Question 2121

Topic: Shoulder & Hip Sports

A 22-year-old male rugby player presents with recurrent anterior shoulder instability. A CT scan with 3D reconstruction reveals 23% anterior glenoid bone loss. Which of the following surgical procedures is most appropriate?

. Arthroscopic Bankart repair
. Arthroscopic Bankart repair with remplissage
. Open Bankart repair
. Latarjet procedure
. Arthroscopic labral repair with superior capsular shift

Correct Answer & Explanation

. Latarjet procedure


Explanation

In a collision athlete with significant glenoid bone loss (>20-25%), a bony augmentation procedure like the Latarjet is the standard of care to restore anterior stability. Arthroscopic Bankart repair has an unacceptably high failure rate in this setting.

Question 2122

Topic: Shoulder & Hip Sports

A 28-year-old male volleyball player presents with insidious onset of vague posterior shoulder pain and weakness in external rotation. MRI reveals a paralabral cyst at the spinoglenoid notch. Which of the following is the most likely physical exam finding?

. Atrophy of both the supraspinatus and infraspinatus
. Isolated atrophy of the infraspinatus
. Isolated atrophy of the supraspinatus
. Scapular winging with forward flexion
. Loss of active forward elevation

Correct Answer & Explanation

. Isolated atrophy of the infraspinatus


Explanation

Entrapment of the suprascapular nerve at the spinoglenoid notch affects only the infraspinatus muscle, leading to isolated atrophy and weakness in external rotation. Compression at the suprascapular notch would affect both the supraspinatus and infraspinatus.

Question 2123

Topic: Shoulder & Hip Sports

A 32-year-old male weightlifter feels a "pop" in his anterior chest wall while performing a bench press. Examination reveals loss of the anterior axillary fold and weakness in internal rotation and adduction. MRI confirms a complete tear of the pectoralis major at its humeral insertion. What is the recommended treatment?

. Physical therapy focusing on rotator cuff strengthening
. Nonoperative management with a sling for 6 weeks
. Early surgical repair
. Delayed surgical repair after 3 months
. Local corticosteroid injection

Correct Answer & Explanation

. Early surgical repair


Explanation

Acute surgical repair of complete pectoralis major ruptures at the humeral insertion in active individuals yields superior cosmetic and functional results compared to nonoperative management or delayed repair.

Question 2124

Topic: Shoulder & Hip Sports

A 45-year-old male sustains a traumatic anterior shoulder dislocation. After reduction, he has persistent weakness in internal rotation and increased passive external rotation compared to the contralateral side. The bear-hug and belly-press tests are positive. What is the most likely diagnosis?

. Supraspinatus tear
. Infraspinatus tear
. Subscapularis tear
. Teres minor tear
. Bankart lesion

Correct Answer & Explanation

. Subscapularis tear


Explanation

A traumatic anterior shoulder dislocation in patients over 40 can be associated with a rotator cuff tear. Weakness in internal rotation, increased passive external rotation, and positive bear-hug and belly-press tests specifically indicate a subscapularis tear.

Question 2125

Topic: Shoulder & Hip Sports
A 50-year-old male presents with anterior shoulder pain exacerbated by overhead activities. Physical exam shows a positive Neer and Hawkins test. Radiographs demonstrate a type III acromion and subacromial spurring. MRI shows tendinosis of the supraspinatus without a full-thickness tear. After 6 months of failed conservative treatment, what is the best surgical option?
. Arthroscopic subacromial decompression and acromioplasty
. Arthroscopic rotator cuff repair
. Open acromioplasty
. Biceps tenodesis
. Superior capsular reconstruction

Correct Answer & Explanation

. Arthroscopic subacromial decompression and acromioplasty


Explanation

For patients with subacromial impingement and a type III (hooked) acromion who fail comprehensive conservative treatment, arthroscopic subacromial decompression and acromioplasty is the accepted surgical procedure.

Question 2126

Topic: Shoulder & Hip Sports

A 22-year-old competitive rugby player sustains his third anterior shoulder dislocation. Imaging reveals an engaging Hill-Sachs lesion and 25% anterior glenoid bone loss. Which of the following is the most appropriate surgical management?

. Arthroscopic Bankart repair
. Arthroscopic Remplissage and Bankart repair
. Latarjet procedure
. Open capsular shift
. Arthroscopic labral repair with bioabsorbable anchors

Correct Answer & Explanation

. Latarjet procedure


Explanation

In a contact athlete with significant anterior glenoid bone loss (>20%) and an engaging Hill-Sachs lesion, a bony augmentation procedure like the Latarjet is indicated. Soft-tissue only repairs in this setting carry an unacceptably high recurrence rate.

Question 2127

Topic: Shoulder & Hip Sports

A 28-year-old elite volleyball player presents with painless weakness in her dominant shoulder. Examination reveals isolated atrophy of the infraspinatus muscle. MRI shows a paralabral cyst. Where is the most likely location of the nerve compression?

