The topography of the superficial peroneal nerve (SPN) and its terminal branches were studied, with the aim of providing further anatomical details for leg and foot in the Turkish newborn fetuses.
Limbs from twenty newborn cadavers were dissected. The course of the SPN on the leg and its terminal branches on the foot were investigated.
The SPN was lateral (75%), anterior (15%), or branched in both areas (10%) of the cases. The SPN in the dorsum of the feet branched further into medial dorsal cutaneous nerve (MDCn) and intermediate dorsal cutaneous nerve (IDCn). In 82.5% of the cases the MDCn and the IDCn split into three and two branches, respectively. In 10% of the cases, the MDCn gave off three, and the IDCn one terminal branches. In 7.5% of the cases, the MDCn had three while the IDCn had two branches that communicated with the lateral dorsal cutaneous nerve.
The course of SPN on the anterolateral surface of the leg and its terminal branches on the dorsal surface of the foot were quite different. This unusual variant location will enable the surgeon to find and preserve the SPN and its terminal branches.
研究腓浅神经（SPN）的局部解剖及其终末分支，旨在为土耳其新生儿胎儿的腿部和足部提供更多解剖学细节。
解剖20具新生儿尸体的四肢。研究SPN在腿部的走行及其在足部的终末分支。
在75%的病例中，SPN位于外侧，15%位于前方，10%在两个区域均有分支。足部背侧的SPN进一步分支为内侧足背皮神经（MDCn）和中间足背皮神经（IDCn）。在82.5%的病例中，MDCn和IDCn分别分为3支和2支。在10%的病例中，MDCn发出3支终末分支，IDCn发出1支。在7.5%的病例中，MDCn有3支，IDCn有2支并与足背外侧皮神经相连。
SPN在小腿前外侧表面的走行及其在足背表面的终末分支有很大差异。这种不寻常的变异位置将有助于外科医生找到并保留SPN及其终末分支。
