Question 5221

Topic: Shoulder & Hip Sports

A 55-year-old laborer has an irreparable, massive posterosuperior rotator cuff tear with an intact subscapularis. He lacks active external rotation. Which tendon transfer is most appropriate?

. Pectoralis major
. Pectoralis minor
. Lower trapezius
. Levator scapulae
. Biceps brachii

Correct Answer & Explanation

. Lower trapezius


Explanation

Lower trapezius transfer (often with an interposition graft) is used to restore active external rotation in patients with an irreparable posterosuperior rotator cuff tear. Pectoralis major transfers are typically utilized for irreparable subscapularis tears.

Question 5222

Topic: Shoulder & Hip Sports

Which physical examination test provides the highest sensitivity and specificity for diagnosing an upper border subscapularis tear?

. Lift-off test
. Belly-press test
. Bear-hug test
. Hornblower's sign
. Neer impingement sign

Correct Answer & Explanation

. Bear-hug test


Explanation

The bear-hug test has been shown to be highly sensitive and specific for upper subscapularis tendon tears. The lift-off test predominantly isolates the lower fibers of the subscapularis.

Question 5223

Topic: Shoulder & Hip Sports

A 22-year-old collegiate baseball pitcher complains of posterior shoulder pain during the late cocking phase of throwing. He has a positive apprehension test, but pain is relieved with a relocation maneuver. What is the primary pathomechanics of this condition?

. Primary subacromial impingement
. Acromioclavicular joint osteoarthritis
. Anterosuperior labral tearing
. Contact between the articular surface of the rotator cuff and the posterosuperior glenoid
. Subcoracoid impingement

Correct Answer & Explanation

. Contact between the articular surface of the rotator cuff and the posterosuperior glenoid


Explanation

Internal impingement in overhead throwing athletes occurs due to contact between the articular side of the posterosuperior rotator cuff and the posterosuperior labrum/glenoid during extreme abduction and external rotation.

Question 5224

Topic: Shoulder & Hip Sports

A 30-year-old professional volleyball player presents with isolated atrophy and weakness of the infraspinatus muscle. MRI reveals a paralabral cyst. At which of the following locations is the cyst most likely compressing the nerve?

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

Correct Answer & Explanation

. Spinoglenoid notch


Explanation

Compression of the suprascapular nerve at the spinoglenoid notch causes isolated infraspinatus weakness. Compression at the suprascapular notch generally affects both the supraspinatus and infraspinatus.

Question 5225

Topic: Shoulder & Hip Sports

During a Latarjet procedure, the coracoid is transferred through the subscapularis split. Which nerve is most at risk of injury when dissecting medial to the conjoint tendon?

. Axillary nerve
. Musculocutaneous nerve
. Radial nerve
. Ulnar nerve
. Median nerve

Correct Answer & Explanation

. Musculocutaneous nerve


Explanation

The musculocutaneous nerve penetrates the coracobrachialis approximately 3-5 cm distal to the coracoid process. It is the structure most at risk when dissecting medial to the conjoint tendon during a Latarjet procedure.

Question 5226

Topic: Shoulder & Hip Sports

A 22-year-old collegiate rugby player presents with his fourth anterior shoulder dislocation this season. A 3D CT scan demonstrates a 25% anterior glenoid bone loss. He wishes to return to contact sports. What is the most appropriate definitive surgical management?

. Arthroscopic Bankart repair
. Open Latarjet procedure
. Arthroscopic remplissage
. Reverse total shoulder arthroplasty
. Open inferior capsular shift

Correct Answer & Explanation

. Open Latarjet procedure


Explanation

A glenoid bone loss of greater than 20-25% is a critical defect associated with high failure rates following soft-tissue (Bankart) repair alone. The Latarjet procedure transfers the coracoid process to the anterior glenoid, restoring the bony arc and providing a dynamic sling effect via the conjoined tendon.

Question 5227

Topic: Shoulder & Hip Sports

A 31-year-old professional volleyball player presents with painless weakness in shoulder external rotation. Abduction strength is normal. MRI demonstrates a paralabral cyst causing nerve compression. Where is the cyst most likely located?

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

Correct Answer & Explanation

. Spinoglenoid notch


Explanation

Isolated weakness of the infraspinatus (external rotation) with normal supraspinatus function (abduction) indicates suprascapular nerve entrapment at the spinoglenoid notch. Compression at the suprascapular notch would affect both the supraspinatus and infraspinatus.

Question 5228

Topic: Shoulder & Hip Sports

A 22-year-old contact athlete experiences recurrent anterior shoulder dislocations. CT imaging demonstrates a 25% anteroinferior glenoid bone loss. Which of the following is the most appropriate definitive surgical management?

