摘要
目的：介绍正中神经返支卡压征，由于国内未见报道，旨在引起同道们对该病的注意和认识。方法：本组３例，临床特征为拇指对掌功能受限，大鱼际肌萎缩，但手部感觉无障碍。均采用手术治疗。除作神经松解术外，在神经外膜下及周围软组织间注入醋酸泼尼松龙２５ｍｇ。结果：术后随访１～５个月，拇指对掌功能完全恢复。结论：正中神经返支卡压的病因与局部解剖有关，其诊断依据主要为拇指对掌、对指功能障碍，病程长时大鱼际肌可出现萎缩，但手部桡侧半无感觉障碍。
Objective: Three cases of median nerve recurrent branch entrapment syndrome are introduced for the first time domestically. The aim is to catch the attention to this disease which is characterized by impaired thumb opposition and atrophy of thenar muscles accompanied with no significant finger hypoesthesia. Methods: Comprehensive neurolysis of the median nerve recurrent branch and release of the entrapment factors are performed, followed by injection of prednisonlon 25mg in neurolemma and surrounding soft tissue. Results: The follow up study shows good recovery of the hand function. Conclusions: The recurrent branch entrapment is closely related to the local anatomy. The clinical course of the disease is fairly long while the diagnosis is definite, so only surgical treatment can remove the entrapment completely and restore the function of the branch.
