Abstract

The acromioclavicular joint is commonly affected by traumatic and degenerative conditions. Most injuries are due to direct trauma, such as a fall on the shoulder. Although there is general agreement on treatment of type I, Ⅱ, Ⅳ, V and VI acromioclavicular injuries, the treatment of type Ⅲ injuries remains controversial. Sixty patients, ranging in age from 19 to 57 years(average, 32), were evaluated an average of 57.5 (range, 13 to 96) months after surgical reconstruction for Rockwood type Ⅲ Ⅳ, V acromioclavicular dislocation. Phemister method (47 cases), Bosworth (3 cases), Weaver and Dunn method (10 cases) were used to correct displacement. An increase of the coracoclavicular distance of the injured shoulder over the normal shoulder was average 7.1㎜ at initial, average l㎜ on postoperatively, and average 2㎜ at follow-up. Overall, 54 of 60(90%) patients achieved satisfactory results. Degree of increase of the coracoclavicular distance has no inliluence to clinical results.
