Shoulder Joint

The Scapula

The scapula (shoulder blade) forms part of the shoulder, at the back. It is a triangular, flattened bone, with several projections. The scapula is attached to the outer end of the collar bone (clavicle) at the acromioclavicular jooint. Its outer end provides a socket for the head of the upper arm bone (humerus), forming the bony articulation of the shoulder joint. The Scapula is held in place by strong muscles, which can move it in relation to the chest wall. It provides attachment for many of the muscles of the shoulder and upper arm, including the biceps.

Shoulder Seperation

A shoulder separation is the partial or complete separation of two parts of the shoulder: the collarbone (clavicle) and the end of the shoulder blade (acromion).

Shoulder

The collarbone and the shoulder blade (scapula) are connected by the acromioclavicular (AC) joint, which is held together primarily by the acromioclavicular (AC) and the coracoclavicular (CC) ligaments. In a shoulder separation (also called an acromioclavicular joint injury), these ligaments are partially or completely torn. A shoulder separation is classified according to how severely these ligaments are injured:

Glenohumeral Instability

What is Glenohumeral Instability?
After being treated for an initial dislocation of your shoulder, you may find that it feels like it's about to dislocate periodically. This feeling of giving-way is called glenohumeral instability or subluxation.

Glenohumeral instability refers to a condition in which the humeral head in the shoulder repeatedly slips out of the joint, or seems to nearly slip out.

The shoulder blade and humerus, or upper arm, form the glenohumeral joint. This is what you would normally think of as your 'shoulder joint'. The glenohumeral joint is a ball-and-socket joint, consisting of the head of the humerus, or upper arm, and the glenoid fossa, which is formed by a slightly hollowed portion of the end of the shoulder blade. The head of the humerus maintains very little contact with the glenoid itself during movement, however. Instead, the shoulder relies on a group of ligaments, muscles and tendons to help keep the humerus in the proper place, and to provide stability to the joint.
