腱板断裂に対する当院の治療成績

抄録

We studied the postoperative poor results of rotator cuff ruptures.
Operations were performed on 25 patients (25 shoulders). The age of 21 men and 4 women ranged from 26 to 77 years (mean: 57.9 years). The postoperative follow-up period averaged 32.6months (range 6-77 months). There were one small tear,11 medium,5 large and 7 massive tears. The operative procedures were 15 McLaughlin methods,3 Takagishi,4 side to side and 3 end to end sutures. At follow-up, the people who had under 15 points of pain in the JOA score or could not elevate their arm over 90° were estimated as poor.
At follow-up, we had 6 poor results which included 4 cases of massive tears. Two cases had reoperations because of postoperative abduction contracture and rerupture of the repaired rotator cuff. One was a rotator cuff release operation, and the other was a latissimus dorsi transfer. In the two poor results of medium tears, their causes were a fatty degeneration of the supraspinatus and a preoperative osteoarthritic change of the humeral head.
Besides the afore-mentioned cases, we must report on two cases of glenohumeral osteoarthritic changes after rotator cuff sutures. One case was a 26-year-old man and the other was a 35-year-old woman. They had medium tears of the supraspinatus tendons on which we performed McLaughlin method or end to end suture. They had an abduction contracture of their shoulders for about 3 to 6 months after the operations. The cause of their osteoarthritic changes might be a postoperative abduction contracture.
