Question 1041

Topic: Shoulder & Hip Sports

The arthroscopic Remplissage procedure is utilized as an adjunct to a Bankart repair in cases of significant, engaging Hill-Sachs lesions without critical glenoid bone loss. Which anatomical structure is tenodesed into the humeral defect during this procedure?

. Supraspinatus tendon
. Subscapularis tendon
. Infraspinatus tendon
. Teres minor tendon
. Long head of the biceps tendon

Correct Answer & Explanation

. Infraspinatus tendon


Explanation

The Remplissage procedure involves capsulotenodesis of the infraspinatus tendon and posterior capsule into a large Hill-Sachs defect. This essentially makes the defect extra-articular and prevents it from engaging on the anterior glenoid rim during abduction and external rotation.

Question 1042

Topic: Shoulder & Hip Sports

A 35-year-old man presents to the emergency department after a first-time seizure. His arm is locked in internal rotation and adduction. Radiographs reveal a posterior shoulder dislocation. A subsequent CT scan shows an anteromedial humeral head defect involving 30% of the articular surface. Following closed reduction, the shoulder remains unstable in internal rotation. What is the most appropriate surgical management?

. Arthroscopic posterior Bankart repair
. Coracoid transfer to the posterior glenoid
. Transfer of the lesser tuberosity into the defect
. Open reduction and internal fixation of the greater tuberosity
. Arthroscopic remplissage

Correct Answer & Explanation

. Transfer of the lesser tuberosity into the defect


Explanation

For a reverse Hill-Sachs defect involving 20% to 40% of the articular surface, transferring the lesser tuberosity with the attached subscapularis into the defect (modified McLaughlin procedure) prevents the defect from engaging the posterior glenoid rim.

Question 1043

Topic: Shoulder & Hip Sports

A 20-year-old rugby player evaluates for recurrent anterior shoulder instability. A 3D CT scan reveals 25% anterior glenoid bone loss. MRI shows an engaging Hill-Sachs lesion. Based on the glenoid track concept, which of the following procedures is most appropriate to minimize the risk of recurrent instability?

. Arthroscopic Bankart repair alone
. Arthroscopic Bankart repair with Remplissage
. Coracoid transfer (Latarjet procedure)
. Anterior opening wedge glenoid osteotomy
. Superior capsular reconstruction

Correct Answer & Explanation

. Coracoid transfer (Latarjet procedure)


Explanation

Critical glenoid bone loss (>20%) requires bony augmentation, such as the Latarjet procedure, to restore the glenoid arc and stability. Arthroscopic Bankart with Remplissage is reserved for subcritical bone loss with an off-track Hill-Sachs lesion.

Question 1044

Topic: Shoulder & Hip Sports

A 23-year-old professional baseball pitcher complains of vague posterior shoulder pain during the late cocking phase of throwing. Physical examination reveals a 25-degree glenohumeral internal rotation deficit (GIRD) compared to the contralateral side, and a positive peel-back sign on arthroscopic simulation. What is the recommended initial management?

. Arthroscopic Type II SLAP repair
. Arthroscopic posterior capsule release
. Anterior capsulolabral plication
. Sleeper stretches and posterior cuff strengthening
. Subpectoral biceps tenodesis

Correct Answer & Explanation

. Sleeper stretches and posterior cuff strengthening


Explanation

Symptomatic GIRD with internal impingement and posterior labral peel-back in throwing athletes initially responds well to a stretching program targeting the posterior capsule (sleeper stretches). Operative intervention is reserved only for refractory cases after a prolonged course of therapy.

Question 1045

Topic: Shoulder & Hip Sports

A 20-year-old collegiate rugby player presents with recurrent anterior shoulder instability. A 3D CT scan reveals 25% anterior glenoid bone loss. What is the most appropriate surgical management?

. Arthroscopic Bankart repair
. Open Bankart repair
. Arthroscopic Remplissage
. Latarjet procedure
. Capsular shift

Correct Answer & Explanation

. Latarjet procedure


Explanation

The Latarjet procedure (coracoid transfer) is indicated for recurrent anterior shoulder instability in the presence of critical glenoid bone loss (>20-25%). Soft tissue stabilization alone in this setting has an unacceptably high failure rate.

