This is a transverse or oblique intra articular fracture (not rim).
There are many potential variations of the fracture line.
Some of these fractures are associated with inferior dislocation of the shoulder. Due to the fracture mechanism, there will often be an impaction of the inferior glenoid segment.
Further details on clinical and radiological examination can be found here .
These fractures are further subdivided into two categories:
These are simple transverse or oblique fractures of the glenoid fossa (not rim).
These are multifragmentary transverse or oblique fractures of the glenoid fossa (not rim).
