Shoulder blade

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:
