To analyze the effect of inversion trauma on peroneal nerve function, motor conduction velocity was measured in 22 patients. In the injured leg, 4-8 d post trauma motor nerve conduction velocity in the knee-caput fibulae segment of the superficial peroneal nerve was significantly smaller when compared with the contralateral leg and the control group. Five weeks post trauma these values were normal again. For three segments of the deep peroneal nerve, the motor conduction velocity was significantly reduced, 4-8 d post trauma, when compared with the control group. In the caput-ankle and knee-ankle segment, motor conduction velocity was still significantly lowered 5 wk post trauma. Lowered amplitudes of the Compound Motor Action Potentials of the extensor digitorum brevis muscle were found 4-8 d post trauma. No correlation was found between motor nerve conduction velocities and subjective clinical tests (anterior drawer sign and (manually performed) talar tilt test). The results of this study support the hypothesis that inversion trauma is frequently accompanied by lesions of the peroneal nerve. Motor conduction velocity measurements can be a valuable tool in assessing more objectively functional instability of the ankle joint induced by inversion trauma.
为分析内翻创伤对腓总神经功能的影响，对22例患者进行了运动传导速度测量。在受伤侧下肢，创伤后4 - 8天，腓浅神经膝-腓骨小头段的运动神经传导速度与对侧下肢及对照组相比显著降低。创伤后5周这些值恢复正常。对于腓深神经的三个节段，创伤后4 - 8天，与对照组相比运动传导速度显著降低。在腓骨小头-踝关节和膝关节-踝关节节段，创伤后5周运动传导速度仍显著降低。创伤后4 - 8天发现趾短伸肌复合运动动作电位的波幅降低。运动神经传导速度与主观临床检查（前抽屉试验和（手动进行的）距骨倾斜试验）之间未发现相关性。本研究结果支持以下假设：内翻创伤常伴有腓总神经损伤。运动传导速度测量可为更客观地评估内翻创伤所致踝关节功能不稳提供有价值的工具。
