Abstract

Purpose: There are no data on the connection of the saphenous nerve (SN), located on the medial side of the foot, with the terminal branches of the superficial fibular nerve. The aim of this study is to reveal the variation that surgeons should pay attention to for anesthesia applied in foot surgeries.

Methods: In this study, the left foot of a 70-year-old female cadaver fixed with formalin was dissected. The distance to the medial malleolus and the incision line was recorded using digital caliper to determine the reference points in the resulting variation.

Results: It was observed that a branch from the SN, which arose from the SN and proceeded anteriorly to the upper part of the medial malleolus and continued towards the dorsum of the foot, hooked with a branch from the medial dorsal cutaneous nerve (MDCN). The branches arising from this hook were distributed on the medial edge of the foot up to the proximal metatarsophalangeal joint I. The distance of this nerve connection to the medial malleolus is 91.14 mm, and the distance to the incision line is 15.76 mm.

Conclusions: It is suggested that the case presented as an unusual SN variation, which may affect the success of local anesthesia in invasive procedures to the medial part of the foot and could be considered in the evaluation of sensory loss after anteromedial surgical approach to the ankle, should be included in the classification of the cutaneous innervation pattern of the foot.

背内侧皮神经与隐神经的连接1例。

目的：没有关于位于脚内侧的隐神经（SN）与腓浅神经终末支的连接的数据。本研究的目的是揭示外科医生在足部手术中应用麻醉时应注意的变化。方法：对一具福尔马林固定的70岁女性尸体的左脚进行解剖。使用数字卡尺记录到内踝和切口线的距离，以确定结果变化中的参考点。结果：观察到SN的一个分支与内侧背侧皮神经（MDCN）的一个支钩住，该分支起源于SN，向前延伸至内踝上部，并继续向足背延伸。从该钩产生的分支分布在足内侧边缘，一直到跖骨近端关节I。该神经连接到内踝的距离为91.14mm，到切口线的距离为15.76mm，这可能影响足部内侧侵入性手术中局部麻醉的成功，并可在评估踝关节前内侧手术入路后的感觉丧失时考虑。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
