Shoulder instability

In all movements of a normal shoulder, the humeral head is located centrally in the scapula. If the contact between the head and the socket disappears with certain movements, this indicates instability and you get the feeling that the shoulder is 'dislocating'.

Symptoms

In a sudden dislocation where the shoulder is completely dislocated, there is usually a pronounced pain and you cannot move the shoulder. Usually, a distinct deformity of the joint can be observed. If a partial dislocation occurs, one usually feels a click with an uncomfortable sensation in the shoulder. If this occurs frequently, an overuse of the rotator cuff can occur.

Diagnosis

With a complete dislocation, the situation is usually clear. It is necessary to make sure that no injury to the nerves or blood vessels of the arm has occurred. An X-ray is needed to confirm the diagnosis. An arthro-CT scan is usually additionally required.

Treatment

A complete dislocation should be treated as soon as possible. This can be done in the emergency department or in the operating room under light anesthesia. Depending on the injury, it is determined whether immobilization of about three weeks is necessary. Usually physical therapy is necessary to regain strength and mobility.

If the instability is chronic, rehabilitation exercises focusing mainly on strengthening the muscles around the shoulder can be started.

Surgery

If the instability is caused by an injury, surgery is needed. The problem can be corrected through keyhole surgery. After surgery, you will wear a sling. Your doctor will inform you how long you should wear it.
