Shoulder Instability, Dislocation, and Separations

Shoulder instability is a broad category of problems that includes subluxation, dislocation, and spearations. Each of these words has very different meanings and implications, and it is important to determine the specific cause of your shoulder problem.

Hill-Sachs Injury
A Hill-Sachs lesion is an injury to the humeral head of the shoulder. The Hill-Sachs defect is a compression fracture that occurs as a result of a shoulder dislocation.

Reduce a Dislocated Shoulder
People who dislocate their shoulder are in a lot of pain until the shoulder is brought back into proper position -- called a shoulder reduction. Reducing a shoulder may be necessary if the injured person cannot be brought to medical attention

Shoulder Dislocation
A shoulder dislocation is an injury that occurs when the top of the arm bone (humerus) becomes disconnected from the shoulder blade (scapula). Shoulder dislocations occur after falls or other serious injuries.

Separated Shoulder
Shoulder separations are the result of a disruption of the acromioclavicular joint. This injury can cause pain and swelling of the shoulder.

Bankart Lesion
A Bankart lesion is a type of labral tear most commonly due to dislocation of the shoulder. Bankart lesions cause problems of persistent instability.

Do I need surgery after a shoulder dislocation?
Shoulder dislocation treatment may require surgery to stabilize the shoulder joint. Sometimes the surgery for a shoulder dislocation is performed after a single dislocation, while other times the surgeon may recommend waiting to see if the shoulder dislocations become recurrent.

Sternoclavicular (SC) Joint Dislocations
The sternoclavicular joint (also called the SC joint) is the connection of the breastbone to the collarbone. An uncommon shoulder injury is called a SC dislocation. Treatment of a sternoclavicular dislocation may require surgery if important structures behind the SC joint are being compressed.

Shoulder Instability
Shoulder instability is a problem of a loose shoulder joint. When this occurs, patients may experience symptoms of an unstable joint. Shoulder instability can be caused by a previous dislocation, or it may happen when the ligaments around the joint are too loose. Patients with shoulder instability are prone to subluxation and even repeat...

Multi-Directional Instability of the Shoulder
Multi-directional shoulder instability most often occurs in young, athletic women. Pain around the joint occurs with overhead activities. Fortunately, most cases of MDI can be treated with shoulder rehab exercises.
