Shoulder subluxation, a partial dislocation, occurs when the humerus bone partially slips out of the shoulder socket. Understanding the causes and treatments, such as braces and exercises, can help manage pain and prevent further injury.
The shoulder joint connects the round head of the humerus bone with the socket-shaped glenoid fossa.
Like a golf ball on a tee, only a small part of the humeral head touches the glenoid fossa, making the highly mobile shoulder joint prone to instability.
