A Rare Anatomical Variation of Common Tendinous Insertion of Tibialis Posterior and Fibularis Longus: A Case Report

The tibialis posterior muscle is the deep muscle of the back of the leg and the fibularis longus is the muscle of the lateral compartment of the leg.These muscles impact the maintenance of the longitudinal and transverse arch of the foot.In This case, it was observed that the common tendinous insertion of tibialis posterior and fibularis longus was identified in the right lower limb during routine dissection at the National Institute of Ayurveda, Jaipur.The subject was a 55-year-old male cadaver of north Indian origin.Numerous pathologies could be linked with the common tendinous insertion of these two muscles, tibialis posterior and fibularis longus.This study aims to investigate anatomical variations of the distal insertion of the tibialis posterior and fibularis longus.
