Determine, through dissection in fresh cadavers, the topographic anatomy of the tibial nerve and its branches at the ankle, in relation to the tarsal tunnel.
Bilateral dissections were performed on 26 fresh cadavers and the locations of the tibial nerve bifurcation and its branches were measured in millimeters. For the calcaneal branches, the amount and their respective nerves of origin were also analyzed.
The tibial nerve bifurcation occurred under the tunnel in 88% of the cases and proximally in 12%. As for the calcaneal branches, the medial presented with one (58%), two (34%) and three (8%) branches, with the most common source occurring in the tibial nerve (90%) and the lower with a single branch per leg and lateral plantar nerve as the most common origin (70%). Level of Evidence, V Expert opinion .
通过对新鲜尸体进行解剖，确定胫神经及其在踝关节处分支相对于跗管的局部解剖结构。
对26具新鲜尸体进行双侧解剖，并以毫米为单位测量胫神经分叉及其分支的位置。对于跟骨分支，还分析了其数量及其各自的神经起源。
88%的病例中胫神经分叉发生在跗管下方，12%发生在近端。至于跟骨分支，内侧有一支（58%）、两支（34%）和三支（8%）分支，最常见的来源是胫神经（90%），较少见的是每条腿有一支且以外侧足底神经为最常见起源（70%）。证据级别，V专家意见。
