure device post-operatively.
. E. Post-operative intravenous antibiotics for 6 weeks.

Correct Answer & Explanation

. B. Thorough debridement and copious irrigation of the wound.


Explanation

For open fractures, thorough debridement of all devitalized tissue and copious irrigation (B) is the single most critical step in reducing the bacterial load and preventing deep infection. While early prophylactic antibiotics (A) are also crucial, the surgical removal of contaminated and necrotic tissue cannot be overstated. Primary wound closure (C) is often avoided in open fractures, favoring delayed closure. VAC (D) can assist with wound management but is not primary prevention. Extended IV antibiotics (E) are usually for established infection, not prophylaxis.

Question 9502

Topic: 2. Trauma

When performing intramedullary nailing of a subtrochanteric femoral fracture, what is the purpose of placing the patient in a Trendelenburg position?

. A. To improve venous return and reduce blood loss.
. B. To facilitate reduction by allowing gravity to reduce the proximal fragment's abduction.
. C. To prevent fat embolism syndrome.
. D. To improve fluoroscopic visualization of the distal locking screws.
. E. To decrease intra-abdominal pressure during surgery.

Correct Answer & Explanation

. B. To facilitate reduction by allowing gravity to reduce the proximal fragment's abduction.


Explanation

In subtrochanteric femoral fractures, the strong pull of the gluteus medius and minimus muscles causes the proximal fragment to abduct. Placing the patient in a Trendelenburg position allows gravity to assist in reducing this abduction, making it easier to align the proximal fragment with the distal shaft and insert the intramedullary nail. While it can have effects on venous return (A), the primary orthopedic rationale is for reduction assistance.

Question 9503

Topic: 2. Trauma

A patient undergoes antegrade intramedullary nailing for a comminuted distal third femoral shaft fracture. Post-operatively, the patient develops a persistent malreduction with apex anterior angulation. What is the most likely intraoperative technical error that contributed to this malunion?

. A. Insufficient reaming of the medullary canal.
. B. Inadequate length of the intramedullary nail.
. C. Failure to maintain reduction during proximal locking.
. D. Incorrect starting point for nail insertion, typically too anterior.
. E. Placing the distal locking screws before achieving anatomical alignment.

Correct Answer & Explanation

. D. Incorrect starting point for nail insertion, typically too anterior.


Explanation

An apex anterior angulation (procurvatum) malunion in femoral nailing, especially in the distal third, is commonly caused by an incorrect starting point for nail insertion that is too anterior on the greater trochanter or piriformis fossa. This anterior entry point forces the nail to impinge on the posterior cortex of the femoral shaft, leading to an apex anterior angulation. Insufficient reaming (A) might cause difficulty inserting the nail but not typically this specific malunion. Inadequate nail length (B) or locking errors (C, E) can cause shortening or rotational malunion, but an anterior starting point is a classic cause of apex anterior angulation.

Question 9504

Topic: 2. Trauma

What is the primary purpose of a fracture table with traction for femoral shaft intramedullary nailing?

. A. To provide continuous intraoperative monitoring of nerve function.
. B. To assist in reducing the fracture and maintaining length.
. C. To facilitate sterile draping of the operative field.
. D. To reduce the risk of deep vein thrombosis.
. E. To allow for easier patient transfer post-operatively.

Correct Answer & Explanation

. B. To assist in reducing the fracture and maintaining length.


Explanation

A fracture table with traction is primarily used to assist in reducing the fracture (by overcoming muscle spasm and distracting fragments) and maintaining appropriate length and alignment during the intramedullary nailing procedure for femoral shaft fractures. This provides a stable platform for the surgeon to work. It does not primarily monitor nerve function (A), facilitate draping (C), reduce DVT risk (D), or ease transfer (E).

Question 9505

Topic: 2. Trauma

Which of the following describes a key advantage of an antegrade humeral intramedullary nail over a retrograde humeral nail?

. A. Lower risk of shoulder impingement.
. B. Easier entry point visualization.
. C. Better stability for distal third humeral fractures.
. D. Does not violate the shoulder joint capsule.
. E. Reduced risk of iatrogenic radial nerve injury.

Correct Answer & Explanation

. E. Reduced risk of iatrogenic radial nerve injury.


