Glenoid fossa, partial articular, anterior simple

These fractures are simple anterior, partial articular fractures of the glenoid rim or fossa.

This is an intraarticular fracture of the anterior glenoid rim or fossa. Most of these fractures are associated with anterior dislocation of the shoulder. The anterior movement of the humeral head will typically cause a shearing lesion of the anterior glenoid rim. The anterior inferior fractures are associated with shoulder instability (Bony Bankart lesion).
