Anatomical Relations
The acromioclavicular ligament joins the upper aspect of the acromion of the scapula to the acromial (or lateral) aspect of the clavicle. Inferiorly, the ligament is thin. It provides an attachment for the articular disc of the acromioclavicular joint.
Structure
The acromioclavicular ligament is a dense fibrous band. Its fibers are intermingled with that of the aponeuroses of the trapezius and deltoid muscles.
Function
The acromioclavicular ligament ensures stability of the acromioclavicular joint, maintaining close apposition of the acromion of the scapula with the clavicle. It also reinforces the fibrous capsule that surrounds the acromioclavicular joint.
