Shoulder subluxation can lead to soft tissue damage as traction damage can occur due to gravitational pull forces and poor protection is offered by a weak shoulder. Shoulder subluxation is usually quite painful, and there might be a partial numbness of the shoulder, arm and hand. [21].

An anterior dislocation involves external rotation of the shoulder; that is, the shoulder rotates away from the body. Posterior dislocations are uncommon and are often associated with specific injuries like lightning strikes, electrical injuries, and seizures.

The rotator cuff muscles and the tendons that move the shoulder provide a significant amount of protection for the shoulder joint. Dislocations of the shoulder occur when the head of the humerus is forcibly removed from its socket in the glenoid fossa.

Right: Head of the humerus dislocated to the front of the shoulder. Once the ligaments, tendons, and muscles around the shoulder become loose or torn, dislocations can occur repeatedly. Chronic shoulder instability is the persistent inability of these tissues to keep the arm centered in the shoulder socket.

1 Immobilization with a sling is important to decrease the risk of a repeat dislocation. 2  First dislocations are immobilized in an external rotation position. 3  Recurrent dislocations may be immobilized in a regular sling. 4  Early follow-up is important to decide when to begin allowing shoulder motion.

The shoulder is the most moveable joint in your body. It helps you to lift your arm, to rotate it, and to reach up over your head. It is able to turn in many directions. This greater range of motion, however, can cause instability. 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.

Glenohumeral subluxation is defined as a partial or incomplete dislocation that usually stems from changes in the mechanical integrity of the joint.

In the shoulder joint, the head of the humerus (upper arm bone) sits in the glenoid fossa, an extension of the scapula, or shoulder blade. Because the glenoid fossa (fossa = shallow depression) is so shallow, other structures within and surrounding the shoulder joint are needed to maintain its stability.

The shoulder joint is the most mobile joint in the body and allows the arm to move in many directions. This ability to move makes the joint inherently unstable and also makes the shoulder the most often dislocated joint in the body.

In a subluxation, the humeral head slips out of the glenoid cavity as a result of weakness in the rotator cuff or a blow to the shoulder area. A subluxation can occur in one of three types: anterior (forward), posterior (backward), and inferior (downward). The difference with a shoulder dislocation is the fact that the humeral head pops back into its socket.
