Question 1061

Topic: Shoulder & Hip Sports

A 42-year-old manual laborer presents with anterior shoulder pain and mechanical catching. MRI reveals an isolated Type II SLAP tear. After 6 months of failed conservative management, he is scheduled for surgery. Based on current literature, what is the most appropriate surgical procedure for this patient?

. SLAP repair with superior suture anchors
. Biceps tenodesis
. Biceps tenotomy
. Debridement of the superior labrum without repair
. Open anterior capsulolabral reconstruction

Correct Answer & Explanation

. Biceps tenodesis


Explanation

In patients over the age of 35 to 40 with symptomatic Type II SLAP tears, primary biceps tenodesis yields superior clinical outcomes, lower reoperation rates, and higher return-to-work rates compared to SLAP repair, which has a higher risk of postoperative stiffness.

Question 1062

Topic: Shoulder & Hip Sports

A 65-year-old man presents with chronic right shoulder pain and an inability to actively elevate his arm above 60 degrees. Passive elevation is preserved. MRI shows a massive, retracted tear of the supraspinatus and infraspinatus with Goutallier stage 4 fatty infiltration. What is the most appropriate definitive surgical management?

. Arthroscopic rotator cuff repair
. Latissimus dorsi tendon transfer
. Superior capsular reconstruction
. Reverse total shoulder arthroplasty
. Hemiarthroplasty

Correct Answer & Explanation

. Reverse total shoulder arthroplasty


Explanation

Reverse total shoulder arthroplasty (RTSA) is the treatment of choice for older patients with pseudoparalysis and massive, irreparable rotator cuff tears with advanced fatty infiltration.

Question 1063

Topic: Shoulder & Hip Sports

A 45-year-old manual laborer presents with persistent anterior shoulder pain. MRI arthrogram reveals a Type II SLAP tear. Nonoperative management has failed. What is the most appropriate surgical intervention to minimize the risk of postoperative stiffness and maximize functional return?

. Arthroscopic SLAP repair using suture anchors
. Biceps tenotomy
. Coracoid transfer
. Biceps tenodesis
. Arthroscopic debridement of the labrum only

Correct Answer & Explanation

. Biceps tenodesis


Explanation

In patients over 40 years old, primary biceps tenodesis provides more reliable pain relief and functional return with less postoperative stiffness compared to primary SLAP repair.

Question 1064

Topic: Shoulder & Hip Sports

During diagnostic arthroscopy for chronic anterior shoulder instability, the surgeon identifies an impaction fracture of the anteroinferior glenoid rim with an associated disruption of the adjacent articular cartilage and labrum. What is the standard eponymous term for this lesion?

. Bankart lesion
. ALPSA lesion
. HAGL lesion
. GLAD lesion
. Perthes lesion

Correct Answer & Explanation

. GLAD lesion


Explanation

The Glenolabral Articular Disruption (GLAD) lesion is defined as a superficial anterior inferior labral tear associated with an articular cartilage injury of the glenoid.

Question 1065

Topic: Shoulder & Hip Sports

A 24-year-old overhead throwing athlete complains of deep shoulder pain during the late cocking phase of throwing. MRI arthrography reveals a Type II SLAP tear. Which of the following mechanisms is most responsible for this specific injury pattern in the overhead athlete?

. Direct traumatic impact to the glenohumeral joint
. Peel-back mechanism from torsional forces of the biceps anchor
. Eccentric overload of the supraspinatus tendon
. Subcoracoid impingement
. Internal impingement of the subscapularis

Correct Answer & Explanation

. Peel-back mechanism from torsional forces of the biceps anchor


Explanation

The peel-back mechanism occurs in the late cocking phase of throwing, where the biceps vector shifts posteriorly. This torsional force leads to the detachment of the superior labrum, resulting in a Type II SLAP tear.

Question 1066

Topic: Shoulder & Hip Sports

A 21-year-old collegiate linebacker presents with recurrent anterior shoulder instability. CT scan indicates 25% anterior glenoid bone loss. What is the most appropriate definitive management?

. Arthroscopic Bankart repair with suture anchors
. Arthroscopic capsular plication
. Latarjet procedure (coracoid transfer)
. Remplissage procedure alone
. Nonoperative management with bracing

Correct Answer & Explanation

. Latarjet procedure (coracoid transfer)


Explanation

Anterior glenoid bone loss exceeding 20-25% is a strict indication for a bony augmentation procedure like the Latarjet. Soft tissue repairs alone in this setting carry an unacceptably high recurrence rate.

Question 1067

Topic: Shoulder & Hip Sports

A 31-year-old volleyball player complains of isolated painless weakness in external rotation of his dominant shoulder. Examination reveals infraspinatus atrophy but normal supraspinatus strength. MRI is most likely to show a cyst in which location?

. Suprascapular notch
. Spinoglenoid notch
. Quadrilateral space
. Triangular interval
. Subcoracoid space

Correct Answer & Explanation

. Spinoglenoid notch


Explanation

The spinoglenoid notch transmits the suprascapular nerve to the infraspinatus only. A cyst here (often associated with posterior labral tears) causes isolated infraspinatus weakness without affecting the supraspinatus.