Explanation

Compared to retrograde nailing, antegrade humeral nailing typically has a reduced risk of iatrogenic radial nerve injury (E). The retrograde approach often involves more manipulation of the distal fragment, and the distal locking screws are closer to the radial nerve in the distal humerus, increasing the risk. Antegrade nailing, however, carries a higher risk of shoulder impingement (A) due to the entry portal. Entry point visualization (B) is generally good for both. Retrograde is often preferred for distal fractures (C). Antegrade does violate the shoulder capsule (D) at its entry point.

Question 9506

Topic: 2. Trauma

A 50-year-old male is undergoing reamed intramedullary nailing for a mid-diaphyseal tibial fracture. Which parameter is most important to monitor and prevent during the reaming process to avoid thermal necrosis of the bone?

. A. Intramedullary pressure.
. B. Reamer size progression.
. C. Reaming speed and irrigation.
. D. Patient's core body temperature.
. E. Fracture reduction quality.

Correct Answer & Explanation

. C. Reaming speed and irrigation.


Explanation

Thermal necrosis of the bone during reaming is a recognized concern. It is best prevented by careful control of the reaming speed (avoiding rapid, prolonged reaming) and ensuring adequate irrigation (C) to dissipate heat generated by the reamer-bone interface. While intramedullary pressure (A) is a concern for fat embolism, and reamer size (B) progression is important for nail fit, these are not directly related to thermal necrosis prevention. Core body temperature (D) is a systemic parameter, and reduction quality (E) is a separate surgical goal.

Question 9507

Topic: 2. Trauma

What is the main advantage of using a dynamic locking option in an intramedullary nail for a simple transverse tibial shaft fracture that shows signs of delayed union?

. A. It provides absolute rotational stability.
. B. It increases the bending stiffness of the construct.
. C. It allows for controlled axial micromotion, which can stimulate callus formation.
. D. It eliminates the need for bone grafting.
. E. It prevents nonunion in all cases.

Correct Answer & Explanation

. C. It allows for controlled axial micromotion, which can stimulate callus formation.


Explanation

For a simple transverse tibial shaft fracture with delayed union, converting to a dynamic locking option (e.g., by removing one locking screw to allow movement in a slotted hole) can be beneficial. This allows for controlled axial micromotion (C) at the fracture site, which provides a biomechanical stimulus for callus formation and bone healing, often promoting progression from delayed union to union. It does not provide absolute rotational stability (A) or increased bending stiffness (B) compared to static locking. It doesn't eliminate the need for grafting (D) if biology is poor, nor does it guarantee union (E).

Question 9508

Topic: 2. Trauma

A 25-year-old male sustains a closed comminuted mid-shaft femoral fracture. What specific anatomical feature of the femur guides the decision for the appropriate length of the intramedullary nail?

. A. The distance from the greater trochanter to the medial femoral condyle.
. B. The distance from the greater trochanter to the lateral femoral condyle.
. C. The distance from the femoral head to the adductor tubercle.
. D. The distance from the greater trochanter to the intercondylar notch.
. E. The distance from the lesser trochanter to the epicondylar axis.

Correct Answer & Explanation

. D. The distance from the greater trochanter to the intercondylar notch.


Explanation

The appropriate length of an antegrade femoral intramedullary nail is typically determined by measuring the distance from the tip of the greater trochanter to the intercondylar notch (D) on a contralateral, uninjured femur or using a full-length AP radiograph of the injured femur. The goal is for the nail to terminate just proximal to the intercondylar notch, usually 1-2 cm above it, to avoid damaging the articular cartilage or ligaments of the knee joint. Medial (A) or lateral (B) condyle measurements are less precise due to curvature. Other options (C, E) are not standard measurements for nail length.

Question 9509

Topic: 2. Trauma

In the setting of intramedullary nailing for a tibial shaft fracture, what is the significance of the 'fibula length' or 'fibula intact' concept?

. A. It dictates the choice between a reamed or unreamed nail.
. B. It influences the risk of compartment syndrome post-operatively.
. C. An intact fibula can contribute to malreduction (e.g., shortening, angulation) of the tibial fracture.
. D. An intact fibula significantly increases the risk of nonunion.
. E. It requires prophylactic fibular osteotomy in all cases.

