Abstract:"Introduction: Peroneus tertius (PT) is a muscle of the anterior compartment of the leg. The PT muscle originates from the anterior surface of the fibula and the interosseous membrane and inserts into the medial side of the dorsal region of the fifth metatarsal bone. The aim of the study is to study the different variations of the peroneus tertius in south Gujarat population and clinical implication of the study. Results: The peroneus tertius is absent in 5% to 17% of the human white population. The function of the peroneus tertius is eversion and dorsiflexion of the foot. These 2 strength parameters have been identified as important parameters in the development of ankle ligament injuries. Conclusion: Variations observed in the peroneus tertius is not uncommon finding during anatomical dissection or autopsies. Variant origin and absence of PT has functional importance in athletes as it has aprotective role against injuries to talocrural joint in subjects with high functional demand. It is also important for orthopedic surgeons for performing graft operations and transplant surgeries in foot. Variant course of TA is also important for tendon transfer surgeries in Orthopedics."
