INTRODUCTION
We evaluated anatomic variations of distal branches of the superficial fibular sensory nerve electrophysiologically.
METHODS
Orthodromic nerve conduction studies (NCS) of the first and third branches (M-I, M-III) of the medial dorsal cutaneous nerve and the fourth and fifth branches (I-IV, I-V) of the intermediate dorsal cutaneous nerve (IDCN) were performed. To find anomalous innervations from the dorsal sural nerve (DSN) in the IDCN territory, NCS of the fourth and fifth branches (S-IV, S-V) of the DSN were also performed.
RESULTS
All sensory nerve action potentials (SNAPs) of M-I and M-III could be obtained bilaterally from 31 healthy Japanese volunteers. SNAPs of I-IV and I-V were recordable in 85.5% and 43.5% of feet, respectively. Anomalous innervations from the DSN were confirmed in 71.0% of S-IV and 93.5% of S-V.
CONCLUSION
These results suggest that anatomical variations in the IDCN territory are very frequent in Japanese subjects. Muscle Nerve 55: 74-76, 2017.
引言
我们通过电生理学方法评估了腓浅感觉神经远端分支的解剖变异情况。
方法
对内侧足背皮神经的第一和第三分支（M-I、M-III）以及中间足背皮神经（IDCN）的第四和第五分支（I-IV、I-V）进行顺向神经传导研究（NCS）。为了发现IDCN区域内来自腓肠背侧皮神经（DSN）的异常支配，还对DSN的第四和第五分支（S-IV、S-V）进行了NCS。
结果
31名健康日本志愿者双侧均能引出M-I和M-III的所有感觉神经动作电位（SNAPs）。I-IV和I-V的SNAPs分别在85.5%和43.5%的足部可记录到。在71.0%的S-IV和93.5%的S-V中证实存在来自DSN的异常支配。
结论
这些结果表明，IDCN区域的解剖变异在日本人群中非常常见。《肌肉与神经》55: 74 - 76, 2017年。
