title: A rare case of variant morphology of peroneus tertius muscle.
abstract: Peroneus tertius (PT) is frequently used as a free muscle flap to treat the soft tissue defects and osteomyelitis, in the lower limb as it is functionally insignificant while balancing the foot during walking. The morphology of the PT is highly variable. In the present case we report a rare case of unusual morphology of the PT in a formalin embalmed male cadaver. At the level of ankle, PT divided into three tendons; two of them were inserted to the base of the distal phalanx of the fifth toe and base of the fifth metatarsal bone respectively. The smaller third tendon was attached to the fascia covering the capsule of the ankle joint. Further, extensor digitorum longus (EDL) gave only three tendinous slips for the second, third and fourth toes.
