Question 1101

Topic: Shoulder & Hip Sports

During the physical examination of a patient with suspected rotator cuff pathology, which of the following tests is considered the most sensitive and specific for detecting an isolated tear of the upper border of the subscapularis tendon?

. Lift-off test
. Drop arm test
. Bear-hug test
. Neer impingement sign
. Jobe (empty can) test

Correct Answer & Explanation

. Bear-hug test


Explanation

The bear-hug test is highly sensitive for evaluating the upper portion of the subscapularis tendon. In contrast, the lift-off test primarily isolates the lower portion of the subscapularis muscle.

Question 1102

Topic: Shoulder & Hip Sports

A 30-year-old professional volleyball player presents with painless weakness in external rotation of the right shoulder. Physical examination reveals isolated atrophy in the infraspinatus fossa, while supraspinatus strength and bulk are perfectly normal. At which anatomic location is nerve compression most likely occurring?

. Suprascapular notch
. Spinoglenoid notch
. Quadrilateral space
. Triangular interval
. Spiral groove

Correct Answer & Explanation

. Spinoglenoid notch


Explanation

Compression of the suprascapular nerve at the spinoglenoid notch selectively denervates the infraspinatus muscle, causing isolated external rotation weakness. Compression more proximally at the suprascapular notch affects both the supraspinatus and infraspinatus.

Question 1103

Topic: Shoulder & Hip Sports

A 24-year-old man suffers an anterior shoulder dislocation. Prior to reduction, he has decreased sensation over the lateral aspect of his deltoid. Due to the involved nerve, which muscle's function must be most closely monitored for associated weakness?

. Teres major
. Teres minor
. Supraspinatus
. Infraspinatus
. Subscapularis

Correct Answer & Explanation

. Teres minor


Explanation

The axillary nerve provides sensation to the lateral shoulder via the superior lateral cutaneous nerve of the arm and motor innervation to the deltoid and teres minor. It is the most frequently injured nerve in anterior shoulder dislocations.

Question 1104

Topic: Shoulder & Hip Sports

A 22-year-old collision athlete presents with recurrent anterior shoulder instability. A 3D CT scan reveals 30% anterior glenoid bone loss. What is the most appropriate surgical intervention to minimize the risk of recurrent instability?

. Arthroscopic Bankart repair
. Arthroscopic Remplissage with Bankart repair
. Latarjet procedure
. Open inferior capsular shift
. Putti-Platt procedure

Correct Answer & Explanation

. Latarjet procedure


Explanation

Glenoid bone loss greater than 20-25% is considered a critical defect and a contraindication to isolated soft-tissue Bankart repair. A coracoid transfer (Latarjet procedure) is the standard of care to restore the osseous arc and provide a sling effect.

Question 1105

Topic: Shoulder & Hip Sports

A 70-year-old man presents with chronic, massive, irreparable rotator cuff tears of the supraspinatus and infraspinatus. Physical examination reveals pseudoparalysis of the shoulder with active forward elevation limited to 40 degrees. MRI demonstrates Goutallier stage 4 fatty infiltration of the torn tendons, but the teres minor and subscapularis remain intact. Which of the following is the most appropriate surgical management?

. Arthroscopic subacromial decompression and debridement
. Latissimus dorsi tendon transfer
. Arthroscopic superior capsular reconstruction
. Reverse total shoulder arthroplasty
. Pectoralis major tendon transfer

Correct Answer & Explanation

. Reverse total shoulder arthroplasty


Explanation

Reverse total shoulder arthroplasty is the treatment of choice for elderly patients with massive, irreparable rotator cuff tears and pseudoparalysis. It restores the mechanical advantage of the deltoid, reliably improving active forward elevation.

Question 1106

Topic: Shoulder & Hip Sports

A 24-year-old baseball pitcher complains of deep shoulder pain during the late cocking phase of throwing. MRI arthrogram reveals a Type II SLAP tear. Which of the following physical examination findings is most specific for identifying a SLAP lesion in this patient?

. Positive Neer impingement sign
. Positive Belly-press test
. Positive O'Brien (active compression) test
. Positive Hornblower's sign
. Positive Lift-off test

Correct Answer & Explanation

. Positive O'Brien (active compression) test


Explanation

The O'Brien (active compression) test is commonly used to evaluate for SLAP lesions. Pain elicited with the arm internally rotated (thumb down) that is relieved when the arm is externally rotated (thumb up) suggests superior labral pathology.

Question 1107

Topic: Shoulder & Hip Sports

A 36-year-old volleyball player complains of vague posterior shoulder pain and profound weakness in external rotation. MRI reveals a large paralabral cyst located in the spinoglenoid notch. Which of the following muscle denervation patterns is most likely present?

. Supraspinatus only
. Infraspinatus only
. Both Supraspinatus and Infraspinatus
. Teres minor only
. Subscapularis and Teres major

Correct Answer & Explanation

. Infraspinatus only


Explanation

The suprascapular nerve innervates the supraspinatus before passing through the spinoglenoid notch to innervate the infraspinatus. Therefore, compression at the spinoglenoid notch results in isolated infraspinatus weakness and atrophy.

