To identify the optimal distal stimulation point for conventional deep peroneal motor nerve (DPN) conduction studies by a cadaveric dissection study.
DPN was examined in 30 ankles from 20 cadavers. The distance from the DPN to the tibialis anterior (TA) tendon was estimated at a point 8 cm proximal to the extensor digitorum brevis (EDB) muscle. Relationships between the DPN and tendons including TA, extensor hallucis longus (EHL), and extensor digitorum longus (EDL) tendons were established.
The median distance from the DPN to the TA tendon in all 30 cadaver ankles was 10 mm (range, 1-21 mm) at a point 8 cm proximal to the EDB muscle. The DPN was situated between EHL and EDL tendons in 18 cases (60%), between TA and EHL tendons in nine cases (30%), and lateral to the EDL tendon in three cases (10%).
The optimal distal stimulation point for the DPN conduction study was approximately 1 cm lateral to the TA tendon at the level of 8 cm proximal to the active electrode. The distal stimulation site for the DPN should be reconsidered in cases with a weaker distal response but without an accessory peroneal nerve.
通过尸体解剖研究确定传统腓深神经运动神经（DPN）传导研究的最佳远端刺激点。
对20具尸体的30个踝关节进行DPN检查。在距短伸肌（EDB）近端8 cm处估计DPN到胫骨前肌（TA）肌腱的距离。建立DPN与包括TA、拇长伸肌（EHL）和趾长伸肌（EDL）肌腱在内的肌腱之间的关系。
在所有30个尸体踝关节中，距EDB近端8 cm处DPN到TA肌腱的中位距离为10 mm（范围1 - 21 mm）。DPN位于EHL和EDL肌腱之间18例（60%），位于TA和EHL肌腱之间9例（30%），位于EDL肌腱外侧3例（10%）。
DPN传导研究的最佳远端刺激点位于活动电极近端8 cm水平处TA肌腱外侧约1 cm处。对于远端反应较弱但无副腓神经的病例，应重新考虑DPN的远端刺激部位。