. Arthroscopic Bankart repair
. Arthroscopic Remplissage
. Latarjet procedure
. Open Bankart repair
. Putti-Platt procedure

Correct Answer & Explanation

. Latarjet procedure


Explanation

The Latarjet procedure (coracoid transfer) is indicated for anterior shoulder instability in patients with greater than 20-25% glenoid bone loss. Soft tissue repairs alone have an unacceptably high failure rate in young contact athletes with significant bone loss.

Question 5229

Topic: Shoulder & Hip Sports

A 45-year-old male presents with shoulder pain and weakness following a fall. Physical examination reveals a positive bear hug test and a positive belly press test. Which of the following rotator cuff tendons is most likely injured?

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

Correct Answer & Explanation

. Subscapularis


Explanation

The bear hug and belly press tests are highly sensitive and specific for evaluating subscapularis integrity. These tests isolate the subscapularis function from the other internal rotators like the pectoralis major.

Question 5230

Topic: Shoulder & Hip Sports

A 28-year-old elite volleyball player complains of vague posterior shoulder pain and weakness. Examination shows isolated atrophy of the infraspinatus. An MRI confirms a paralabral cyst causing nerve compression. Where is the most likely location of this cyst?

. Suprascapular notch
. Spinoglenoid notch
. Quadrilateral space
. Triangular interval
. Supraclavicular fossa

Correct Answer & Explanation

. Spinoglenoid notch


Explanation

Entrapment of the suprascapular nerve at the spinoglenoid notch results in isolated infraspinatus weakness and atrophy. Entrapment at the suprascapular notch would affect both the supraspinatus and the infraspinatus.

Question 5231

Topic: Shoulder & Hip Sports

A 35-year-old male presents with two weeks of sudden, severe, unrelenting right shoulder pain. As the pain subsides, he develops profound weakness in shoulder abduction and external rotation. EMG shows denervation of the deltoid and supraspinatus. What is the most likely diagnosis?

. Cervical spondylotic myelopathy
. Massive rotator cuff tear
. Parsonage-Turner syndrome (Neuralgic amyotrophy)
. Pancoast tumor
. Adhesive capsulitis

Correct Answer & Explanation

. Parsonage-Turner syndrome (Neuralgic amyotrophy)


Explanation

Parsonage-Turner syndrome presents with an acute onset of severe, unrelenting shoulder pain followed by patchy muscle weakness and atrophy as the pain subsides. It is an idiopathic brachial neuritis typically treated supportively.

Question 5232

Topic: Shoulder & Hip Sports

A 45-year-old recreational tennis player has persistent shoulder pain despite 6 months of nonoperative management. An MRI arthrogram shows an isolated Type II SLAP tear. What is the most predictable surgical treatment to relieve his pain and restore function?

. Arthroscopic SLAP repair with suture anchors
. Biceps tenodesis
. Biceps tenotomy
. Arthroscopic extensive labral debridement
. Open anterior Bankart repair

Correct Answer & Explanation

. Biceps tenodesis


Explanation

In patients over age 40, biceps tenodesis provides more predictable pain relief and functional improvement for Type II SLAP tears compared to arthroscopic SLAP repair, which carries a higher rate of stiffness in this age group.

Question 5233

Topic: Shoulder & Hip Sports

A 45-year-old man presents with chronic shoulder pain and stiffness after a seizure 6 weeks ago. Physical examination reveals an inability to externally rotate the shoulder beyond neutral. An axillary radiograph shows a defect on the anteromedial humeral head engaging the posterior glenoid. The defect involves 30% of the articular surface. What is the most appropriate surgical management?

. Closed reduction and spica cast
. Open reduction and subscapularis transfer (McLaughlin procedure)
. Arthroscopic Bankart repair
. Anatomic total shoulder arthroplasty
. Latarjet procedure

Correct Answer & Explanation

. Open reduction and subscapularis transfer (McLaughlin procedure)


Explanation

The patient has a missed posterior shoulder dislocation with a reverse Hill-Sachs lesion. For defects involving 25-40% of the articular surface, transfer of the subscapularis or lesser tuberosity into the defect is recommended.

Question 5234

Topic: 5. Sports Medicine

A 22-year-old elite baseball pitcher presents with vague anterior shoulder pain and a subjective "dead arm" feeling during the late cocking phase of throwing. MRI arthrogram reveals a type II SLAP tear. Nonoperative management has failed. What is the most appropriate surgical treatment?

. Biceps tenotomy
. Biceps tenodesis
. Arthroscopic SLAP repair
. Anterior capsulolabral reconstruction
. Coracoid transfer

Correct Answer & Explanation

. Arthroscopic SLAP repair


Explanation

In a young, elite overhead athlete with a symptomatic type II SLAP tear failing conservative management, arthroscopic SLAP repair is the procedure of choice. Biceps tenodesis is generally preferred for older or non-overhead athletes.