Correct Answer & Explanation

. C. An intact fibula can contribute to malreduction (e.g., shortening, angulation) of the tibial fracture.


Explanation

An intact fibula, particularly in fractures of the distal or proximal tibia, can act as a 'splint' or 'tether.' This can prevent proper reduction of the tibial fracture, leading to persistent shortening, angulation, or translation (malreduction). The fibula maintains its length, while the comminuted or shortened tibia struggles to achieve its anatomical length against this intact fibular splint. In such cases, a fibular osteotomy or resection may be considered to facilitate tibial reduction. It does not dictate nail type (A), affect compartment syndrome (B) directly, or increase nonunion risk (D) beyond its impact on reduction. Prophylactic osteotomy (E) is not always required.

Question 9510

Topic: 2. Trauma

Which factor is most crucial in achieving a successful union following intramedullary nailing of an atrophic tibial nonunion?

. A. Conversion from static to dynamic locking.
. B. Over-reaming the medullary canal by 2mm.
. C. Application of bone graft in conjunction with stable fixation.
. D. Early weight-bearing to promote callus formation.
. E. Administration of anti-inflammatory drugs to reduce pain.

Correct Answer & Explanation

. C. Application of bone graft in conjunction with stable fixation.


Explanation

Atrophic nonunions are characterized by a lack of biological healing potential. Therefore, successful union requires not only stable mechanical fixation (which exchange nailing can provide) but critically, the addition of biological stimulation, typically achieved through bone grafting (C). While over-reaming (B) can stimulate biology and conversion to dynamic locking (A) can help, they are usually insufficient for true atrophic nonunions without additional graft. Early weight-bearing (D) is beneficial for healing but relies on underlying biological potential. Anti-inflammatory drugs (E) can inhibit healing.

Question 9511

Topic: 2. Trauma

A 30-year-old patient presents with a mid-shaft femoral fracture. During intramedullary nailing, what is the most reliable intraoperative fluoroscopic view to assess the rotational alignment of the fracture?

. A. Anteroposterior (AP) view of the hip.
. B. Lateral view of the knee.
. C. Comparison of the lesser trochanter profile on AP hip views.
. D. Comparison of the cortical step sign on true lateral views of the fracture site.
. E. AP view of the foot to assess rotation.

Correct Answer & Explanation

. C. Comparison of the lesser trochanter profile on AP hip views.


Explanation

While there are multiple techniques, the most reliable intraoperative fluoroscopic method to assess rotational alignment of the femoral shaft is often considered the comparison of the lesser trochanter profile on AP hip views (C). The lesser trochanter should appear minimally visible or not at all (e.g., 'zero rotation' profile) on the uninjured side, and this should be matched on the injured side. Alternatively, a 'cortical step sign' on true lateral views of the proximal and distal fragments (D) can be used. Foot rotation (E) is often used clinically but can be unreliable due to ankle/foot positioning. AP hip (A) and lateral knee (B) views are important but less specific for rotation.

Question 9512

Topic: 2. Trauma
In the management of a Gustilo-Anderson Type IIIA open tibial shaft fracture treated with intramedullary nailing, when is reaming generally considered acceptable?
. Only if the wound is less than 2 cm.
. Immediately at the time of initial debridement.
. After thorough debridement, copious irrigation, and when soft tissues appear viable and non-infected.
. Never, due to the high risk of infection.
. Only if a vacuum-assisted closure (VAC) device has been in place for at least 48 hours.

Correct Answer & Explanation

. After thorough debridement, copious irrigation, and when soft tissues appear viable and non-infected.


Explanation

For Gustilo-Anderson Type IIIA open tibial shaft fractures, reamed intramedullary nailing can be performed, but only after thorough debridement and copious irrigation, and when the soft tissues appear viable and the wound is clean (C). The goal is to minimize the bacterial load and optimize the biological environment before potentially introducing reamer debris. While immediate debridement is crucial, immediate reaming (B) without assessing tissue viability or if the wound is still grossly contaminated increases infection risk. Reaming is not always contraindicated (D) and wound size (A) is less important than viability. VAC (E) is an adjunct, not a prerequisite for reaming.

Question 9513

Topic: 2. Trauma

Which of the following principles is most important for achieving stable fixation with an intramedullary nail in a comminuted metaphyseal fracture extending into the diaphysis?

