The acromioclavicular joint, frequently referred to as the AC joint, is an essential anatomical structure situated on the top of the shoulder where the lateral end of the clavicle (collarbone) articulates with the acromion process of the scapula. This joint is critical to the stability and operation of the shoulder complex, allowing for a wide range of motion while preserving the structural integrity of the shoulder girdle.
