Abstract

Introduction: Mirror foot (or duplicated foot) is an extremely rare congenital disorder that is seldom discussed in published report. In this clinical description of mirror foot, we aim to enrich the current literature on mirror foot and provide an efective approach and treatment for mirror foot treatment application.

Presentation of case: We present a clinical case of a 12-month-old male child with a mirror foot condition accompanied by fbular hypoplasia in a child with no other organ or physical abnormalities. Imaging diagnosis revealed a foot with eight toes duplicated on the outer side. The incomplete foot exhibited hypoplasia of the toe bones and corresponding metatarsal bones, as well as a bony mass at the ankle associated with fbular hypoplasia. This mirro foot have a common heel. The vascular supply is provided by an abnormal branch of the posterior tibial artery. The patient has equinovarus deformity in the right foot with four extra toes. There is also a marked shortening of the right leg with a fxed 20° fexion deformity at the knee, but the child can still attempt to stand with a slight degree of limitation.

Discussion: Mirror foot involves the duplication of a part of the foot, with or without reduced development or abnormal positioning of the tibia and fbula on the same side. It needs to be distinguished from polydactyly, meaning that the toes may or may not have corresponding foot bones but do not have accessory bones in the foot. We performed surgery to remove the outer half of the foot, reconstructing the bone structure based on 3D computed tomography images and vascular sources.

Conclusion: Mirror foot is a very rare congenital deformity of the foot. Surgery was performed just before the child learned to walk. Treatment should be considered on a case-by-case basis and adjusted accordingly. Post-surgery, satisfactory results were achieved in terms of both function and aesthetics of the foot.
