【摘要】 目的:探讨对于重度肘管综合征(McGowen分级3级，Dellon分级3级)患者行尺神经松解前置的同时利用拇长展肌与掌长肌腱重建示指外展功能的疗效。方法:回顾性分析近5年来20例重度肘管综合征患者，行尺神经松解前置的同时利用拇长展肌与掌长肌腱重建示指外展功能的疗效，随访至术后6个月以上。根据其示指外展及拇示指夹捏肌力，计算此术式优良率。结果:患者功能恢复优14例，良6例，可0例，差0例，优良率为100%。结论:重度肘管综合征患者治疗中，行尺神经松解前置的同时利用拇长展肌与掌长肌腱重建示指外展功能，恢复拇示指的夹捏功能效果较为理想，副损伤小，安全性可靠，功能恢复优良。更多还原

【Abstract】 Objective:To investigate the diagnosis of severe cubital tunnel syndrome and the efficacy of reconstructing index finger abduction function with the abductor pollicis longus muscle and palmar longus tendon(McGowen grade 3, Dellon grade 3). Methods:A retrospective analysis of 20 patients with severe cubital tunnel syndrome in the past 5 years were carried out, and all patients were treated by ulnar nerve release and reconstruction of index finger abduction function with abductor pollicis longus muscle and palmaris longus tendon. Follow-up to more than 6 months after surgery. According to the postoperative results, the excellent and good rates were calculated. Results:Among the patients, 14 cases were excellent, 6 cases were good, 0 case was fair and poor. The excellent and good rate was 100%. Conclusion: In the treatment of patients with severe cubital tunnel syndrome, anterior ulnar nerve release is performed while using the abductor pollicis longus muscle and palmar longus tendon to reconstruct the abduction function of the index finger and restore the pinching function of the index finger, and the efficacy is relatively satisfactory. The damage is small and the function recovery is good.更多还原