. A. Using a nail that completely fills the medullary canal for tight cortical contact.
. B. Achieving multiple points of stable locking (proximal and distal) to prevent shortening and rotation.
. C. Performing bone grafting at the fracture site to enhance healing.
. D. Ensuring the nail is at least 2 cm shorter than the bone length.
. E. Utilizing an unreamed nail to preserve endosteal blood supply.

Correct Answer & Explanation

. B. Achieving multiple points of stable locking (proximal and distal) to prevent shortening and rotation.


Explanation

For comminuted metaphyseal fractures extending into the diaphysis, the primary mechanical principle for stable fixation with an intramedullary nail is achieving multiple points of stable locking proximally and distally (B). This converts the nail into a load-bearing construct that can effectively control length, rotation, and angulation, especially when there is no direct cortical contact. While filling the canal (A) helps, locking is paramount for unstable fractures. Bone grafting (C) is a biological adjunct, not the primary mechanical principle. Nail length (D) should be appropriate, not necessarily shorter. Unreamed nails (E) prioritize biology but may offer less mechanical stability than reamed nails.

Question 9514

Topic: 2. Trauma
A 35-year-old male presents following a high-speed motor vehicle collision. He is hemodynamically stable. CT scan reveals a comminuted, unstable Tile C pelvic injury involving a sacral U-type fracture (Denis III) extending into the sacroiliac joint, and a contralateral pubic rami fracture. Neurological examination reveals a partial L5 nerve root palsy on the side of the sacral fracture. What is the most appropriate initial surgical management strategy for the posterior pelvic ring instability?
. Percutaneous iliosacral screw fixation of the sacral fracture and anterior external fixator.
. Open reduction and internal fixation of the sacral fracture via a posterior approach, combined with anterior plating of the pubic rami.
. Transiliac internal fixator (Ganz clamp) and anterior external fixator.
. Lumbopelvic fixation (spinopelvic instrumentation) extending from L4-S2 iliac combined with anterior external fixator.
. Open reduction and internal fixation of the sacral fracture via a posterior approach with sacroiliac joint fusion.

Correct Answer & Explanation

. Lumbopelvic fixation (spinopelvic instrumentation) extending from L4-S2 iliac combined with anterior external fixator.


Explanation

The patient has a comminuted, unstable sacral U-type fracture (Denis III) with an L5 nerve root palsy. U-type sacral fractures are highly unstable and often associated with neurological deficits. While percutaneous iliosacral screws can be used for some sacral fractures, they may not provide adequate stability for U-type fractures, especially with comminution and neurological involvement, which often indicates significant posterior column disruption. Open reduction via a posterior approach can be an option but might not provide sufficient stability for severe U-type fractures and has higher soft tissue morbidity. A transiliac internal fixator (Ganz clamp) is primarily for SI joint disruption or vertical shear injuries but less effective for comminuted sacral body fractures. Lumbopelvic fixation (spinopelvic instrumentation) is the most robust construct for highly unstable sacral fractures, particularly U-type or H-type fractures, especially when associated with neurological deficits, comminution, or when traditional iliosacral screws are deemed insufficient or contraindicated (e.g., due to fracture morphology, high sacral dysmorphism index, or need for reduction of severe displacement). It provides superior biomechanical stability compared to isolated iliosacral screws, allowing for precise reduction and decompression if needed. The anterior external fixator addresses the anterior pelvic ring instability. SI joint fusion is not the primary approach for acute unstable sacral fractures; it's more for chronic pain or degenerative conditions.

Question 9515

Topic: 2. Trauma

A 78-year-old female sustains a low-energy fall resulting in a Vancouver B2 periprosthetic femoral fracture around a well-fixed, extensively porous-coated uncemented total hip arthroplasty stem. The stem shows no signs of loosening on radiographs and appears stable. What is the most appropriate surgical management?

. Open reduction and internal fixation (ORIF) with plates and screws, retaining the existing stem.
. Revision to a long, extensively porous-coated femoral stem.
. Revision to a modular tapered fluted stem, bypassing the fracture site.
. Revision to a cemented stem with cerclage wires.
. Non-operative management with protected weight-bearing.

Correct Answer & Explanation

. Revision to a modular tapered fluted stem, bypassing the fracture site.