Question 1068

Topic: Shoulder & Hip Sports

A 45-year-old recreational tennis player has persistent anterior shoulder pain. MRI confirms a Type II SLAP (Superior Labrum Anterior to Posterior) tear. After failing 6 months of conservative management, surgical intervention is planned. Evidence suggests that which of the following produces the most reliable clinical outcomes and highest return to sport in this age group?

. SLAP repair using suture anchors
. Biceps tenodesis
. Arthroscopic debridement of the superior labrum
. Biceps tenotomy
. Coracoacromial ligament release

Correct Answer & Explanation

. Biceps tenodesis


Explanation

In patients over the age of 40 with a Type II SLAP tear, primary biceps tenodesis provides superior clinical outcomes, higher satisfaction, and more reliable return to sport compared to SLAP repair. SLAP repairs in older patients have higher rates of persistent pain and stiffness.

Question 1069

Topic: Shoulder & Hip Sports

A 21-year-old collegiate baseball pitcher presents with vague posterior shoulder pain. Physical exam reveals a Glenohumeral Internal Rotation Deficit (GIRD) of 25 degrees compared to the contralateral side, with a total arc of motion deficit of 15 degrees. What is the most appropriate initial treatment?

. Arthroscopic posterior capsular release
. Stretching of the posterior capsule utilizing sleeper stretches
. Superior labral repair
. Corticosteroid injection into the subacromial space
. Rotator interval closure

Correct Answer & Explanation

. Stretching of the posterior capsule utilizing sleeper stretches


Explanation

Pathologic GIRD is defined by a loss of internal rotation >20 degrees with a corresponding loss of total arc of motion >5 degrees. The first-line treatment is a dedicated physical therapy program emphasizing posterior capsular stretching (e.g., sleeper stretches, cross-body adduction).

Question 1070

Topic: Shoulder & Hip Sports

A 24-year-old competitive rugby player presents with recurrent anterior shoulder instability. CT scan shows a 25% anterior glenoid bone loss. Which of the following is the most appropriate surgical treatment?

. Arthroscopic Bankart repair
. Arthroscopic Remplissage
. Latarjet procedure
. Open inferior capsular shift
. Superior capsular reconstruction

Correct Answer & Explanation

. Latarjet procedure


Explanation

In contact athletes with critical anterior glenoid bone loss (>20-25%), an arthroscopic Bankart repair has an unacceptably high failure rate. The Latarjet procedure (coracoid transfer) is the gold standard for restoring stability in these patients.

Question 1071

Topic: Shoulder & Hip Sports

A 21-year-old collegiate baseball pitcher presents with vague posterior shoulder pain during the late cocking phase of throwing. Examination shows increased external rotation and a 25-degree loss of internal rotation compared to the contralateral side. What is the primary pathologic mechanism of this condition?

. Anterior capsular contracture
. Contracture of the posterior band of the inferior glenohumeral ligament
. Subscapularis tearing
. Acromioclavicular joint arthrosis
. Subacromial impingement

Correct Answer & Explanation

. Contracture of the posterior band of the inferior glenohumeral ligament


Explanation

Glenohumeral internal rotation deficit (GIRD) in throwers is primarily caused by contracture of the posterior capsule and posterior band of the inferior glenohumeral ligament (IGHL). This shifts the glenohumeral contact point posterosuperiorly, leading to internal impingement.

Question 1072

Topic: Shoulder & Hip Sports

A 45-year-old manual laborer has a massive, retracted, and irreparable posterosuperior rotator cuff tear. He has intact subscapularis function and severe external rotation weakness. Which of the following is the most appropriate surgical intervention to restore active external rotation?

. Pectoralis major transfer
. Latissimus dorsi transfer
. Lower trapezius transfer
. Superior capsular reconstruction
. Reverse total shoulder arthroplasty

Correct Answer & Explanation

. Latissimus dorsi transfer


Explanation

Latissimus dorsi transfer is indicated for younger, active patients with irreparable posterosuperior rotator cuff tears to restore active external rotation and forward elevation. An intact or reparable subscapularis is a prerequisite for success.

Question 1073

Topic: Shoulder & Hip Sports

A 45-year-old recreational tennis player has a symptomatic Type II SLAP tear that has failed conservative management. Current literature suggests that compared to primary SLAP repair, primary biceps tenodesis in this age group will likely result in:

. Higher rates of postoperative stiffness
. Lower return to sport rates
. Higher patient satisfaction and lower reoperation rates
. Increased risk of glenohumeral arthrosis
. Decreased elbow flexion strength

Correct Answer & Explanation

. Higher patient satisfaction and lower reoperation rates


Explanation

In patients older than 35-40 years with Type II SLAP tears, primary biceps tenodesis has been shown to yield higher patient satisfaction, lower rates of postoperative stiffness, and lower reoperation rates compared to SLAP repair.

Question 1074

Topic: Shoulder & Hip Sports

A 25-year-old male presents with recurrent anterior shoulder instability. Imaging and diagnostic arthroscopy reveal an anteroinferior glenoid bone loss of 28%. Which of the following procedures is most appropriate to restore stability and minimize recurrence in this patient?

