Abstract
Objective
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.
Methods
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.
Results
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.