Question 1108

Topic: Shoulder & Hip Sports

A 55-year-old manual laborer presents with persistent shoulder pain due to a symptomatic Type II SLAP tear that has failed conservative management. Given his age and occupation, which surgical procedure is associated with the most reliable clinical outcome and lowest rate of stiffness?

. Arthroscopic SLAP repair with anchors
. Open SLAP repair
. Biceps tenodesis
. Isolated biceps tenotomy
. Subacromial decompression alone

Correct Answer & Explanation

. Biceps tenodesis


Explanation

In patients older than 40-45 years, biceps tenodesis provides more reliable pain relief and functional outcomes for symptomatic SLAP tears compared to SLAP repair. SLAP repairs in older patients are associated with higher rates of postoperative stiffness and failure.

Question 1109

Topic: Shoulder & Hip Sports

A 19-year-old college football player sustains an acute anterior shoulder dislocation. MRI confirms an anterior labral tear (Bankart lesion). If he is treated nonoperatively with a sling, what is his approximate risk of recurrent instability?

. 10-20%
. 30-40%
. 50-60%
. 70-90%
. 100%

Correct Answer & Explanation

. 70-90%


Explanation

The risk of recurrent shoulder instability following an acute first-time anterior dislocation in a young athlete (under 20 years old) treated nonoperatively is extremely high, generally reported between 70% and 90%.

Question 1110

Topic: Shoulder & Hip Sports

A 35-year-old man presents to the ER after a grand mal seizure. His shoulder is locked in internal rotation. An AP radiograph shows a 'lightbulb sign.' What is the most common associated bony defect in this injury pattern?

. Hill-Sachs lesion
. Reverse Hill-Sachs lesion
. Bankart lesion
. Greater tuberosity fracture
. Coracoid process fracture

Correct Answer & Explanation

. Reverse Hill-Sachs lesion


Explanation

Posterior shoulder dislocations, classically presenting after seizures or electrical shock with a 'lightbulb' appearance on AP radiographs, are frequently associated with an impaction fracture of the anteromedial humeral head, known as a reverse Hill-Sachs lesion.

Question 1111

Topic: Shoulder & Hip Sports

A 22-year-old rugby player has recurrent anterior shoulder instability. CT scan demonstrates 25% glenoid bone loss and a large, engaging Hill-Sachs lesion. What is the most appropriate definitive management?

. Arthroscopic Bankart repair
. Arthroscopic Bankart repair with remplissage
. Latarjet procedure
. Open capsular shift
. Proximal humerus rotational osteotomy

Correct Answer & Explanation

. Latarjet procedure


Explanation

For recurrent anterior shoulder instability with critical glenoid bone loss (typically >20-25%), an arthroscopic soft tissue repair is insufficient. The Latarjet procedure (coracoid transfer) is indicated to restore the glenoid arc and provide a dynamic sling effect.

Question 1112

Topic: Shoulder & Hip Sports

A 45-year-old manual laborer presents with persistent shoulder pain. MRI confirms a Type II SLAP tear. After failing conservative management, surgical intervention is planned. To minimize the risk of post-operative stiffness and reoperation in this demographic, what is the preferred procedure?

. Arthroscopic SLAP repair
. Arthroscopic biceps tenodesis
. Biceps tenotomy without tenodesis
. Subacromial decompression alone
. Arthroscopic posterior capsular release

Correct Answer & Explanation

. Arthroscopic biceps tenodesis


Explanation

In patients older than 40, primary biceps tenodesis yields better clinical outcomes, higher satisfaction, and lower reoperation rates compared to arthroscopic SLAP repair for Type II lesions.

Question 1113

Topic: Shoulder & Hip Sports

A 22-year-old competitive rugby player presents with recurrent anterior shoulder instability. A 3D CT scan reveals 28% bone loss of the anterior/inferior glenoid. Which surgical procedure is most appropriate?

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

Correct Answer & Explanation

. Coracoid transfer (Latarjet procedure)


Explanation

Anterior glenoid bone loss greater than 20-25% (critical bone loss) is an indication for a bony augmentation procedure, such as the Latarjet procedure. Soft tissue repairs alone have an unacceptably high failure rate in this setting.

Question 1114

Topic: Shoulder & Hip Sports

A 45-year-old manual laborer presents with a massive, irreparable posterosuperior rotator cuff tear. Examination reveals an intact subscapularis and deltoid, but he has significant weakness in active external rotation and forward elevation. Which of the following tendon transfers is the most appropriate surgical treatment to restore function?

. Pectoralis major transfer
. Latissimus dorsi transfer
. Serratus anterior transfer
. Rhomboid major transfer
. Levator scapulae transfer

Correct Answer & Explanation

. Latissimus dorsi transfer


Explanation

Latissimus dorsi transfer is indicated for young, active patients with massive, irreparable posterosuperior cuff tears (supraspinatus and infraspinatus) who have an intact subscapularis and deltoid. It helps restore active external rotation and forward elevation.

