Congenital diplopodia–A rare case of duplicated lower limb: A case report

INTRODUCTION AND IMPORTANCE: Diplopodia is an extremely rare case in medical history, with an even fewer cases being reported in literature. We intended to enrich the literature about diplopodia with our own case report. CASE PRESENTATION: We present a case about A boy, aged one year and four months old brought by his mother to the hospital with a chief complaint of a duplicated foot in his right lower leg. Physical examination demonstrated a normal left lower extremity and a relatively well-developed duplicate foot emanating from the posterior-lateral aspect of the mid-lower right leg. CLINICAL DISCUSSION: Diplopodia consists of partial duplication of the foot, with or without hypoplasia or positional abnormality of the ipsilateral tibia and fibula. It must be differentiated from polydactyly where the additional structures consist of toes that may or may not have corresponding metatarsals but are devoid of tarsal bone. Treatment should be considered case-by-case basis and tailored appropriately to suit individual needs and circumstances. CONCLUSION: In our case, operative treatment was done at an early walking age to provide plantigrade, functional foot. Timely surgical intervention will enable patient to adapt over time. The secondary aim is to reconstruct the foot to be more acceptable aesthetically.
