Forty-one patients with cerebral palsy and pronation contracture of the forearm were treated with pronator teres rerouting compared with 16 patients who were treated with pronator teres tenotomy. The mean age of patients with pronator tenotomy was 4 years 3 months compared with 7 years 3 months for patients with rerouting. Follow-up averaged 94 months for tenotomy and 21 months for rerouting. Average gain in supination was 78 degrees for rerouting and 54 degrees for tenotomy. No patient lost active range of motion during follow-up. Although pronator teres tenotomy increased active supination of the forearm, greater active supination of the forearm was afforded patients treated with pronator teres rerouting.
41例患有脑瘫和前臂旋前挛缩的患者接受了旋前圆肌改道手术，与之相比，16例患者接受了旋前圆肌切断术。接受旋前圆肌切断术患者的平均年龄为4岁3个月，而接受改道手术患者的平均年龄为7岁3个月。切断术的随访平均为94个月，改道手术的随访平均为21个月。改道手术的旋后平均增加78度，切断术的旋后平均增加54度。随访期间没有患者失去主动活动范围。虽然旋前圆肌切断术增加了前臂的主动旋后，但接受旋前圆肌改道手术的患者前臂的主动旋后增加得更多。
