We report the electrophysiological study of a patient with carpal tunnel syndrome who, besides the features of median nerve entrapment at the wrist, showed an aberrant motor innervation of Martin-Gruber type and an unusual distribution of the sensory innervation of the fingers. Studies based on collision between sensory volleys showed that the fibers supplying the anomalous innervation did not follow the same path as the aberrant motor fibers. This finding is consistent with the hypothesis that Martin-Gruber anastomosis is made up of motor axons only, and supports the idea that other abnormalities of innervation may be found in patients with Martin-Gruber anastomosis.
我们报告了一名腕管综合征患者的电生理研究结果。该患者除了具有腕部正中神经卡压的特征外，还表现出Martin-Gruber型异常运动神经支配以及手指感觉神经支配的异常分布。基于感觉冲动碰撞的研究表明，提供异常神经支配的纤维与异常运动纤维的走行不同。这一发现与Martin-Gruber吻合仅由运动轴突组成的假说一致，并支持了在Martin-Gruber吻合患者中可能发现其他神经支配异常的观点。
