桡神经断伤与麻痹患者的肌电图分析

Analysis of EMG in patients with radial neurotmesis and radial paralysis

目的:总结桡神经断伤与麻痹的肌电图(EMG)表现,期望给临床早期诊断与手术治疗提供依据。方法:对56例桡神经断伤与48例桡神经麻痹的EMG资料进行分析:56例桡神经断伤中4例为医源性,52例为刀砍伤或车祸,均进行手术修复证实;48例桡神经麻痹均为肱骨骨折手术复位后水肿压迫所致。结果:56例桡神经断伤的EMG明显异常,手术后恢复时间长;48例桡神经麻痹的EMG仅有神经传导功能障碍,经非手术治疗效果好。

Objective：To summarize the change of electroencephalogram（EMGs） in patients with radial neurotmesis and radial paralysis , and provide clinical evidence for diagnosis and surgical treatment in the clinical early phase. Methods： The manifestation of EMGs in 56 patients with radial neurotmesis and 48 patients with radial paralysis. The radial neurotmesis were confirmed by operation in the 56 patients. Four radial neurotmesis patients were iatrogenicly damaged, and 52 patients were wounded by knife chops or traffic accident. The radial paralysis patients were damaged by the edema oppression after surgery retroposition with humerus fracture. Results： There were significant abnormal EMG manifestation in the 56 patients with radial neurotmesis , and their postoperative recovery time were significantly long. There were only dysfunctions of nerve conduction in the patients with radial paralysis. Non-operative treatment was also effective. Conclusions： The EMG examination may provide reliable evidence for clinical diagnosis on the early stage and surgical treatment.
