PURPOSE The aim of this study is to compare the distance from the peroneal tendons sheath to the sural nerve in different points proximally and distally to the tip of the fibula. METHODS Ten fresh-frozen lower extremities were dissected to expose the nerves and tendons. Having the posterior tip of the fibula as a reference, the distance between the tendons sheath and the sural nerve was measured in each point with a tachometer with three independent different observers. Two measures were taken distally at 1.5 and 2 cm from fibula tip and 3 measures were performed proximally at 2, 3, and 5 cm from fibula tip. Data were described using means, standard deviations, medians, and minimum and maximum values. RESULTS The average distance between distance between the fibula tip and sural nerve is 16.6 ± 4.4 mm. The average distance between peroneal tendons sheath and the sural nerve at 5 cm, 3 cm, and 2 cm from the proximal fibular tip was 29.6 ± 3.2 mm, 24.2 ± 3.6 mm, and 19.7 ± 2.7 mm, respectively. The average distance between the peroneal tendons sheath and the sural nerve at 2 cm and 1.5 cm distal to fibular tip was 9.1 ± 3.5 mm and 7.8 ± 3.3 mm, respectively. CONCLUSION The distance from the peroneal tendons sheath to the sural nerve decreases from proximal to distal. As the distance between the peroneal tendons sheath and the sural nerve decreases from proximal to distal, performing the tendoscopy portal more distally would increase the risk of nerve iatrogenic injury.

从腓骨腱鞘到腓骨后尖的腓肠神经的距离从近端到远端减小。

目的本研究的目的是比较腓骨腱鞘到腓骨神经近端和远端不同点在腓肠神经的距离。方法解剖十只新鲜冷冻的下肢，露出神经和肌腱。以腓骨的后尖端为参考，用三个独立的不同观察者的转速计在每个点测量肌腱鞘和腓肠神经之间的距离。在距腓骨尖1.5和2 cm处向远侧采取两项措施，并在距腓骨尖2、3和5 cm处向近侧采取3项措施。使用均值，标准差，中位数以及最小值和最大值描述数据。结果腓骨尖端与腓肠神经之间的平均距离为16.6±4.4 mm。腓骨腱鞘与腓肠神经之间距腓骨近端5 cm，3 cm和2 cm的平均距离分别为29.6±3.2 mm，24.2±3.6 mm和19.7±2.7 mm。腓骨腱远端到腓骨尖的2 cm和1.5 cm处腓骨鞘与腓肠神经之间的平均距离分别为9.1±3.5 mm和7.8±3.3 mm。结论从腓腱鞘到腓肠神经的距离从近端到远端减小。随着腓骨腱鞘和腓肠神经之间的距离从近端到远端减小，在更远端进行肌腱镜检查门将增加神经性医源性损伤的风险。腓骨腱鞘到腓骨尖远端2 cm和1.5 cm处腓肠神经之间的平均距离分别为9.1±3.5 mm和7.8±3.3 mm。结论从腓腱鞘到腓肠神经的距离从近端到远端减小。随着腓骨腱鞘和腓肠神经之间的距离从近端到远端减小，在更远端进行肌腱镜检查门将增加神经医源性损伤的风险。腓骨腱远端到腓骨尖的2 cm和1.5 cm处腓骨鞘与腓肠神经之间的平均距离分别为9.1±3.5 mm和7.8±3.3 mm。结论从腓腱鞘到腓肠神经的距离从近端到远端减小。随着腓骨腱鞘和腓肠神经之间的距离从近端到远端减小，在更远端进行肌腱镜检查门将增加神经性医源性损伤的风险。
