Shoulder & Hip Sports MCQs

A 55-year-old male carpenter presents with a 3-month history of right shoulder pain and weakness, particularly when reaching overhead. He has a positive Jobe's (empty can) test and a positive drop arm test. MRI confirms a full-thickness tear of the supraspinatus tendon with 2 cm of retraction. Which of the following biomechanical consequences is most likely to occur if this tear is left untreated and progresses to massive size?

A 55-year-old male carpenter presents with chronic right shoulder pain and weakness, particularly when lifting objects above his head. Physical examination reveals a positive Jobe's (empty can) test and weakness in active shoulder abduction. Which of the following muscles is most likely affected?

A 55-year-old male undergoes arthroscopic rotator cuff repair for a massive tear involving the supraspinatus and infraspinatus tendons. During the procedure, the surgeon must be careful to avoid injury to the suprascapular nerve. At which anatomical location is the suprascapular nerve most vulnerable to injury during medial mobilization of a retracted infraspinatus tendon?

A 55-year-old male presents with right shoulder pain and weakness after lifting a heavy box. Physical examination reveals a positive drop arm test and weakness with resisted shoulder abduction in the scapular plane. MRI confirms a full-thickness tear of the most commonly injured rotator cuff tendon. Where does this specific tendon insert anatomically?

A 55-year-old male presents with chronic shoulder pain and weakness in abduction and external rotation. MRI confirms a massive, retracted tear of the supraspinatus and infraspinatus tendons. Which of the following nerves provides the primary motor innervation to both of these affected muscles, and through which anatomical structure does it pass to reach the infraspinatus?

A 22-year-old collegiate offensive lineman presents with recurrent posterior shoulder instability. He has not had any frank dislocations but experiences subluxations when blocking. He wishes to pursue non-operative management. A physical therapy program is initiated. Which of the following muscle groups should be the primary focus of his strengthening program?

A 35-year-old male with a history of poorly controlled epilepsy presents to the clinic with chronic right shoulder pain and limited range of motion following a seizure 3 weeks ago. He is unable to externally rotate his right shoulder past neutral. An AP radiograph of the shoulder reveals a symmetric appearance of the humeral head with loss of the normal half-moon overlap. Which of the following additional radiographic findings is most specific for his suspected diagnosis?

A 40-year-old male presents with a chronic, locked posterior shoulder dislocation that occurred during an electrocution injury 4 weeks ago. A CT scan reveals an anteromedial humeral head impaction fracture (reverse Hill-Sachs lesion) involving 35% of the articular surface. Which of the following surgical interventions is most appropriate?

A 21-year-old rugby player sustains a posterior shoulder dislocation after falling on an outstretched, internally rotated arm. Following closed reduction, an MRI is obtained. It reveals a detachment of the posterior labrum and posterior capsule from the glenoid rim. What is the eponymous name for this specific lesion?

Posterior shoulder dislocations account for approximately 2-5% of all shoulder dislocations. While trauma is a common cause, non-traumatic etiologies are classically associated with this injury due to intense, uncoordinated muscle contractions. Which of the following muscles' overpowering force is primarily responsible for posterior dislocation during a seizure?

A surgeon is performing an open posterior stabilization for recurrent posterior shoulder instability. The classic posterior approach to the shoulder utilizes an internervous plane. Which of the following describes the correct internervous plane for this approach?

A 22-year-old collegiate offensive lineman presents with recurrent posterior shoulder instability. He has not experienced any frank dislocations but reports a sensation of the shoulder 'slipping out' posteriorly when blocking. MRI shows a nondisplaced posterior labral tear without significant glenoid bone loss. He elects to undergo conservative management. A targeted physical therapy program should primarily emphasize strengthening of which of the following muscle groups?

A 40-year-old male presents with a locked posterior shoulder dislocation that occurred 3 weeks ago following an unrecognized seizure. CT scan demonstrates a reverse Hill-Sachs lesion involving 35% of the articular surface. Which of the following is the most appropriate surgical management for this osseous defect?

A surgeon is performing an open posterior stabilization for recurrent posterior shoulder instability. The classic posterior approach to the shoulder utilizes an internervous plane between which of the following two muscles?

During the physical examination of a 19-year-old male with suspected posterior shoulder instability, the examiner places the patient's arm in 90 degrees of abduction and internal rotation. The examiner then applies an axial load to the humerus while horizontally adducting the arm. A sudden clunk is felt as the humeral head subluxates posteriorly. As the arm is returned to the starting position, a second clunk is felt. This clinical test is known as the:

A 28-year-old male presents to the clinic with a history of recurrent posterior shoulder subluxations. To best evaluate for the presence of a reverse Hill-Sachs lesion on plain radiography, which of the following views is most appropriate?

A 22-year-old collegiate offensive lineman presents with a history of recurrent posterior shoulder instability. He has not had any frank dislocations but experiences pain and a sensation of subluxation when his arm is forward flexed, adducted, and internally rotated during blocking maneuvers. He is prescribed a comprehensive physical therapy program. Which of the following muscles should be the primary focus of strengthening to dynamically stabilize the glenohumeral joint against posterior translation?

A 19-year-old male weightlifter complains of vague posterior shoulder pain that worsens during the descent phase of the bench press. You suspect underlying posterior shoulder instability and a possible labral tear. Which of the following physical examination maneuvers is most specific for detecting a posteroinferior labral tear?

A 40-year-old male presents with a locked posterior shoulder dislocation that occurred 3 weeks ago following an electrical shock. Computed tomography (CT) imaging reveals an anteromedial humeral head defect involving 35% of the articular surface. Which of the following is the most appropriate surgical management to prevent recurrent instability?
