An Anatomical Study on the Tibial Nerve Bifurcation Level in Relation to the Malleolar-Calcaneal Axis and Its Clinical Significance.

Objective: The objective of this study was to examine the level at which the tibial nerve (TN) bifurcates about the malleolar-calcaneal axis (MCA), a key anatomical reference approximating the inferior margin of the flexor retinaculum, to document anatomical variations with potential clinical and surgical significance.

Methodology: A descriptive cross-sectional study was conducted on 60 lower limbs obtained from formalin-embalmed adult human cadavers. Following standard anatomical protocols, dissections were performed to trace the TN from its origin to its terminal branches.
