Central Mirror Foot: Treatment and Review of the Literature

Abstract

Mirror foot is a rare abnormality which presents as a preaxial, postaxial, or central polydactyly of the foot. The latter is encountered infrequently. We describe the case of a central mirror foot. Our patient had eight digits of a central ray pattern type with fully developed metatarsal, proximal, middle, and distal phalanges, as well as a medial toe syndactyly. He had no tarsal bone duplications. He was treated by central ray resection via double V-shaped incisions on the dorsal and plantar aspects of the foot, while preserving the medial and lateral rays. The results were satisfactory. We describe the technique and attempt a review of the literature.

Keywords: central ray; mirror foor; polydactyly.

XR left central ray mirror foot with eight digits portraying fully developed metatarsal (white arrow), proximal, middle, and distal phalanges (green arrows), except for the fourth toe from the medial side which appeared to be missing a middle phalanx (pink arrows) and had a dysplastic metatarsal (blue arrow), in comparison to the rest (white arrow). This digit was similar to a great toe.
