This is an intra-articular 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).
Further details on clinical and radiological examination can be found here .
These fractures are further subdivided into two categories:
These fractures are simple anterior, partial articular fractures of the glenoid rim or fossa.
These fractures are multifragmentary anterior, partial articular fractures of the glenoid rim or fossa.
