Shoulder instability is one of the most common and debilitating symptom of a shoulder injury.  It is a condition that occurs when the muscles, tendons, bones and ligaments that surround the shoulder do not work together to secure the ball within the socket. Instability of the posterior (back) side of the shoulder joint includes sensations of dislocations and sub-luxations (pseudo dislocations) of the shoulder joint to posterior. This can cause pain and symptoms of instability.

Arthroscopic (key-hole surgery) treatment of the unstable shoulder has evolved significantly in recent years creating good results. The general surgical principles are to restore the ligaments and cartilage rim to its anatomic attachment and to reestablish the appropriate tension in the ligament complex and joints and capsule.

The surgical technique of the arthroscopic posterior shoulder stabilizationis further explained in this short video.