. Suprascapular notch
. Quadrilateral space
. Spinoglenoid notch
. Spiral groove
. Cubital tunnel

Correct Answer & Explanation

. Spinoglenoid notch


Explanation

Compression of the suprascapular nerve at the spinoglenoid notch typically results in isolated weakness and atrophy of the infraspinatus. Compression more proximally at the suprascapular notch would affect both the supraspinatus and infraspinatus.

Question 2128

Topic: Shoulder & Hip Sports

A 68-year-old man presents with a massive, retracted rotator cuff tear involving the supraspinatus and entire infraspinatus, with Goutallier stage 4 fatty infiltration. He has preserved active forward elevation to 140 degrees but lacks active external rotation. Radiographs show no glenohumeral arthritis. Which procedure is most appropriate?

. Arthroscopic partial repair
. Superior capsule reconstruction
. Latissimus dorsi tendon transfer
. Reverse total shoulder arthroplasty
. Pectoralis major tendon transfer

Correct Answer & Explanation

. Latissimus dorsi tendon transfer


Explanation

In a younger or active patient with an irreparable posterosuperior cuff tear, absent arthritis, preserved elevation but loss of active external rotation, a latissimus dorsi or lower trapezius tendon transfer is indicated. Superior capsule reconstruction focuses on superior translation, not primarily restoring external rotation.

Question 2129

Topic: Shoulder & Hip Sports

A 40-year-old man presents with shoulder pain after a generalized seizure. He holds his arm adducted and internally rotated. He cannot actively or passively externally rotate the shoulder. Radiographs show a "lightbulb" sign. Which associated lesion is most likely present?

. Engaging Hill-Sachs lesion
. Reverse Hill-Sachs lesion
. Bankart lesion
. Superior labral tear
. Coracoid fracture

Correct Answer & Explanation

. Reverse Hill-Sachs lesion


Explanation

This patient has a posterior shoulder dislocation, commonly occurring after seizures or electrical shock. It is frequently associated with a reverse Hill-Sachs lesion (impaction fracture of the anteromedial humeral head) and a reverse Bankart lesion.

Question 2130

Topic: Shoulder & Hip Sports

A 30-year-old competitive tennis player complains of posterior shoulder pain and numbness over the lateral deltoid. Examination shows point tenderness at the posterior joint line and weakness in external rotation. Arteriogram reveals occlusion of the posterior humeral circumflex artery with shoulder abduction. What are the boundaries of the space involved?

. Teres minor, teres major, long head of triceps, humeral shaft
. Teres minor, teres major, short head of biceps, humeral shaft
. Supraspinatus, teres minor, long head of triceps, glenoid
. Teres major, latissimus dorsi, long head of triceps, humerus
. Subscapularis, teres major, coracobrachialis, short head of biceps

Correct Answer & Explanation

. Teres minor, teres major, long head of triceps, humeral shaft


Explanation

Quadrilateral space syndrome involves compression of the axillary nerve and posterior humeral circumflex artery. The boundaries are the teres minor (superior), teres major (inferior), long head of the triceps (medial), and humeral shaft (lateral).

Question 2131

Topic: Shoulder & Hip Sports

The "terrible triad of the shoulder" typically refers to an anterior shoulder dislocation accompanied by which two additional injuries?

. Rotator cuff tear and brachial plexus injury
. Bankart lesion and Hill-Sachs lesion
. Coracoid fracture and acromion fracture
. Greater tuberosity fracture and biceps rupture
. Clavicle fracture and scapular body fracture

Correct Answer & Explanation

. Rotator cuff tear and brachial plexus injury


Explanation

The classic "terrible triad of the shoulder" consists of an anterior shoulder dislocation, a rotator cuff tear, and a neurologic injury (often involving the brachial plexus or axillary nerve). This pattern usually occurs in older patients.

Question 2132

Topic: Shoulder & Hip Sports

During the physical examination of a patient with suspected rotator cuff pathology, the examiner places the patient's hand behind their back at the lumbar level and asks them to lift the hand away from the back. This test is primarily evaluating the integrity of which structure?

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

Correct Answer & Explanation

. Subscapularis


Explanation

The described maneuver is the "Gerber lift-off test," which isolates and tests the strength and integrity of the subscapularis muscle. The belly-press and bear-hug tests are also specific for subscapularis pathology.

Question 2133

Topic: Shoulder & Hip Sports

A 21-year-old collegiate rugby player with recurrent anterior shoulder instability undergoes a preoperative CT scan. The scan demonstrates a 28% anterior glenoid bone loss. Which of the following is the most appropriate surgical intervention?

. Arthroscopic Bankart repair
. Arthroscopic remplissage
. Open Bankart repair with inferior capsular shift
. Coracoid transfer (Latarjet procedure)
. Proximal humerus derotational osteotomy

Correct Answer & Explanation

. Coracoid transfer (Latarjet procedure)


Explanation

In young, high-demand athletes with recurrent anterior instability and critical glenoid bone loss (typically > 20-25%), a bony augmentation procedure like the Latarjet is indicated to restore glenohumeral stability. Soft tissue repair alone has an unacceptably high failure rate.

