Acromioplasty is an arthroscopic surgical procedure involving the acromion, a bony process of the shoulder blade.. Generally, it implies removal of a small piece of the surface of the acromion that is in contact with a tendon of the rotator cuff causing, by friction, damage to the tendon.
Subacromial impingement is not free of criticism. First, the identification of acromion type shows poor intra- and inter-observer reliability. [26] [27] Second, a computerized three-dimensional study failed to support impingement by any portion of the acromion on the rotator cuff tendons in different shoulder positions. [28]
A separated shoulder, also known as acromioclavicular joint injury, is a common injury to the acromioclavicular joint. [2] The AC joint is located at the outer end of the clavicle where it attaches to the acromion of the scapula. [2] Symptoms include non-radiating pain which may make it difficult to move the shoulder.
The acromion is a bony process at the end of the scapula. The shoulder is a complex mechanism involving bones, ligaments, joints, muscles, and tendons. The two main causes are acute injury or chronic and cumulative degeneration of the shoulder joint. Mechanisms can be extrinsic, intrinsic or a combination of both. [27]
Subacromial bursitis is a condition caused by inflammation of the bursa that separates the superior surface of the supraspinatus tendon (one of the four tendons of the rotator cuff) from the overlying coraco-acromial ligament, acromion, and coracoid (the acromial arch) and from the deep surface of the deltoid muscle.

It is attached, by its apex, to the summit of the acromion just in front of the articular surface for the clavicle; and by its broad base to the whole length of the lateral border of the coracoid process. [2] This ligament, together with the coracoid process and the acromion, forms a vault for the protection of the head of the humerus.
