Treatment of the Mirror Foot with Central Ray Resection: Report of 2 Cases

Abstract

The mirror foot is a rare congenital foot anomaly which is often associated with 6- to 8-toed polydactyly. Postaxial polydactyly is the most common form of this anomaly, while central polydactyly is seen infrequently. We report on 2 cases of the central mirror-foot anomaly. Calcaneus duplication and fibular hypoplasia were present in 1 case. We treated both patients by resecting the middle foot rays and narrowing the foot width through cuneiform excision and use of cerclage wires or heavy suture approximation of the remaining adjacent rays. In the mirror foot, the old and more common treatment was the resection of the border extra toes or rays. Central-ray amputation with dorsal and plantar incisions and narrowing the foot with soft-tissue reduction and cuneiform excision confer excellent functional and cosmetic results.
