Twenty-five consecutive adult patients (32 shoulders) with deltoid contracture were treated with distal release and followed up for an average of 4 years (range, 2-8 years). All shoulders achieved full range of motion and complete relief of pain and deformity after 3 months. No muscle weakness was clinically evident. In addition, another five adult patients (nine shoulders) with deltoid contracture were treated with distal release and quantitative measurement of muscle power recovery around the shoulder with Cybex 340 dynamometer before surgery, and 3 months and 1 year after surgery. Isokinetic peak torque of shoulder muscles did not decrease significantly at either 60 degrees per second or 180 degrees per second angular velocity after surgery. In addition, the shoulder extensors showed a twofold increase of isokinetic peak torque after surgical release of deltoid contracture. Distal release was a simple and effective surgical technique to treat deltoid contracture in adults. All patients in this series achieved a satisfactory outcome.
连续25例患有三角肌挛缩的成年患者（32个肩部）接受了远端松解术治疗，并平均随访4年（范围2 - 8年）。所有肩部在3个月后均达到了全关节活动范围，疼痛和畸形完全缓解。临床上未发现肌肉无力。此外，另外5例患有三角肌挛缩的成年患者（9个肩部）接受了远端松解术，并在手术前、术后3个月和1年使用Cybex 340测力计对肩部周围肌肉力量恢复情况进行了定量测量。术后在60度/秒或180度/秒角速度下，肩部肌肉的等速峰值扭矩均未显著降低。此外，三角肌挛缩手术松解后，肩部伸肌的等速峰值扭矩增加了两倍。远端松解术是治疗成人三角肌挛缩的一种简单有效的手术技术。本系列所有患者均取得了满意的结果。
