ACROMIOCLAVICULAR dislocation has been a difficult lesion to treat by conservative means. After reduction of a dislocation, various forms of strappings, splints, plaster spicas, and braces have been advocated. After external fixation the joint remains in partial or complete separation in many cases. This results, either early or late, in pain and limitation of motion in the shoulder or in an obvious deformity which is objectionable, particularly to women. Many operative procedures have been published, the most popular of which are internal fixation of the joint by wire or screws, coracoclavicular screw fixation, arthrodesis, and resection of the outer end of the clavicle. Each has certain disadvantages. As the clavicle rotates on its long axis with abduction of the arm, any fixation of the acromioclavicular joint will limit abduction of the shoulder. Inman and Saunders1 state that with loss of clavicular rotation, abduction is limited to approximately 120 degrees.
