Abstract

Variations of the calf muscles are rare. One such variant muscle known as the flexor accessories longus seldom encounters in the posterior crural region. This accessory muscle is believed to be a causative factor for swelling or pain in the medial aspect of leg. Therefore prior knowledge of existence of aberrant muscle is pre-requisite for the surgeons, orthoaedicians as well the radiologists while operating and interpreting the swelling in the medial side of leg or pain due to the entrapment of the tendon as in flexor hallucis syndrome. During the routine dissection of the lower limb for the medical undergraduate students, we came across such accessory muscle on the lateral side of the posterior compartment of leg. This variant muscle was present unilaterally and was bipennate origin from the lower part of medial inter-muscular septum and from the lower end of fibula of the right leg. It then passed deep to the flexor retinaculum and on entering the sole of the foot joined with a slip from the tendon of flexor hallucis longus to gain eventual insertion to the flexor digitorum accessories muscle.