Question 2134

Topic: Shoulder & Hip Sports

A 55-year-old laborer presents with an irreparable posterosuperior rotator cuff tear. He lacks active external rotation and forward elevation but has an intact subscapularis. Which of the following tendon transfers is most appropriate to restore external rotation?

. Pectoralis major
. Latissimus dorsi
. Lower trapezius
. Levator scapulae
. Pectoralis minor

Correct Answer & Explanation

. Lower trapezius


Explanation

Lower trapezius and latissimus dorsi transfers are used for irreparable posterosuperior tears. The lower trapezius transfer more closely replicates the natural force vector of the infraspinatus and is increasingly favored for restoring external rotation.

Question 2135

Topic: Shoulder & Hip Sports

A 22-year-old collegiate baseball pitcher presents with vague posterior shoulder pain. Physical examination shows a Glenohumeral Internal Rotation Deficit (GIRD) of 25 degrees compared to the contralateral side. The primary anatomic structure responsible for this finding is:

. Contracture of the anteroinferior capsule
. Hypertrophy of the subscapularis
. Contracture of the posteroinferior capsule
. Laxity of the superior glenohumeral ligament
. Hyperlaxity of the coracohumeral ligament

Correct Answer & Explanation

. Contracture of the posteroinferior capsule


Explanation

GIRD in throwing athletes is primarily caused by contracture and thickening of the posteroinferior capsule. This occurs as a maladaptive response to repetitive eccentric loading during the deceleration phase of throwing.

Question 2136

Topic: Shoulder & Hip Sports

A 50-year-old male presents with anterior shoulder pain after a fall. He has a positive "belly-press" test. Which of the following physical examination findings would also most likely be positive in this patient?

. Jobe's test
. Bear hug test
. Hornblower's sign
. O'Brien's active compression test
. External rotation lag sign

Correct Answer & Explanation

. Bear hug test


Explanation

The belly-press test and the bear hug test are both highly specific maneuvers for evaluating the integrity of the subscapularis tendon. Hornblower's sign and the external rotation lag sign evaluate the posterosuperior rotator cuff.

Question 2137

Topic: Shoulder & Hip Sports

A 29-year-old professional volleyball player presents with painless weakness of external rotation of the shoulder. Examination reveals isolated atrophy of the infraspinatus fossa. The supraspinatus strength and muscle bulk are normal. The most likely site of nerve compression is:

. Suprascapular notch
. Spinoglenoid notch
. Quadrilateral space
. Triangular interval
. Thoracic outlet

Correct Answer & Explanation

. Spinoglenoid notch


Explanation

Compression of the suprascapular nerve at the spinoglenoid notch presents with isolated weakness and atrophy of the infraspinatus. Compression more proximally at the suprascapular notch affects both the supraspinatus and infraspinatus.

Question 2138

Topic: Shoulder & Hip Sports

A 22-year-old collegiate rugby player presents with recurrent anterior shoulder dislocations. Imaging reveals a 25% anterior glenoid bone loss defect. Which of the following is the most appropriate surgical intervention?

. Arthroscopic Bankart repair
. Open Bankart repair
. Latarjet procedure
. Arthroscopic Remplissage alone
. Arthroscopic capsular shift

Correct Answer & Explanation

. Latarjet procedure


Explanation

In collision athletes with critical anterior glenoid bone loss (greater than 20-25%), isolated soft tissue repairs have unacceptably high failure rates. The Latarjet procedure (coracoid transfer) is required to restore the articular arc and provide a triple blocking effect.

Question 2139

Topic: Shoulder & Hip Sports

A 48-year-old heavy laborer presents with deep anterior shoulder pain. MRI confirms an isolated Type II SLAP tear. Nonoperative management has failed after 6 months. What is the most appropriate surgical management?

. Arthroscopic SLAP repair
. Arthroscopic biceps tenodesis
. Arthroscopic biceps tenotomy
. Physical therapy focusing on internal rotation
. Subacromial decompression

Correct Answer & Explanation

. Arthroscopic biceps tenodesis


Explanation

For patients older than 40 with symptomatic Type II SLAP tears, biceps tenodesis is preferred over SLAP repair. This approach avoids the high rates of postoperative stiffness, persistent pain, and revision surgery associated with SLAP repairs in older patients.

Question 2140

Topic: Shoulder & Hip Sports

A 35-year-old elite volleyball player complains of vague posterior shoulder pain and isolated weakness in external rotation. Examination shows atrophy of the infraspinatus with a normal supraspinatus. Where is the most likely location of nerve entrapment?

. Suprascapular notch
. Spinoglenoid notch
. Quadrilateral space
. Spiral groove
. Posterior cervical triangle

Correct Answer & Explanation

. Spinoglenoid notch


Explanation

Entrapment of the suprascapular nerve at the spinoglenoid notch, often by a paralabral cyst, results in isolated denervation of the infraspinatus. Entrapment further proximal at the suprascapular notch would affect both the supraspinatus and infraspinatus muscles.