Question 1115

Topic: Shoulder & Hip Sports

A 22-year-old competitive rugby player with a history of recurrent anterior shoulder dislocations undergoes advanced imaging. A 3D CT scan reveals a 28% anterior glenoid bone defect. What is the most appropriate definitive surgical intervention?

. Arthroscopic Bankart repair with Remplissage
. Open Bankart repair
. Coracoid transfer (Latarjet procedure)
. Arthroscopic capsular shift
. Putti-Platt procedure

Correct Answer & Explanation

. Coracoid transfer (Latarjet procedure)


Explanation

In collision athletes with critical glenoid bone loss (typically > 20-25%), isolated soft-tissue stabilization (Bankart repair) has unacceptably high failure rates. A bone-block procedure, such as the Latarjet (coracoid transfer), is the standard of care.

Question 1116

Topic: Shoulder & Hip Sports

A 21-year-old collegiate wrestler has experienced multiple anterior shoulder dislocations. A recent CT scan indicates 30% anterior glenoid bone loss. What is the most appropriate surgical intervention to prevent recurrent instability?

. Arthroscopic Bankart repair with suture anchors
. Open Bankart repair and capsular shift
. Coracoid transfer to the anterior glenoid (Latarjet procedure)
. Remplissage procedure alone
. Subscapularis tendon transfer

Correct Answer & Explanation

. Coracoid transfer to the anterior glenoid (Latarjet procedure)


Explanation

Anterior glenoid bone loss exceeding 20-25% is a strict contraindication for isolated soft-tissue procedures like a Bankart repair. A bony augmentation procedure, such as the Latarjet (coracoid transfer), is required to restore the glenoid articular arc.

Question 1117

Topic: Shoulder & Hip Sports

A 21-year-old collegiate rugby player with a history of multiple recurrent anterior shoulder dislocations undergoes evaluation. A CT scan with 3D reconstruction reveals a 28% anterior glenoid bone loss. What is the most appropriate surgical intervention?

. Arthroscopic Bankart repair
. Open capsular shift
. Latarjet procedure
. Arthroscopic remplissage procedure
. Putti-Platt procedure

Correct Answer & Explanation

. Latarjet procedure


Explanation

Critical glenoid bone loss (typically > 20-25%) is a direct contraindication to an isolated soft-tissue Bankart repair due to unacceptably high recurrence rates. The Latarjet procedure (coracoid transfer) is the gold standard, effectively restoring the bony arc and providing a dynamic soft-tissue sling.

Question 1118

Topic: Shoulder & Hip Sports

A 22-year-old collegiate rugby player presents with recurrent anterior shoulder instability. A 3D CT scan demonstrates 25% anterior glenoid bone loss.

Which of the following is the most appropriate definitive management?

. Arthroscopic Bankart repair with suture anchors
. Open Bankart repair and inferior capsular shift
. Coracoid transfer to the anterior glenoid (Latarjet procedure)
. Arthroscopic Remplissage procedure
. Humeral head osteochondral allograft

Correct Answer & Explanation

. Coracoid transfer to the anterior glenoid (Latarjet procedure)


Explanation

Critical glenoid bone loss (typically >20-25%) in a contact athlete is a primary indication for a bony augmentation procedure like the Latarjet. Arthroscopic soft-tissue repairs alone in this setting have an unacceptably high failure rate.

Question 1119

Topic: Shoulder & Hip Sports

A 22-year-old collegiate football player presents with his third anterior shoulder dislocation. Imaging reveals an engaged Hill-Sachs lesion and 25% anterior glenoid bone loss. What is the most appropriate surgical management?

. Arthroscopic Bankart repair
. Open Bankart repair with inferior capsular shift
. Latarjet procedure
. Arthroscopic remplissage alone
. Total shoulder arthroplasty

Correct Answer & Explanation

. Latarjet procedure


Explanation

In the setting of recurrent anterior instability with critical glenoid bone loss (greater than 20-25%), a soft tissue repair alone has an unacceptably high failure rate. The Latarjet procedure (coracoid transfer) addresses the bony defect and provides a sling effect via the conjoint tendon.

Question 1120

Topic: Shoulder & Hip Sports

A 45-year-old laborer with chronic shoulder pain has failed 6 months of physical therapy. MRI demonstrates a Type II SLAP tear without rotator cuff pathology. Based on recent literature, which surgical intervention provides the most reliable functional outcome in this demographic?

. Arthroscopic SLAP repair
. Subpectoral biceps tenodesis
. Distal clavicle excision
. Coracoacromial ligament release
. Thermal capsulorrhaphy

Correct Answer & Explanation

. Subpectoral biceps tenodesis


Explanation

In patients older than 40 years with symptomatic Type II SLAP tears, biceps tenodesis provides superior clinical outcomes and a lower revision rate compared to arthroscopic SLAP repair. SLAP repairs in older patients often result in postoperative stiffness and persistent pain.