. Arthroscopic Bankart repair with capsulorrhaphy
. Open Bankart repair
. Latarjet procedure (coracoid transfer)
. Remplissage procedure alone
. Subscapularis advancement

Correct Answer & Explanation

. Latarjet procedure (coracoid transfer)


Explanation

In the setting of critical glenoid bone loss (typically >20-25%), isolated soft tissue stabilization (Bankart repair) has an unacceptably high failure rate. A bone-block augmentation procedure, such as the Latarjet procedure, is indicated to restore the glenoid arc and provide a dynamic sling effect.

Question 1075

Topic: Shoulder & Hip Sports

A 14-year-old boy underwent in situ pinning for a stable SCFE 6 months ago. He now presents with worsening hip pain, a severe limp, and profound global restriction of hip motion. Radiographs show concentric narrowing of the joint space to less than 3 mm. What is the most likely diagnosis?

. Avascular necrosis (AVN)
. Chondrolysis
. Septic arthritis
. Implant failure
. Femoroacetabular impingement (FAI)

Correct Answer & Explanation

. Chondrolysis


Explanation

Chondrolysis is characterized by severe joint stiffness and diffuse joint space narrowing on radiographs. It is a known complication of SCFE, highly associated with unrecognized pin penetration into the joint space.

Question 1076

Topic: Shoulder & Hip Sports

A 25-year-old male presents with groin pain exacerbated by hip flexion and internal rotation. He has a history of mild SCFE treated with in situ pinning at age 13. Radiographs show a prominent alpha angle and a "pistol grip" deformity. What type of femoroacetabular impingement (FAI) is most likely occurring?

. Pincer impingement
. Cam impingement
. Ischiofemoral impingement
. Subspine impingement
. Psoas impingement

Correct Answer & Explanation

. Cam impingement


Explanation

SCFE commonly alters the proximal femoral anatomy, leaving a prominent metaphysis at the anterolateral head-neck junction. This leads to classic symptomatic Cam-type femoroacetabular impingement.

Question 1077

Topic: Shoulder & Hip Sports

A 13-year-old girl underwent an uncomplicated in situ pinning for a stable SCFE 6 months ago. She now returns with a stiff, painful hip and severe limitation in all planes of motion. Radiographs demonstrate profound global joint space narrowing (less than 3 mm). What is the most likely etiology of her current condition?

. Avascular necrosis (AVN) of the femoral head
. Chondrolysis of the hip joint
. Late-onset septic arthritis
. Cam-type femoroacetabular impingement (FAI)
. Hardware failure and backing out of the screw

Correct Answer & Explanation

. Chondrolysis of the hip joint


Explanation

Chondrolysis is characterized by an acute loss of articular cartilage, presenting with severe multidirectional stiffness and concentric joint space narrowing (<3mm). It is strongly associated with unrecognized intra-articular hardware penetration during SCFE pinning.

Question 1078

Topic: Shoulder & Hip Sports

A 65-year-old woman sustains a first-time traumatic anterior shoulder dislocation. After successful closed reduction, she continues to have profound weakness in active shoulder abduction and external rotation. The most likely cause is:

. Axillary nerve neurapraxia
. Brachial plexus injury
. Rotator cuff tear
. Recurrent dislocation
. Deltoid muscle rupture

Correct Answer & Explanation

. Rotator cuff tear


Explanation

In patients older than 40 years, an anterior shoulder dislocation is highly associated with massive rotator cuff tears. Persistent weakness in abduction and external rotation post-reduction warrants an MRI to evaluate for a cuff tear.

Question 1079

Topic: Shoulder & Hip Sports

A 35-year-old man presents with a locked posterior shoulder dislocation following a seizure. CT scan reveals an anteromedial humeral head defect (reverse Hill-Sachs lesion) involving 35% of the articular surface. Which of the following is the most appropriate surgical management?

. Closed reduction and spica casting
. Open reduction and anterior Bankart repair
. Arthroscopic Latarjet procedure
. Transfer of the lesser tuberosity into the defect
. Total shoulder arthroplasty

Correct Answer & Explanation

. Transfer of the lesser tuberosity into the defect


Explanation

For locked posterior shoulder dislocations with an articular defect between 20% and 40%, a modified McLaughlin procedure (transferring the lesser tuberosity into the defect) is indicated. This restores rotational stability and prevents the defect from engaging the posterior glenoid rim.

Question 1080

Topic: Shoulder & Hip Sports

A 24-year-old sustains an anterior shoulder dislocation. Closed reduction in the emergency department is unsuccessful despite adequate procedural sedation and muscle relaxation. Which structure is most likely interposing and preventing closed reduction?

. Long head of the biceps tendon
. Glenoid labrum
. Infraspinatus tendon
. Middle glenohumeral ligament
. Coracohumeral ligament

Correct Answer & Explanation

. Long head of the biceps tendon


Explanation

Irreducible anterior shoulder dislocations are relatively rare and are most commonly caused by interposition of the long head of the biceps tendon, the subscapularis tendon, or fracture fragments. Open reduction is required to clear the interposed tissue.
