Examination reveals a palpable dent in the shoulder caused by the empty glenoid fossa , while the head of the humerus may be palpable inferior to the glenoid fossa. X-rays of the shoulder in two views are necessary to rule out fractures and confirm the diagnosis.

Reduction is followed by immobilization and subsequent physiotherapy.
