Shoulder & Hip Sports MCQs

A 22-year-old elite hockey player presents with insidious onset right groin pain that is exacerbated by prolonged sitting and deep squatting. Physical examination reveals a positive anterior impingement test (FADIR). Radiographs demonstrate an alpha angle of 65 degrees and normal acetabular version. If left untreated, the intra-articular pathology most characteristic of this specific morphology will primarily result in damage to which of the following structures?

A 24-year-old professional hockey player presents with a gradual onset of anterior groin pain exacerbated by hip flexion and internal rotation.

Radiographs show a prominent osseous bump at the anterolateral femoral head-neck junction and an alpha angle of 65 degrees. What pattern of chondral damage is most classically associated with this specific deformity?

A 26-year-old male collegiate hockey player presents with chronic anterior groin pain that is exacerbated by sitting in low chairs. Physical examination reveals a positive flexion, adduction, and internal rotation (FADIR) test. Radiographs demonstrate an alpha angle of 72 degrees on the lateral view with no evidence of acetabular retroversion. What is the primary pathophysiologic mechanism of cartilage damage in this condition?

A 24-year-old male hockey player presents with chronic groin pain exacerbated by hip flexion and internal rotation. Imaging reveals a prominent alpha angle of 75 degrees and a normal lateral center-edge angle. Which of the following best describes the primary pathomechanics of his articular cartilage injury?

During arthroscopic management of Femoroacetabular Impingement (FAI) for a symptomatic Cam lesion, the surgeon performs an osteochondroplasty at the femoral head-neck junction. Extending the resection too far posterosuperiorly places which of the following anatomic structures at the highest risk of iatrogenic injury?

A 25-year-old male hockey player presents with chronic groin pain exacerbated by hip flexion and internal rotation. An AP pelvis radiograph demonstrates a "crossover sign" and a prominent ischial spine. These radiographic findings are most indicative of which of the following pathomorphologies?

Which of the following radiographic parameters is most characteristic of Pincer-type femoroacetabular impingement (FAI)?

A 24-year-old rugby player has recurrent anterior shoulder instability. CT shows 25% anterior glenoid bone loss and an engaging Hill-Sachs lesion. What is the most appropriate surgical treatment?

A 55-year-old man presents with anterior shoulder pain and weakness following a fall. Physical examination reveals increased passive external rotation compared to the contralateral side, and a positive belly-press test. Which tendon is most likely injured?

A 28-year-old volleyball player complains of vague posterior shoulder pain and weakness. Exam reveals isolated atrophy of the infraspinatus with preserved supraspinatus muscle bulk. Where is the most likely site of nerve compression?

A 22-year-old baseball pitcher has posterior shoulder pain during the late cocking phase of throwing. He has a loss of internal rotation (GIRD) of 25 degrees. MRI shows articular-sided partial-thickness tearing of the posterior supraspinatus. What is the most likely diagnosis?

A 65-year-old man who underwent anatomic total shoulder arthroplasty 5 years ago presents with progressively worsening shoulder pain.

The "rocking horse" phenomenon in anatomic total shoulder arthroplasty, which leads to glenoid loosening, is most directly caused by:

A 42-year-old man suddenly developed excruciating, unprovoked right shoulder pain 2 weeks ago that lasted for several days. As the pain subsided, he noted profound weakness in shoulder abduction and external rotation. EMG shows active denervation of the supraspinatus and deltoid. What is the most likely diagnosis?

A 30-year-old male volleyball player presents with painless weakness in external rotation of his dominant shoulder. Abduction strength is normal. An MRI confirms a paralabral cyst in the spinoglenoid notch. Which of the following associated pathologies is most likely the root cause of this cyst?

During the evaluation of a patient with a suspected rotator cuff tear, which of the following isolated physical examination findings is most specific for a complete tear of the subscapularis tendon?

A 24-year-old rugby player undergoes an open Latarjet procedure for recurrent anterior shoulder instability associated with 25% glenoid bone loss. Postoperatively, he exhibits profound weakness in elbow flexion and decreased sensation over the lateral aspect of the forearm. Which nerve was most likely injured during the coracoid transfer?

The rotator interval is a critical anatomic space in the shoulder that is often targeted in capsular release or plication. Which of the following structures are contained within this interval?

A 24-year-old baseball pitcher presents with posterior shoulder pain during the late cocking phase of throwing. He has a 20-degree loss of internal rotation compared to the contralateral side. MRI shows articular-sided partial tearing of the posterior supraspinatus and posterosuperior labral fraying.

What is the primary underlying pathophysiology?

A 35-year-old male presents with recurrent anterior shoulder instability. A CT scan with 3D reconstruction demonstrates 25% anterior glenoid bone loss.

Which of the following procedures is most appropriate?

A 42-year-old construction worker sustained an electrical shock and was diagnosed with a locked posterior shoulder dislocation. CT scan shows an anteromedial humeral head impaction fracture (reverse Hill-Sachs lesion) involving 30% of the articular surface.

The duration of dislocation is 2 weeks. What is the recommended treatment?