Question 5235

Topic: Shoulder & Hip Sports

A 28-year-old professional volleyball player presents with insidious onset of poorly localized posterior shoulder pain and weakness in external rotation. Examination reveals isolated atrophy of the infraspinatus. MRI demonstrates a paralabral cyst in the spinoglenoid notch. Which labral tear is most commonly associated with this pathology?

. Anterior Bankart tear
. Posterior labral tear
. Superior labral anterior-to-posterior (SLAP) tear
. Inferior labral tear
. Kim lesion

Correct Answer & Explanation

. Posterior labral tear


Explanation

Paralabral cysts in the spinoglenoid notch cause isolated compression of the suprascapular nerve branch to the infraspinatus. These cysts are most commonly associated with posterior labral tears.

Question 5236

Topic: 5. Sports Medicine
A 24-year-old professional hockey player sustains a direct blow to the point of his shoulder. Radiographs demonstrate 120% superior displacement of the distal clavicle relative to the acromion, and it is reducible on exam. What is the most appropriate management?
. Sling immobilization for 1-2 weeks followed by physical therapy
. Immediate open reduction and rigid plate fixation
. Distal clavicle excision
. Weaver-Dunn procedure
. Coracoclavicular ligament reconstruction with allograft

Correct Answer & Explanation

. Sling immobilization for 1-2 weeks followed by physical therapy


Explanation

This describes a Type III acromioclavicular (AC) joint separation. The initial treatment for most Type III injuries, even in high-level contact athletes, is nonoperative management.

Question 5237

Topic: Shoulder & Hip Sports

A 55-year-old manual laborer presents with chronic, severe shoulder weakness. He has an intact subscapularis, but MRI shows a massive, retracted, and fatty-infiltrated tear of the supraspinatus and infraspinatus (Goutallier stage 4). He has no glenohumeral arthritis. Which of the following is the most appropriate surgical option?

. Arthroscopic primary repair
. Latissimus dorsi tendon transfer
. Pectoralis major tendon transfer
. Total shoulder arthroplasty
. Superior capsular reconstruction with subscapularis release

Correct Answer & Explanation

. Latissimus dorsi tendon transfer


Explanation

For a young or active patient with an irreparable posterosuperior rotator cuff tear without arthritis and an intact subscapularis, a latissimus dorsi tendon transfer is an appropriate salvage procedure.

Question 5238

Topic: Shoulder & Hip Sports

A 21-year-old rugby player has recurrent anterior shoulder dislocations. Imaging reveals a 25% anterior glenoid bone loss and an engaging Hill-Sachs lesion. He undergoes a Latarjet procedure. Which structure is carefully preserved and utilized to create a "sling" effect during this procedure?

. Pectoralis minor
. Coracoacromial ligament
. Conjoint tendon
. Long head of the biceps
. Subscapularis upper third

Correct Answer & Explanation

. Conjoint tendon


Explanation

The Latarjet procedure involves transferring the coracoid process with the attached conjoint tendon through a split in the subscapularis. The conjoint tendon acts as a dynamic sling to prevent anterior translation of the humerus.

Question 5239

Topic: Shoulder & Hip Sports

A 25-year-old professional tennis player presents with posterior shoulder pain during the cocking phase of serving. Exam shows a positive relocation test and glenohumeral internal rotation deficit (GIRD) of 25 degrees compared to the contralateral side. What is the primary pathophysiologic mechanism of his shoulder pain?

. Compression of the suprascapular nerve
. Impingement of the undersurface of the rotator cuff against the posterosuperior glenoid
. Subacromial impingement of the bursal surface of the rotator cuff
. Traction injury to the long thoracic nerve
. Tear of the inferior glenohumeral ligament

Correct Answer & Explanation

. Impingement of the undersurface of the rotator cuff against the posterosuperior glenoid


Explanation

Internal impingement involves the pathologic contact of the articular surface of the supraspinatus and infraspinatus tendons against the posterosuperior glenoid and labrum during extreme abduction and external rotation.

Question 5240

Topic: Shoulder & Hip Sports

A 42-year-old man presents with a locked posterior shoulder dislocation after a seizure. CT scan reveals an anteromedial humeral head defect (reverse Hill-Sachs lesion) involving 30% of the articular surface. Which of the following is the most appropriate surgical management?

. Closed reduction and spica cast immobilization
. Arthroscopic Bankart repair alone
. Transfer of the lesser tuberosity into the defect (Modified McLaughlin procedure)
. Total shoulder arthroplasty
. Osteochondral allograft reconstruction

Correct Answer & Explanation

. Transfer of the lesser tuberosity into the defect (Modified McLaughlin procedure)


Explanation

For reverse Hill-Sachs lesions involving 20% to 40% of the articular surface, transferring the lesser tuberosity and subscapularis tendon into the defect (Modified McLaughlin) prevents engagement. Defects >40% typically require arthroplasty.
