Flexor Digitorum Longus Muscle — an Unusual Presentation; Anatomy and Clinical Significance, A case report

Understanding muscle architecture of the foot may assist in the design of surgical procedures such as tendon transfer, biomechanical modeling of the foot, prosthesis design, and analysis of foot function. This paper primarily focuses on the variation of Flexor Digitorum Longus and Brevis muscles of foot. Sixty inferior extremities were dissected. While dissecting a body of adult female we observed a small muscle belly taking origin from the medial and lateral processes of the calcaneal tuberosity and get inserted in the distal phalanx of the little toe of right foot. The 4th tendon of the Flexor Digitorum Brevis muscle was absent and the respective tendon of the Flexor Digitorum Longus muscle to the little toe was atrophied in same foot. This additional muscle belly is pierced by one of branch of lateral planter nerve. The importance of such variations is to be kept in mind during radio-diagnostic procedures and surgical interventions.
