The acromioclavicular joint (AC JOINT) serves as a linkage between the appendicular and axial skeleton. Injury to the acromioclavicular (AC) joint accounts for nearly half of all sports-related shoulder injuries. Dislocation of the acromio-clavicular joint commonly occurs in young adults following a fall with direct impact onto the shoulder. This produces a sprain followed by rupture of the acromio-clavicular ligaments with loss of horizontal stability. With increasing force, rupture of the coraco-clavicular ligaments with displacement of the lateral clavicle occurs with loss of vertical stability, producing a complete dislocation. Numerous surgical methods are used to treat acromioclavicular joint dislocations include the transfer of the coracoacromial ligament to the outer clavicle as popularized by Weaver and Dunn, Coracoclacicular screw fixation, intraarticular acromioclavicular fixation using pins or K-wires and anatomical acromioclavicular joint reconstruction.
