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

The TN most commonly bifurcates above the MCA, that is, within the tarsal tunnel. This anatomical consistency is clinically relevant during surgical procedures such as tarsal tunnel release and nerve block administration. However, anatomical variants such as trifurcation or accessory branches are not uncommon and must be anticipated to avoid iatrogenic injury. Accurate knowledge of TN bifurcation patterns and their relationship to the MCA is essential for clinical practice surgeons, anesthesiologists, and radiologists.
