肩腱板断裂に対する関節鏡視下肩峰下除圧術の治療成績(腱板不全断裂を中心に)

抄録

The purpose of this study was to evaluate the results of 29 arthroscopic subacromial decompressions (ASD) for rotator cuff tears.
ASD was carried out on tears of the rotator cuff of 29 patients. There were 15 males and 14females, with an average age of 52 years (range 15 to 86 years). Eighteen had a partial thickness tear (PTT),5 had a full thickness tear (FTT) and 6 had a massive tear (MT). Patients with PTT were classified at the time of arthroscopy using Synder's classification. Two patients had Al,2 had A2,2 had A3,5 had B1 and 7 had B2. Patients were evaluated pre and postoperatively on the JOA shoulder rating scale (JOAS).
In the PTT of 18 patients, sixteen had a major improvement on the JOAS 75.9 ± 10.4 preoperatively to 90.7 ± 6.4 postoperatively. In the PTT, Snyder's grade (severity and location) did not affect the results. In the FTT of 5 patients, four had a major improvement on the JOAS 66.8 ± 14.3 to 83.8 ± 10.8. In the MT of 6 patients, three had a relative improvement in the rating of pain but 3 had unsatisfactory results on the JOAS 58.7 ± 7.4 to 62.3 ± 7.8.
We concluded that ASD is effective in the treatment of PTT and FTT (a small tear), but cannot support it as the treatment for a massive tear of the rotator cuff.
