The shoulder (glenohumeral joint) is the most mobile joint of the human body, the counterpart is that it is unstable because the two pieces of bone do not fit together very much.
The stability then rests on the ligaments, the joint capsule and the peripheral muscles.
After trauma or first dislocation, these stabilizing elements can be damaged and not heal, which facilitates the occurrence of new dislocations.
Rehabilitation is useful to strengthen the shoulder muscles that help stabilize the shoulder joint, although in some arm position (arm in arm as when preparing to throw a ball or a stick) the risk remains important to dislocate.
