An unusual case of mixed polydactyly of foot

Abstract

A common congenital anomaly, polydactyly refers to supernumerary digits of the hand or foot, the incidence of which varies widely according to race, geographical location, familial syndromes and other environmental factors. The foot tends to be more rarely involved than the hand. These images depict a 60-year-old Hindu male with polydactyly of the right foot since birth. Digital radiography of the right foot showed a combination of Y-shaped metatarsal, T-shaped metatarsal, block metatarsal and duplicated rays. There was no sign or symptom of a syndromic anomaly. The disorder appeared to be purely sporadic in nature. The patient displayed unilateral polydactyly with eight digits that included a combination of Yshaped metatarsal, T-shaped metatarsal, block metatarsal and duplicated rays; this is an uncommon presentation. Polydactyly of the foot is a rare disorder which may present sporadically, or in conjunction with familial syndromes; hence, accurate, genetic diagnosis is essential for proper management. Thorough preoperative radiological and anatomical evaluation is mandatory for effective reconstruction of the digit.
