Sample itemA 55-year-old diabetic woman has a painful stiff shoulder, with both active and passive movement restricted, especially external rotation. The radiograph is normal. What is the diagnosis?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. Adhesive capsulitis (frozen shoulder)
Adhesive capsulitis is a fibrotic contracture of the glenohumeral capsule, more common in diabetics and middle-aged women. Both active and passive range are limited, external rotation most, and the radiograph is normal. It usually resolves slowly over many months to a few years.
Option by option
A. Adhesive capsulitis (frozen shoulder) (correct)
Correct. Global restriction of active and passive motion with a normal radiograph is typical.
B. Glenohumeral osteoarthritis
Osteoarthritis would show joint space narrowing and osteophytes on the radiograph.
C. Full-thickness rotator cuff tear
A cuff tear causes weak active elevation but passive movement is usually preserved.
D. Posterior shoulder dislocation
Posterior dislocation follows trauma or seizures and is visible on imaging with fixed internal rotation.
