Hemimetatarsal transfer: a unique solution for postaxial metatarsal duplication

Many operations have been described for the reconstructive treatment of foot congenital anomalies involving multiplication of toes and metatarsi. We describe a surgical procedure designed to solve the problem of postaxial polydactily with complete duplication of metatarsi. We successfully performed hemimetatarsal transposition of the hypoplastic metatarsal bone with its intact metatarso-phalangial joint to the base of the extra metatarsus. We achieved good alignment of the lateral ray with restoration of the metatarsal weight-bearing touch points. Functional and cosmetic results of the procedure were excellent.
