腓浅神经的解剖学观察及临床意义

Anatomical observation and clinical significance of peroneus superficialis nervus

目的 为探讨腓浅神经卡压征的发病机制。方法 观察 2 8侧成人下肢腓浅神经的行程、穿出深筋膜的部位、在浅筋膜内的分支情况 ;测量腓浅神经筋膜下段的长度 ,出口处的筋膜厚度 ,出口大小 ,腓浅神经的直径。结果 腓浅神经在小腿中下 1 / 3处穿出深筋膜 ,筋膜下段长为男 (4 8 0 8± 0 1 4 )mm、女 (4 0 0 1± 0 1 2 )mm ;镰状切迹筋膜的厚度为男 (0 4 8± 0 0 4 )mm、女 (0 4 3± 0 0 9)mm ,出口的直径为男 (4 1 8± 0 0 7)mm、女 (4 1 5± 0 1 1 )mm。结论 腓浅神经穿出部位深筋膜增厚 ,出口小 ,是产生腓浅神经卡压的主要原因 ,手术治疗时 ,可在腓浅神经出口处纵行切开深筋膜 ,将该神经向上游离 4 5mm 。

Objective To provide basic information of preoneus superficialis nervus symptom complex.Method Observed the ran length of peroneus superficialis nervus.Cut across the place of the deep aponeurosis of the peroneus superficialis nervus.Results The peroneus cut across the deep aponeurosis at the middle low place the length of the lower segment of peroneus was(48 08±0 14)mm in male,and (40 01±0 12)mm in female.The thiclcness of aponerosis at the outlet place was (0 48±0 04)mm and (0 43±0 09)mm in male and female respectively.The diameter at the outlet place was (4 18±0 07)mm in male and (4 15±0 11)mm in female.Conclusion At the outlet place of peroneus superficialis nervus the deep aponeurosis becomes thioker and the outlet is smaller.This is the main reason that produce the peroneus superficialis nervus.In arder to achierc the goal of anatomy.We can cut deep apoueurosis and make if free up to 45 mm.When caning out the operation.
