Abstract
Dislocation of the acromioclavicular joint, which is a relatively frequent trauma, has not yet been treated with an unified method.
Based upon the opinions of anatomical repair of the dislocation, we successfully reduced 20 cases with primary repair of the coracoclavicular ligament. The subjects were 20 cases of Tossy's classification grade III (15 males, 5 females), aged 17-70 years (averaging 33.1).
Mean follow-up time after the operation was 5.5 months (3-13 months). All cases received both primamy repair of the coracoclavicular ligment and acromioclavicular internal fixation with K-wires, and some cases viewed resection of injured acromiclavicular disc and repair of iojured softtissues such as the trapezius and deltoid muscle.
K-wires were extracted 4 weeks after operation in principle. Pain, Range of motion of shoulder joint, X-ray findings, and other clinical signs were examined postoperatively. Restricted R. O. M., pain, subluxation and calcification were noted in 4 cases, and only 1 case showed disturbed A. D. L., Our results were practically satisfactory, suggesting the serviceableness of the present treatment for the dislocation.
