Many treatment options for an acromioclavicular joint dislocation have been proposed in the literature, and which have both merits and demerits, we did a retrospective review of 16 patients who had undergone treatment by coracoacromial ligamentoplasty for an acromioclavicular joint dislocation.
The sixteen patients were operated on for acromioclavicular dislocation. The average age was 41.9years(range 19 to 55 years). Thirteen were men, and 3 were women. Seven of the 16 patients were injured in a traffic accident. Six were injured doing sports. Five patients were first seen more than 4weeks after their injury. All the cases but one were considered to be type IV dislocathion according to Rockwood's classification. The remaining case was type V. The operative technique was derived from the Cadenat and involved using a screw to fix the bone tip attached with the coracoacromial ligament to the clavicular end.
X-rays during the postoperative period showed residual separation of the acromioclavicular joint in only three cases. But none had any obvious recurrence. Fourteen patients(87.5%)were satisfied with their results. According to Kawabe's scoring system, the results were similar in both acute and chronic cases of acromioclavicular dislocations.
Ligamentoplasty employing the coracoacromial ligament gave good operative results in types IV and V acromioclavicular dislocations. The acromioclavicular ligament is ideally suited to perform ligamentoplasty for an acromioclavicular joint dislocation.
