The acromioclavicular joint is an important component of the shoulder girdle; it links the axial skeleton with the upper limb.

The acromioclavicular capsule and ligaments stabilize the joint in the horizontal direction, while the coracoclavicular ligament complex provides vertical stability. Dynamic stability is afforded by the deltoid and trapezius muscles during
