About Shoulder Instability
Shoulder instability occurs when the structures that surround the shoulder joint do not work to maintain the ball in its socket. If the joint is too loose, it may slide out of place causing shoulder subluxation, or if it comes out of place completely, it causes shoulder dislocation.
Causes of Shoulder Instability
Patients who have had previous shoulder dislocations can develop chronic shoulder instability. When shoulders are dislocated, the ligaments supporting the shoulder are torn and can heal too loosely thereby making the shoulder prone to repeated dislocations and instability.

Diagnosis of Shoulder Instability
A thorough physical exam is important to diagnose chronic shoulder instability. X-rays may be necessary to show if the shoulder bones are in the proper place and an MRI may be needed for further detail of the structures of the shoulder.
Treatment for Shoulder Instability
Non-surgical Treatment
Proper physical therapy with shoulder strengthening exercises is important to help maintain the shoulder in proper position. Cortisone injections may also be helpful to reduce inflammation and help with shoulder stiffness.
Surgical Treatment
The surgical treatment of chronic shoulder instability can include a Bankart repair. For more information, click here.