Question 1046

Topic: Shoulder & Hip Sports

A 32-year-old recreational volleyball player is diagnosed with a Type II SLAP tear. What differentiates a Type II from a Type I SLAP tear?

. Fraying of the superior labrum with an intact biceps anchor
. Detachment of the superior labrum and biceps anchor from the glenoid
. Bucket-handle tear of the superior labrum with an intact biceps anchor
. Bucket-handle tear of the superior labrum with detachment of the biceps anchor
. Involvement of the middle glenohumeral ligament

Correct Answer & Explanation

. Detachment of the superior labrum and biceps anchor from the glenoid


Explanation

A Type II SLAP tear involves detachment of the superior labrum and the long head of the biceps anchor from the superior glenoid. Type I is merely degenerative fraying with an intact anchor.

Question 1047

Topic: Shoulder & Hip Sports

A 28-year-old male volleyball player presents with painless weakness in external rotation of his right shoulder. MRI reveals a paralabral cyst in the spinoglenoid notch. Which muscle is predominantly affected?

. Supraspinatus
. Infraspinatus
. Teres minor
. Subscapularis
. Deltoid

Correct Answer & Explanation

. Infraspinatus


Explanation

A cyst in the spinoglenoid notch typically compresses the suprascapular nerve after it has already innervated the supraspinatus. This leads to isolated atrophy and weakness of the infraspinatus muscle.

Question 1048

Topic: Shoulder & Hip Sports

During a routine arthroscopic rotator cuff repair, a patient is noted to have an isolated, complete rupture of the subscapularis tendon. Which physical examination test would have been most definitively positive preoperatively?

. Jobe's (empty can) test
. Hornblower's sign
. Bear hug test
. O'Brien's active compression test
. Speed's test

Correct Answer & Explanation

. Bear hug test


Explanation

The Bear hug test, lift-off test, and belly-press test are specific for subscapularis pathology. Hornblower's assesses the teres minor, while Jobe's is specific for the supraspinatus.

Question 1049

Topic: Shoulder & Hip Sports

A 22-year-old collegiate baseball pitcher reports deep shoulder pain during the late-cocking phase of throwing. He demonstrates a positive O'Brien test and a positive pronated load test. What is the most likely pathophysiologic mechanism of this injury?

. Tension overload of the anterior band of the inferior glenohumeral ligament
. Peel-back of the superior labrum from torsional forces of the biceps anchor
. Internal impingement of the supraspinatus tendon against the posterosuperior glenoid
. Eccentric overload of the posterior rotator cuff during deceleration
. Traction injury to the suprascapular nerve at the suprascapular notch

Correct Answer & Explanation

. Peel-back of the superior labrum from torsional forces of the biceps anchor


Explanation

The peel-back mechanism occurs during the late cocking phase of throwing (abduction and maximal external rotation), causing a torsional force at the biceps anchor that peels the superior labrum off the glenoid rim. This leads to a type II SLAP tear.

Question 1050

Topic: Shoulder & Hip Sports

A 28-year-old professional tennis player presents with right shoulder pain. Physical examination reveals a glenohumeral internal rotation deficit (GIRD) of 25 degrees compared to the contralateral side, alongside normal overall arc of motion. What is the most appropriate initial treatment?

. Anterior capsular release
. Arthroscopic superior labral repair
. Sleeper stretch exercises focusing on the posterior capsule
. Posterior capsular plication
. Subacromial corticosteroid injection

Correct Answer & Explanation

. Sleeper stretch exercises focusing on the posterior capsule


Explanation

GIRD is caused by contracture of the posterior-inferior capsule resulting from repetitive overhead activities. The initial treatment of choice is physical therapy focusing on sleeper stretches to selectively stretch the posterior capsule.

Question 1051

Topic: Shoulder & Hip Sports

A 21-year-old collegiate volleyball player complains of vague, deep posterior shoulder pain.

She has normal strength with shoulder abduction, but notable weakness with external rotation when the arm is positioned at the side. At which anatomic site is the affected nerve most likely compressed?

