关节镜下肩峰成形术治疗肩峰下撞击综合征

目的探讨关节镜下肩峰成形术治疗肩峰下撞击综合征的方法和效果。方法分析应用关节镜行肩峰成形术治疗68例经保守治疗无效的2期肩峰下撞击综合征的情况。随访12个月以上纳入分析。采用洛杉矶加洲大学（UCLA）肩关节功能标准评价疗效。结果平均随访16．4个月，术后3-24个月有持续的症状和功能的改善，UCLA评分从术前18．3分改善到31．7分，优良率为89．7％。结论关节镜能明确诊断，镜下肩峰成形术治疗肩峰下撞击综合征能达到减压要求，效果良好。早期、持久地术后锻炼是康复的保证。

Arthroscopic acromioplasty for subacromial impingement syndrome

[Objective] To investigate the surgical technique of arthroscopic acromioplasty and its efficacy. [Methods] A retrospective analysis was done in 68 consecutive patients with grade 2 subacromial impingement syndrome who had not responded to conservative management and underwent arthroscopic acromioplasty. The mean age of patients was 61 years, with a minimum follow-up of 12 months. The assessment was performed with the shoulder-rating scale of the University of California at Los Angeles pre- and postoperatively. This 35-point scale combines scores for pain, function, the range of active forward elevation, the strength in forward elevation, and patient satisfaction. [Results] Average follow-up was 16.4 months (range, 12 to 24 months). From three months until two years postoperatively, patients showed a further progressing improvement and relief of symptoms. The average score improved from 18.3 preoperatively to 31.7 postoperatively according to UCLA shoulder score. Overall, 89.7% of patients had a good or excellent result. [Conclusion] Arthroscopy can increase the accuracy of the diagnosis. Arthroscopic decompression and acromioplasty is an effective technique for treatment of subacromial impingement syndrome. Early and persistently postoperative exercises are the key for successful rehabilitation.
