Ten patients who had an internal rotation contracture and pain after an anterior repair for recurrent dislocation of the shoulder were treated by release of the subscapularis muscle. For six of the patients, radiographs demonstrated severe osteoarthrotic changes in the shoulder as well. The release was done an average of eleven years after the original procedure, which, for most patients, had been a Putti-Platt repair. After release of the subscapularis, each patient had less pain in the shoulder and an average increase of 27 degrees of external rotation. Release of the subscapularis can offer relief of pain and of functional limitations associated with the symptoms caused by an internal rotation contracture after an anterior repair of the shoulder.
10例因复发性肩关节前脱位行前路修复术后出现内旋挛缩和疼痛的患者接受了肩胛下肌松解术治疗。其中6例患者的X线片显示肩关节也有严重的骨关节炎改变。松解术平均在初次手术11年后进行，对大多数患者而言，初次手术为Putti-Platt修复术。肩胛下肌松解术后，每位患者的肩部疼痛减轻，外旋平均增加27度。肩胛下肌松解术可缓解肩部疼痛以及与肩关节前路修复术后内旋挛缩症状相关的功能受限。