. Quadrilateral space
. Spinoglenoid notch
. Suprascapular notch
. Spiral groove
. Thoracic outlet

Correct Answer & Explanation

. Spinoglenoid notch


Explanation

Isolated weakness of the infraspinatus (external rotation) with normal supraspinatus function (abduction) points to suprascapular nerve entrapment at the spinoglenoid notch. This is classic in volleyball players due to repetitive overhead serving or associated paralabral cysts.

Question 1052

Topic: Shoulder & Hip Sports

A 20-year-old rugby player presents with recurrent anterior shoulder instability. A 3D CT scan demonstrates 25% glenoid bone loss. Which surgical procedure is most indicated?

. Arthroscopic Bankart repair
. Open Bankart repair with inferior capsular shift
. Latarjet procedure
. Arthroscopic remplissage alone
. Subscapularis advancement

Correct Answer & Explanation

. Latarjet procedure


Explanation

Critical glenoid bone loss is generally defined as >20-25% of the anterior glenoid. In these cases, soft tissue stabilization (Bankart repair) has unacceptably high failure rates, and a bone block augmentation such as the Latarjet procedure is indicated.

Question 1053

Topic: Shoulder & Hip Sports

A 24-year-old elite baseball pitcher presents with vague, deep shoulder pain during the late cocking phase of throwing. MRI confirms an isolated Type II SLAP tear. After confirming a glenohumeral internal rotation deficit (GIRD), what is the most appropriate initial management?

. Arthroscopic SLAP repair
. Biceps tenodesis
. Biceps tenotomy
. Physical therapy focusing on posterior capsular stretching
. Open anterior capsulolabral reconstruction

Correct Answer & Explanation

. Physical therapy focusing on posterior capsular stretching


Explanation

Overhead athletes with Type II SLAP tears and GIRD should undergo a trial of physical therapy focusing on stretching the contracted posterior capsule (sleeper stretches). Surgical repair is reserved for those who fail prolonged conservative management.

Question 1054

Topic: Shoulder & Hip Sports

An elite overhead throwing athlete presents with posterior shoulder pain during the late cocking phase. Which combination of intra-articular pathology is most characteristic of internal impingement?

. Anterior-inferior labral tear and subscapularis tear
. Posterosuperior labral fraying and undersurface tearing of the posterior supraspinatus/anterior infraspinatus
. SLAP tear and biceps subluxation
. Subacromial bursitis and bursal-sided rotator cuff tears
. Adhesive capsulitis and glenohumeral arthritis

Correct Answer & Explanation

. Posterosuperior labral fraying and undersurface tearing of the posterior supraspinatus/anterior infraspinatus


Explanation

Internal impingement occurs in maximum abduction and external rotation, causing the undersurface of the posterior supraspinatus and anterior infraspinatus to impinge against the posterosuperior glenoid labrum, leading to fraying and partial tearing of both structures.

Question 1055

Topic: Shoulder & Hip Sports

A 26-year-old professional volleyball player complains of vague posterior shoulder pain and profound weakness in external rotation.

MRI reveals a paralabral cyst in the spinoglenoid notch. Which muscle would exhibit isolated weakness on clinical exam?

. Supraspinatus
. Infraspinatus
. Teres minor
. Subscapularis
. Deltoid

Correct Answer & Explanation

. Infraspinatus


Explanation

The suprascapular nerve innervates the supraspinatus before passing through the spinoglenoid notch to innervate the infraspinatus. A cyst at the spinoglenoid notch compresses the distal nerve, causing isolated infraspinatus atrophy and external rotation weakness.

Question 1056

Topic: Shoulder & Hip Sports

A 22-year-old competitive rugby player presents with recurrent anterior shoulder instability. Radiographs and a 3D CT scan demonstrate 25% anterior glenoid bone loss and an engaging Hill-Sachs lesion. What is the most appropriate definitive surgical management?

