MRI shoulder in a 30-year-old after anterior dislocation shows a compression fracture of the posterosuperior humeral head and anteroinferior glenoid bone loss. These are termed respectively:
- A Bankart lesion and Hill-Sachs lesion
- B HAGL lesion and Bennett lesion
- C Hill-Sachs lesion and Bankart lesion ✓
- D Superior labral tear (SLAP) and Buford complex
Explanation
Hill-Sachs lesion is the posterosuperior humeral head compression fracture from impaction against the anteroinferior glenoid rim during anterior dislocation. Bankart lesion is the anteroinferior glenoid labrum avulsion (bone Bankart = bone loss from glenoid). Together they constitute the primary lesions predisposing to recurrent anterior instability. HAGL is avulsion of the inferior glenohumeral ligament. SLAP is a superior labral lesion from traction/compression.
