Peroneus tertius is an evolutionary muscle of anterior compartment of leg found exclusively in human being due to their erect posture. The aim of present study is to highlight the variations of Peroneus tertius from academic, phylogenetic and clinical point of view. We dissected both the lower limbs of 100 embalmed apparently normal cadavers. Any variations in Peroneus tertius if observed were meticulously noted. Absence of Peroneus tertius was seen in 16 cases. Peronius tertius was replaced by additional slip from Extensor digitorum longus in 5 cases. Extensive origin was seen in 44 cases. Extended insertion was noted in 4 cases upto the shaft of fifth metatarsal. Insertion to base of fifth metatarsal & medial slip to shaft of forth metatarsal was noted in 3 cases. Knowledge of such variations is important in various surgical procedures as peroneus tertius may be used for tendon transplantations, its correlation with stress fracture and treatment of ankle laxity.
