There are several documented variations of the sural nerve noted within the literature. This cadaveric study was conducted to provide a surgical perspective to either directly addressing the sural nerve, or avoiding it depending on the injury or pathology being surgically addressed.
Twenty-five preserved cadaveric limbs were dissected from the popliteal fossa to the foot. Three locations of the course of the sural nerve data were analyzed. The first location (M1) was from the head of the fibula to the sural nerve. The second location (M3) was from 2.54 cm proximal to the distal tip of the lateral malleolus to the sural nerve. The third location (M2) was from the shaft of the fibula at the halfway point between measurements 1 and 2 to the course of the sural nerve. The types of variations were noted as well, compared to previous studies, highlighting the abundance of sural nerve variations in the lower limb that clinicians and surgeons need to be aware of and ready to address.
The sural nerve courses 4.6 cm posterior from the fibula at the proximal fibula and mid fibula and 4.5 cm at the distal fibula. The 25 sural nerve variations are not reflective of what has been previously published in the literature.
The data can be utilized in preoperative planning in addressing or avoiding the sural nerve involving the posterior superficial compartment of the leg.
文献中记载了腓肠神经的几种变异情况。本尸体研究旨在从手术角度出发，根据所处理的损伤或病理情况，直接处理腓肠神经或避免损伤该神经。
对25条保存的尸体下肢从腘窝至足部进行解剖。分析了腓肠神经走行的三个位置的数据。第一个位置（M1）是从腓骨头至腓肠神经。第二个位置（M3）是从外踝远端尖端近端2.54厘米处至腓肠神经。第三个位置（M2）是从测量1和测量2中间点的腓骨干至腓肠神经走行处。还记录了变异类型，并与先前研究进行比较，突出了下肢腓肠神经变异的丰富性，临床医生和外科医生需要了解并准备应对这些变异。
腓肠神经在腓骨近端和腓骨中部从腓骨后方4.6厘米处走行，在腓骨远端从腓骨后方4.5厘米处走行。25例腓肠神经变异情况与先前文献报道不一致。
这些数据可用于术前规划，以处理或避免涉及小腿后浅筋膜室的腓肠神经问题。
