It is most common in young athletes injured while playing rugby, football, basketvall, or volleyball. This injury has also been reported while participating in activities such as diving, surfing, and skiing.

The glenohumeral ligaments are a group of four ligaments and two separate bands of tissue. Together, they hold the head of the humerus in the acetabulum, which shoulder is the shoulder socket.

Without these ligaments in place, the shoulder is unstable. It may repeatedly dislocate causing pain and discomfort. Depending on how much damage has been done, conservative care may be all that's needed. More often, surgery is done to repair the damage and stabilize the shoulder.

With the proper treatment and follow-up rehab, many athletes are able to return to their sport. The key is accurate diagnosis and treatment to repair all parts that have been damaged.
