    Abstract:
    OBJECTIVE: To evaluate the early result of triple Endobutton technique for reconstructing coracoclavicular ligament of chronic complete acromioclavicular joint dislocations. METHODS: Between January 2009 and June 2010, 14 patients with chronic complete acromioclavicular joint dislocations were treated with triple Endobutton technique for reconstructing coracoclavicular ligament. There were 10 males and 4 females with a mean age of 38.5 years (range, 26-52 years). Injury was caused by traffic accident in 7 cases, by falling in 5 cases, and by bruise in 2 cases. The average time was 47 days from injury to the operation (range, 29-75 days). All patients had pain and activity restriction. The X-ray films showed complete dislocation of acromioclavicular joint. According to Allman's type, all cases were classified as III degree complete dislocations. RESULTS: At postoperation, wound healed by first intention with no early complication of infection or neurovascular injury. All patients were followed up 18.3 months on average (range, 13-30 months). Acromioclavicular joint subluxation occurred in 1 patient at 1 week after operation, and no redislocation or other complication occurred in the other patients. American Shoulder and Elbow Surgeons (ASES) score was 90.8 +/- 4.1 at last follow-up, showing significant difference when compared with the preoperative score (65.3 +/- 4.4) (t = -17.57, P = 0.00); Constant-Murley score was 91.7 +/- 3.9, showing significant difference when compared with preoperative one (71.5 +/- 4.6) (t = -75.02, P = 0.00). The definite answer in Simple Shoulder Test (SST) averaged 9.7 (range, 7-12). CONCLUSION: The triple Endobutton technique for reconstructing coracoclavicular ligament is an effective method in treatment of chronic complete acromioclavicular joint dislocations. The short-term results are satisfactory.
