肩関節脱臼に対するWeaver変法の経験

抄録

Complete dislocation of the acromioclavicular joint usually accompanies tears of the acromioclavicular and coracoclavicular ligments. This injury should be treated sargically. We have used modified Weaver's procedure to reduct dislocation of the acromioclavicular joint since 1982.
15cases were followed postoperatively. Time of follow-up ranged from four months to 37 months with an average of 16 months. All of cases were divided into two groups by two different procedures. One is the case with which were fixed the acromioclavicular joint by two Kirschner's wires, and added transfer of the coracoacromial ligament to the clavicular (modified Weaver's procedure ( I )). Another is the cases with which were fixed the clavicula to the spina of the scapula by Kirschner's and added bony suture of the coracoacromial ligament to the clavicula (modified Weaver's procedure (II)). Eight males and two females were trested by modified Weaver's procedure (II), and five by modified Weaver's procedure (II ). Postoperative results were evaluated by means of Kawabe's. scores. Of ten, which were treated by modified Weaver's procedure ( I ), nine were excellent, and one fair. On the other hand, of five, which were treated by modified Weaver's procedure (II), four were excellent, and one good.
Roentgenologically, the acromioclavicular joint was completely reducted in eight, and subluxated in seven.
The results between two groups were almost clinically and roentgenologically same. However, we should recomend modified Weaver's procedure (II) for dislocation of the acromioclavicular joint. On comparison with these two procedure, we believe that modified Weaver's procedure (II). will not destroy the acromioclavicular joint, further and be sure to keep the joint reducted after operation.
