Shoulder Instability, Subluxations and Dislocations

Multi-directional Instability (MDI)/Anterior Glenohumeral Joint Instability

Shoulder pain

Shoulder instability occurs when the head of the upper arm bone is forced out of the shoulder socket. This can happen as a result of a sudden injury or from overuse. A dislocation may occur anteriorly (front), posteriorly (back) or inferiorly (down).


Dislocations may occur repeatedly once the ligaments, tendons, and muscles around the shoulder become loose or torn. Repeated episodes of subluxations (partial dislocation) or dislocations lead to an increased risk of developing arthritis in the joint.


There are several non-surgical and surgical options to treat shoulder instability.
