Complete dislocation of the acromioclavicular joint should be treated surgically. We have used the modified Weaver's procedure to reduce dislocation of the acromioclavicular joint since 1992. In this procedure, the acromioclavicular joint is reduced and fixed by two Kirshner wires and then the coracoacromial ligament is transferred to the clavicle.We operated on 13 cases of complete dislocation of the acromioclavicular joint using this procedure. The time of follow up ranged from 5 months to 43 months with an average of 22.6 months. Cases were 12 males and 1 female, and ages ranged from 25 to 66 years with a mean of 47.2 years. Eight cases were on the right side and five on the left.Postoperative results were evaluated according to Kawabe's scores. Eight cases were excellent, one was good, one was fair and three were poor. The fair and poor results were caused by persistence of pain and easy fatiguability.
