This practice set contains high-yield board review questions covering key concepts in Shoulder & Hip Sports. Each clinical scenario is designed to test your diagnostic and management skills relevant to this subspecialty.
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?
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?
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?
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?
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?
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?
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?
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?
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?
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?
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?
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?
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?
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?
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?
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?
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?
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?
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?
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?
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.
