肘管综合征的成因和神经学检查

Etiology and Neurological Examination of the Cubital Tunnel Syndrome

肘管综合征是常见的周围神经嵌压症之一。我院1990年12月—1995年12月共收治该症22例,均经严格的神经学检查和病因学分析后确诊,治疗全部行尺神经前移术。术后随访20例,平均随访2年5月,12例恢复正常,6例明显好转,2例较差。作者认为,当手部感觉改变和运动障碍为单纯尺神经损伤引起,肌电图提示尺神经传导速度在肘管部减慢,肘管内或外可找到神经受损原因,肘管综合征即可确诊;当肌电提示尺神经传导在肘管部减慢,而肘管内或外找不到神经受损原因,应高度疑诊肘管综合征。

The cubital tunnel syndrome is one of the common compression peripheral neuropathy. 22 patients with this syndrome were all diagnosed by strict neurological examination and etiological analyses, and all treated by anterior transposition of the ulnar nerve in our hospital from Dec. 1990 to Dec. 1995. 20 cases were followed-up for 29 months in average. 12 cases of them had excellent results,6 cases good and 2 cases poor. The authors believed that the cubital tunnel syndrome was diagnosed when the loss of the motor and sensory in the hand were only attributed to ulnar injure,the electromyography indicated a slowed conduction of the ulnar nerve at the cubital tunnel and the factors causing the nerve injury were found in elbow; the syndrome was highly suspected when the electromyography indicated a slowed conduction of the ulnar nerve at the cubital tunnel but none of the factors causing the syndrome was found before operation.
