Hill Sachs Lesion
- See Reverse Hill Sach Lesion:
- posterolateral humeral head indentation fracture is created occuring from anterior shoulder dislocation, as soft base of humeral
head impacts against relatively hard anterior glenoid;
- occurs in 35-40% of anterior dislocations & upto 80 % of recurrent dislocations;
- during shoulder arthroscopy this lesion is sometimes confused w/ the normal bare area of postero-inferior aspect of humeral head;
- it is noteworthy that the Hill sachs lesion occurs thru the cartilagenous surface of the humeral head and that often there will remain a
small island of cartilage located between the bare area and the Hill Sachs lesion;
- Hill Sachs Lesion may destabilizes glenohumeral joint & may predispose to further dislocation;

- combination of AP view in int rotation & Stryker Notch view allow evaluation of Hill Sachs Lesions in posterolateral aspect of humeral head;
- AP View:
- this defect is visualized on AP x-ray w/ arm in internal rotation & may be missed on routine AP views;
