An apparatus for surgically reducing and internally fixing a shoulder acromioclavicular joint dislocation. The apparatus preferably comprises a button and a washer, the washer being flexibly secured to the coracoid process of the scapula by means of a bone screw, the button and washer being secured together by means of a first suture. A second suture is provided and secured between the button and a needle, such that the needle and associated button, may be advanced through a hole drilled through the clavicle. The button and the washer may then be tightened, reducing the coracoclavicular distance, by means of the first suture connected therebetween, to reduce and hold a desired acromioclavicular joint dislocation.
