Shoulder & Hip Sports MCQs

A 55-year-old man presents with anterior shoulder pain following a fall. Physical examination reveals a positive lift-off test, a positive belly-press test, and passively increased external rotation compared to the contralateral side. What is the most likely diagnosis?

A 45-year-old construction worker with chronic anterior shoulder pain exhibits a positive Speed's test. MRI reveals a Type II SLAP lesion with significant macroscopic degeneration of the biceps anchor. What is the most reliable surgical option?

A 22-year-old male presents with recurrent anterior shoulder instability. A pre-operative 3D CT scan demonstrates 28% anterior glenoid bone loss. Which of the following procedures provides the most reliable long-term stability?

During arthroscopic repair of a posterior SLAP tear, the surgeon must be cautious when placing suture anchors or drilling into the posterior glenoid neck. Penetrating the posterior glenoid neck medially by more than what distance puts the suprascapular nerve at significant risk?

A 22-year-old rugby player presents with recurrent anterior shoulder instability. A CT scan of the shoulder reveals 25% anterior glenoid bone loss. The surgeon plans a Latarjet procedure. This procedure provides dynamic anterior stability through a 'sling effect' primarily involving the interaction between the lower subscapularis and which of the following structures?

A 28-year-old volleyball player presents with isolated weakness in external rotation of the shoulder. MRI reveals a paralabral cyst. Compression of the involved nerve at the spinoglenoid notch will selectively denervate which of the following muscles?

A surgeon is executing a posterior approach to the shoulder. The superficial dissection interval is between the deltoid and the teres minor. The deep internervous plane separates which two muscles?

A 30-year-old baseball pitcher presents with vague posterior shoulder pain and deltoid weakness. MRI reveals isolated atrophy of the teres minor. Which of the following anatomic boundaries defines the quadrilateral space through which the affected nerve passes?

A 45-year-old patient presents postoperatively with profound isolated weakness in shoulder external rotation following a massive rotator cuff repair. Electromyography reveals denervation of the infraspinatus with normal supraspinatus function. At what anatomical site is the suprascapular nerve most likely entrapped?

A patient has isolated weakness in external rotation of the shoulder but demonstrates normal active abduction. An MRI reveals a paralabral cyst. In which anatomical location is the cyst most likely compressing the affected nerve?

A 32-year-old volleyball player presents with isolated weakness in external rotation of the shoulder. MRI reveals a paralabral cyst compressing a nerve at the spinoglenoid notch. Which physical examination finding corresponds to this specific level of entrapment?

A 50-year-old woman undergoes arthroscopic shoulder stabilization for recurrent instability. The surgeon carefully evaluates and addresses pathology within the rotator interval. Which of the following structures is considered a standard normal content of the rotator interval?

During a surgical dislocation of the hip for femoroacetabular impingement, the surgeon must preserve the primary blood supply to the adult femoral head. Which of the following vessels is the most critical to protect?

A professional volleyball player presents with isolated atrophy and weakness of the infraspinatus muscle, with normal supraspinatus strength and bulk. Where is the most likely site of nerve compression?

A patient presents with isolated weakness of the infraspinatus muscle but normal supraspinatus strength. The suprascapular nerve is most likely compressed at which of the following anatomic locations?

A pitcher complains of right shoulder pain and weakness with overhead activities. Examination reveals isolated wasting of the supraspinatus and infraspinatus. Entrapment of the affected nerve is most likely to occur at which of the following anatomical sites?

A surgeon is performing an open anterior shoulder stabilization and identifies the rotator interval. Which of the following structures is NOT considered a normal anatomical border or content of the rotator interval?

Figure 28 shows an arthroscopic view of a right shoulder in the lateral position through a posterior portal. What is the area between structure B (biceps) and SS (subscapularis tendon)?

A 28-year-old volleyball player presents with painless weakness of shoulder external rotation. Atrophy is noted in the infraspinatus fossa, while the supraspinatus fossa is normal. Where is the most likely site of nerve compression?

The rotator interval of the shoulder is a triangular anatomical space. What structures form its superior and inferior borders?