Explanation

A Vancouver B2 periprosthetic femoral fracture is defined as a fracture around aloosefemoral stem. Although the prompt mentions the stem 'shows no signs of loosening on radiographs and appears stable', the classification of B2 takes precedence, indicating the stem is compromised and requires revision. For a Vancouver B2 fracture, the existing loose stem must be revised, and the fracture needs stabilization. ORIF (A) retaining the existing stem is for Vancouver B1 fractures (well-fixed stem). Revision to a long, extensively porous-coated femoral stem (B) could be an option if distal fixation is assured, but may not adequately bypass the fracture. Revision to a cemented stem with cerclage wires (D) is less common as a primary revision strategy for B2 fractures with bone loss. Non-operative management (E) is not for unstable periprosthetic fractures. Therefore,revision to a modular tapered fluted stem, bypassing the fracture site (C)is generally the preferred choice for Vancouver B2 fractures. These stems achieve stable distal fixation in healthy bone beyond the fracture, and their modularity allows for appropriate restoration of limb length, offset, and version, providing a robust solution for a loose stem with associated fracture.

Question 9516

Topic: 2. Trauma

A 45-year-old male sustains a high-energy pilon fracture (distal tibia intra-articular fracture) with significant soft tissue swelling, blistering, and an open wound classified as Gustilo-Anderson Type I. Initial management includes meticulous wound debridement, provisional external fixation spanning the ankle, and intravenous antibiotics. On day 3, the soft tissue envelope appears less edematous, and the blisters are resolving, but the open wound requires further closure. What is the most appropriate next step in definitive management?

. Immediate open reduction and internal fixation (ORIF) of the articular surface and plating of the metaphysis.
. Delayed ORIF at 10-14 days after further soft tissue recovery.
. Medial malleolar osteotomy to improve articular visualization.
. Staged approach: limited internal fixation of the articular fragments, followed by definitive plating after several weeks.
. Below-knee amputation due to the severity of the injury.

Correct Answer & Explanation

. Staged approach: limited internal fixation of the articular fragments, followed by definitive plating after several weeks.


Explanation

This patient has a high-energy pilon fracture, compounded by significant soft tissue injury (blistering, Gustilo Type I open wound). The initial management (debridement, external fixation, antibiotics) is correct. The improving soft tissue conditions on day 3, with the open wound still requiring closure, indicates a need for careful timing. Immediate ORIF (A) is generally contraindicated in pilon fractures with severe soft tissue compromise due to high risks of wound breakdown and infection. Delayed ORIF at 10-14 days (B) is common for closed pilon fractures, but for an open fracture with significant articular comminution, a staged approach is safer. Medial malleolar osteotomy (C) is an adjunct, not the main strategy. Below-knee amputation (E) is a last resort. The most appropriate strategy is astaged approach (D). This typically involves an initial stage (already performed) of debridement and external fixation. The next step, often within 3-7 days when soft tissues improve, is a limited internal fixation of the articular fragments only (to restore the joint surface) followed by wound closure. Definitive plating of the metaphysis is then performed after 2-3 weeks, once the soft tissue envelope has fully recovered. This sequential approach minimizes soft tissue complications and optimizes the chances of a good outcome.

Question 9517

Topic: 2. Trauma

A 45-year-old male presents with severe pelvic pain and instability after a high-energy motor vehicle collision. Imaging reveals a bilateral sacroiliac joint disruption and a pubic symphysis diastasis of 4 cm. Neurological examination is intact. What is the most appropriate initial surgical management strategy?

. Anterior plating of the pubic symphysis alone.
. Percutaneous iliosacral screw fixation of one SI joint.
. External fixation of the pelvis.
. Combined anterior plating of the pubic symphysis and bilateral posterior sacral/iliac fixation.
. Posterior tension band wiring of the pubic symphysis and unilateral SI screw.

Correct Answer & Explanation

. Combined anterior plating of the pubic symphysis and bilateral posterior sacral/iliac fixation.


Explanation

This patient presents with a severe pelvic ring injury involving both anterior (pubic symphysis diastasis) and posterior (bilateral SI joint disruption) elements, indicating a vertically unstable pattern. Such injuries require robust stabilization of both the anterior and posterior pelvic rings. Anterior plating of the pubic symphysis addresses the anterior instability, while bilateral posterior sacral/iliac fixation (e.g., iliosacral screws or posterior plating) is crucial for stabilizing the posterior ring and preventing persistent vertical instability. Options A, B, C, and E represent incomplete or inadequate stabilization for this type of severe, unstable pelvic injury.

