Mirror foot: treatment of three cases and review of the literature

Abstract

Purpose To describe three cases of mirror foot and to develop a new classification of the mirror feet with an emphasis on their treatment. Methods Surgical treatment was performed on three patients with mirror foot. Mirror feet in the English literature were surveyed and cases found in PubMed as well as our three cases were classified according to a new classification that was an analogy of the mirror hand classification proposed by Al-Qattan et al. (J Hand Surg Br 23:534–536, 1998). Results All three cases obtained satisfactory outcome after the treatment. In addition to these cases, 28 mirror feet were well described in the English literature, among which only seven cases have been documented for their treatment. All of the cases could be assigned to one of the categories of the proposed classification. Conclusion Mirror foot is a very rare congenital deformity of the foot. We successfully treated three novel cases of mirror feet. A classification of the mirror feet proposed in this article was useful in order to understand its nature and obtain a guideline for its treatment.
