Shoulder & Hip Sports MCQs

On a standard AP radiograph of a patient with a suspected posterior dislocation, a dense vertical line is noted on the medial aspect of the humeral head. This 'trough line' represents which of the following pathologic findings?

The classic (original) McLaughlin procedure, utilized for the treatment of moderate-sized anteromedial humeral head defects, involves the transfer of which of the following structures into the bony defect?

Bilateral posterior shoulder dislocations are a rare clinical entity but are highly specific to a particular mechanism of injury. Which of the following etiologies is most classically associated with simultaneous bilateral posterior dislocations?

A 32-year-old male sustains a locked posterior shoulder dislocation during a seizure. CT imaging reveals an anteromedial humeral head impaction fracture involving 35% of the articular surface. The glenoid is completely intact. Which of the following is the most appropriate surgical management?

A 26-year-old male volleyball player presents with insidious onset posterior shoulder pain and weakness in external rotation. MRI reveals a posterosuperior labral tear with a multiloculated cyst occupying the spinoglenoid notch. Which of the following physical examination findings is most likely present?

A 15-year-old female presents with the ability to spontaneously dislocate her shoulder posteriorly without pain. She demonstrates this by bringing her arm into elevation and internal rotation, then easily reduces it. She has no history of trauma. What is the most appropriate initial management?

A 25-year-old rugby player has recurrent posterior shoulder instability despite a previous arthroscopic posterior labral repair. Preoperative CT imaging reveals excessive glenoid retroversion of 22 degrees and 25% posterior glenoid bone loss. What is the most appropriate surgical intervention?

During a physical examination for posterior instability, the examiner performs the Kim test to identify a concealed posteroinferior labral tear. Which combination of joint positions and forces best isolates the posteroinferior labrum during this specific test?

A 28-year-old male undergoes an open posterior capsulorrhaphy for refractory posterior shoulder instability. Postoperatively, he develops a severe limitation in forward elevation, cross-body adduction, and internal rotation. What is the most likely iatrogenic cause of this complication?

When performing an arthroscopic posterior Bankart repair, the surgeon needs an optimal trajectory to place suture anchors at the 7 o'clock position in a right shoulder. Which accessory portal is most commonly utilized to achieve the best approach angle for this region?

A 27-year-old military paratrooper suffers from recurrent posterior shoulder subluxations. Imaging demonstrates a posterior labral tear, 5% posterior glenoid bone loss, and 5 degrees of glenoid retroversion. After failing 6 months of non-operative management, what is the surgical treatment of choice?

Which imaging modality and specific measurement technique represent the gold standard for quantifying glenoid retroversion in a patient evaluated for recurrent posterior shoulder instability?

The Neer modification of the classic McLaughlin procedure is commonly used for chronic posterior shoulder dislocations with large anteromedial humeral head defects. This modification specifically involves the transfer of which anatomical structure into the defect?

A 30-year-old male undergoes an open posterior capsulorrhaphy for recurrent posterior shoulder instability. Postoperatively, he complains of significant restriction in his range of motion, significantly affecting his activities of daily living. Overtightening of the posterior capsule is most likely to restrict which of the following motions?

A 55-year-old male presents with chronic right shoulder pain 4 months after a prolonged seizure. Clinical examination reveals a rigid block to external rotation. Radiographs confirm a locked posterior dislocation. Which of the following findings is the strongest indication for proceeding with shoulder arthroplasty rather than a joint-preserving reconstruction?

A surgeon is performing an arthroscopic posterior stabilization for a reverse Bankart lesion. To achieve the most optimal trajectory for suture anchor insertion into the posteroinferior glenoid rim (7 o'clock to 9 o'clock positions), which of the following arthroscopic portals should be utilized?

A 6-year-old child with a history of an obstetric brachial plexus palsy (Erb's palsy) presents with an internal rotation contracture of the shoulder. Imaging reveals progressive posterior subluxation of the humeral head and early glenoid dysplasia. What is the most critical initial surgical intervention to halt the progression of this joint deformity?

A 42-year-old male undergoes surgery for a locked posterior shoulder dislocation with a 30% anteromedial humeral head defect. The surgeon performs an open reduction and transfers both the subscapularis tendon and the lesser tuberosity into the articular defect. Which eponymous procedure does this describe?
