Shoulder & Hip Sports MCQs

A 30-year-old male volleyball player presents with isolated weakness in external rotation of his dominant shoulder. Forward elevation and internal rotation strength are normal. MRI reveals a paralabral cyst. At what anatomical location is this cyst most likely compressing the affected nerve?

Latissimus dorsi tendon transfer is occasionally considered for patients with massive, irreparable posterosuperior rotator cuff tears. Which of the following is generally considered an absolute contraindication for this procedure?

A 21-year-old collegiate linebacker undergoes arthroscopic stabilization for recurrent anterior shoulder instability. During diagnostic arthroscopy, the surgeon notes an avulsion of the anteroinferior capsulolabral complex from the glenoid rim. What is the classic eponym for this lesion?

An MRI of the shoulder reveals a paralabral cyst compressing the suprascapular nerve strictly at the spinoglenoid notch. Which physical exam finding is most likely to be isolated in this patient?

A 28-year-old volleyball player presents with insidious onset of posterior shoulder pain and weakness. Examination reveals isolated external rotation weakness with the arm at the side and visible atrophy of the infraspinatus. Supraspinatus strength is normal. Where is the most likely site of nerve compression?

A patient presents with weakness in shoulder abduction and external rotation following a traction injury. EMG reveals denervation isolated to the supraspinatus and infraspinatus muscles. Which of the following anatomic landmarks is the most frequent site of compression?

A 26-year-old professional baseball pitcher presents with isolated, painless weakness in external rotation of his throwing shoulder. Magnetic resonance imaging demonstrates isolated atrophy of the infraspinatus muscle. At which of the following anatomical locations is the affected nerve most likely compressed?

A 34-year-old professional volleyball player presents with insidious onset of right shoulder weakness. Examination reveals isolated atrophy of the infraspinatus with normal supraspinatus bulk and strength. Where is the most likely site of nerve compression?

A 25-year-old man sustains a severe traction injury to his shoulder, resulting in a disruption of the posterior cord of the brachial plexus. Which of the following muscles will most likely demonstrate profound weakness on clinical examination?

A 28-year-old elite volleyball player presents with isolated weakness of external rotation in his dominant shoulder. MRI reveals a paralabral cyst in the spinoglenoid notch. Which nerve is compressed, and which muscle(s) will demonstrate denervation changes?

A 28-year-old volleyball player presents with isolated weakness in external rotation of the shoulder with the arm at the side, but has normal abduction strength and no sensory deficits. An MRI reveals a paralabral cyst in the spinoglenoid notch. From which structural level of the brachial plexus does the affected nerve originate?

During a Latarjet procedure for recurrent anterior shoulder instability, the conjoined tendon is mobilized and retracted to gain exposure to the anterior glenoid. The surgeon must be mindful of the musculocutaneous nerve entering the coracobrachialis muscle. What is the typical distance from the tip of the coracoid process to the point where this nerve enters the muscle?

A professional volleyball player presents with isolated weakness of the infraspinatus muscle. MRI reveals a ganglion cyst compressing a nerve at the spinoglenoid notch. Which ligament forms the roof of this notch?

A patient presents with isolated weakness of external rotation of the shoulder with preserved abduction. At which of the following anatomical locations is nerve entrapment most likely occurring?

A professional volleyball player presents with isolated weakness in external rotation of the shoulder. Atrophy is noted in the infraspinatus fossa, while the supraspinatus is normal. Entrapment of the suprascapular nerve is suspected at which location?

A 24-year-old male sustains a posterior shoulder dislocation. After reduction, he exhibits numbness over the lateral aspect of his shoulder and weak shoulder abduction. The injured nerve exits the axilla through a space bounded by which of the following structures?

A professional volleyball player presents with isolated atrophy and weakness of the infraspinatus muscle. Supraspinatus strength and muscle bulk are entirely normal. Where is the most likely site of nerve entrapment?

A volleyball player presents with painless weakness in external rotation of the shoulder. Examination reveals atrophy isolated to the infraspinatus fossa. An MRI demonstrates a paralabral cyst. Where is the cyst most likely located to cause this specific presentation?

A 35-year-old professional volleyball player presents with painless shoulder weakness. Examination reveals isolated profound atrophy of the infraspinatus with completely preserved supraspinatus muscle bulk. Where is the most likely anatomic site of nerve entrapment?

A patient presents with vague posterior shoulder pain and isolated weakness of the teres minor and deltoid. MRI reveals a paralabral cyst compressing structures within the quadrilateral space. Which of the following correctly describes the anatomical borders of this space?