Question 9518

Topic: 2. Trauma
A 40-year-old male sustains a comminuted fracture of the coronoid process as part of a terrible triad injury of the elbow (radial head fracture, coronoid fracture, posterolateral dislocation). The coronoid fragment involves >50% of the coronoid height. What is the most appropriate management of the coronoid fracture in this setting?
. Excision of the coronoid fragment.
. Non-operative management with early mobilization.
. Fixation of the coronoid fragment.
. Radial head replacement alone.
. Hinge external fixator application without coronoid fixation.

Correct Answer & Explanation

. Fixation of the coronoid fragment.


Explanation

In a terrible triad injury, stability is key. Large coronoid fractures (>50% height or Regan and Morrey Type II/III) are critical for elbow stability, especially preventing recurrent posterior dislocation. Excision is contraindicated as it further destabilizes the elbow. Therefore, fixation of the coronoid fragment (e.g., suture lasso, screw fixation, or plate fixation depending on fragment size and configuration) is essential to restore anterior stability. Non-operative management or radial head replacement alone would not address the critical coronoid fracture. A hinge external fixator may be used as an adjunct but does not replace the need to fix the coronoid itself for primary stability.

Question 9519

Topic: 2. Trauma

A 30-year-old male presents with chronic exertional pain and tightness in his anterior compartment of the lower leg, which consistently develops after 15 minutes of running and resolves with rest. Physical examination is unremarkable at rest. What is the most accurate diagnostic test?

. MRI of the lower leg.
. Plain radiographs of the tibia.
. Intracompartmental pressure measurement during exercise.
. Nerve conduction studies.
. Arteriography of the lower leg.

Correct Answer & Explanation

. Intracompartmental pressure measurement during exercise.


Explanation

The clinical picture of exertional leg pain that consistently develops with activity and resolves with rest is classic for chronic exertional compartment syndrome (CECS). The most accurate and definitive diagnostic test for CECS is direct intracompartmental pressure measurement, performed before, immediately after, and at specified intervals (e.g., 1 and 5 minutes) after exercise. Elevated pressures confirm the diagnosis. MRI may show muscle edema but is not definitive. Plain radiographs are normal. Nerve conduction studies are for nerve entrapment, and arteriography for vascular insufficiency, which are differential diagnoses but not the primary cause of CECS.

Question 9520

Topic: 2. Trauma

A 45-year-old female sustains a pilon fracture (distal tibial plafond fracture) with severe comminution and significant soft tissue swelling after a fall from height. There is no open wound. Initial management includes external fixation for temporary stabilization. After 10 days, the soft tissue swelling has significantly decreased, and skin wrinkling is noted. What is the most appropriate next step in surgical management?

. Immediate definitive open reduction and internal fixation (ORIF).
. Continued external fixation for 6-8 weeks.
. Limited open reduction and internal fixation with a medial plate.
. Percutaneous screw fixation alone.
. External fixation removal and cast application.

Correct Answer & Explanation

. Immediate definitive open reduction and internal fixation (ORIF).


Explanation

Pilon fractures, especially high-energy comminuted ones, are associated with severe soft tissue injury. The 'staged approach' is critical for optimizing outcomes. Initial management involves temporary stabilization, often with spanning external fixation, to protect the soft tissues, allow swelling to subside, and minimize further damage. Once the soft tissues have 'declared themselves' (soft tissue envelope is ready, typically indicated by decreased swelling, skin wrinkling, and absence of blistering, usually 7-14 days post-injury), definitive ORIF is indicated. Delaying definitive fixation beyond this 'window of opportunity' or relying solely on external fixation for these complex fractures often leads to poorer outcomes (malunion, stiffness, nonunion). Therefore, immediate definitive ORIF (often using a combined anterior/posterior or medial/lateral approach depending on fracture pattern) is the next most appropriate step. Limited ORIF or percutaneous fixation might not be sufficient for severe comminution. Continued external fixation for 6-8 weeks would likely result in poor articular reduction and prolonged immobilization issues.
