What is the definition or description of: dislocated shoulder?

Glenohumeral... A glenohumeral dislocation occurs when the head of humeus displaces in relationship to the glenoid fossa. Most glenohumeral dislocations occur when the humerus slips forward (anterior) on the fossa. A disocated shoulder must be reduced, & a post-reduction x-ray is necessary to check for any fractures/ ensure proper realignment. Dislocations may also cause soft tissue (rotator cuff/ labrum) damage.
