Central Polydactyly of the Foot: Surgical Management With Plantar and Dorsal Advancement Flaps

BACKGROUND:Central polydactyly is the least common form of foot polydactyly, and the intercalary location of the duplicated ray makes the surgical exposure, excision, and closure more complex. For these reasons there is little consensus concerning the optimal technique for surgical management. METHODS:A retrospective case series of 22 patients with 27 feet with central polydactyly, treated surgically by the dorsal and plantar advancement flap technique, was performed. Change in width of the forefoot was measured from radiographs by the metatarsal gap ratio. Functional outcomes were assessed by the Foot and Ankle Ability Measure. RESULTS:Signficant narrowing of the forefoot, as measured radiographically by the metatarsal gap ratio, was achieved after surgery (P