. Arthroscopic Bankart repair
. Arthroscopic Bankart repair with Remplissage
. Open Bankart repair
. Coracoid transfer (Latarjet procedure)
. Arthroscopic superior capsular reconstruction

Correct Answer & Explanation

. Coracoid transfer (Latarjet procedure)


Explanation

In high-demand collision athletes with critical anterior glenoid bone loss (typically >20-25%), a bone-block augmentation such as the Latarjet procedure is indicated to restore stability. Arthroscopic soft tissue repairs in the setting of critical bone loss have an unacceptably high failure rate.

Question 1057

Topic: Shoulder & Hip Sports

A 45-year-old recreational tennis player presents with persistent deep shoulder pain and mechanical catching. An MRI arthrogram reveals an isolated Type II SLAP tear. After failing 6 months of physical therapy, operative intervention is selected. Which of the following procedures is most likely to yield the highest patient satisfaction and lowest reoperation rate?

. Arthroscopic SLAP repair with suture anchors
. Arthroscopic debridement of the labrum only
. Open anterior capsulolabral repair
. Arthroscopic biceps tenodesis
. Arthroscopic superior capsular reconstruction

Correct Answer & Explanation

. Arthroscopic biceps tenodesis


Explanation

In patients older than 40 years, primary biceps tenodesis for symptomatic Type II SLAP tears provides superior clinical outcomes and lower reoperation rates compared to SLAP repair. SLAP repair in this age group is frequently associated with increased postoperative stiffness, continued pain, and higher revision rates.

Question 1058

Topic: Shoulder & Hip Sports

A 20-year-old collegiate baseball pitcher complains of posterior shoulder pain during the late cocking phase of throwing. Examination demonstrates a 25-degree glenohumeral internal rotation deficit (GIRD) compared to the contralateral shoulder. The pathophysiology of internal impingement in this athlete most likely involves abnormal contact between the posterosuperior labrum and the:

. Undersurface of the subscapularis tendon
. Undersurface of the infraspinatus and supraspinatus tendons
. Biceps anchor and superior glenohumeral ligament
. Anterosuperior labrum
. Coracoacromial ligament

Correct Answer & Explanation

. Undersurface of the infraspinatus and supraspinatus tendons


Explanation

Internal impingement occurs during maximum abduction and external rotation (late cocking phase), causing the articular surface of the posterior supraspinatus and anterior infraspinatus to impinge against the posterosuperior glenoid labrum. This pathologic contact is frequently exacerbated by GIRD and posterior capsular contracture.

Question 1059

Topic: Shoulder & Hip Sports

A 24-year-old professional baseball pitcher complains of posterior shoulder pain during the late cocking phase of throwing. MRI arthrography reveals a partial-thickness articular-sided tear of the supraspinatus and posterosuperior labral fraying. What is the most likely pathomechanical cause of this condition?

. Subcoracoid impingement
. Glenohumeral internal rotation deficit (GIRD) and posterior capsular contracture
. Primary anterior capsular laxity
. Congenital glenoid retroversion
. Scapular winging secondary to long thoracic nerve palsy

Correct Answer & Explanation

. Glenohumeral internal rotation deficit (GIRD) and posterior capsular contracture


Explanation

Internal impingement occurs when the greater tuberosity abuts the posterosuperior glenoid during maximum external rotation and abduction. This is strongly associated with GIRD and a contracted posterior capsule, which shifts the humeral head posterosuperiorly during the throwing motion.

Question 1060

Topic: Shoulder & Hip Sports

A 19-year-old competitive rugby player presents with recurrent anterior shoulder instability. A 3D CT scan demonstrates 22% anterior glenoid bone loss and a non-engaging Hill-Sachs lesion. Which of the following is the most appropriate surgical intervention?

. Arthroscopic Bankart repair with suture anchors
. Arthroscopic Remplissage and Bankart repair
. Open Latarjet procedure
. Open inferior capsular shift
. Arthroscopic superior capsular reconstruction

Correct Answer & Explanation

. Open Latarjet procedure


Explanation

Anterior glenoid bone loss greater than 20% (or 13.5-15% in high-risk collision athletes) is a well-established indication for a bone block procedure like the Latarjet. Arthroscopic soft-tissue repair in the setting of critical bone loss carries an unacceptably high failure rate.
