Abstract
The subacromial space is the space delimited above by the coraco-acromial arc (anterior-inferior margin of the acromion, coracoacromial ligament, apex and distal third of the posterior surface of the coracoid) and below by the humeral head, by the tendons of the rotator cuff and of the long head of the biceps. The area between the tendons of the supraspinatus and the subscapularis is called the rotator interval. The acromion is flat in shape and extends laterally, then antero-laterally. We distinguish an upper surface, in close contact with the skin, bearing rough scores and vascular orifices; an inferior concavity, which forms the tip of the gleno humeral joint; a lateral margin, the bundles from which the deltoid muscle originates; and a medial margin where the surface of the acromioclavicular joint is.
In the last thirty years, the shape of the acromion has been the object/topic of several studies because it was considered the cause predisposing aliments such as sub acromial impingement and rotator cuff tendon tears.
