The management of mirror foot polydactyly: A case report

Abstract

Background Mirror foot or mirror image duplication of the foot is an extreme form and very rare congenital anomaly. There are limited management recommendations, and most cases are treated before walking age. We present the clinical findings, surgical treatment, and results of a rare case of mirror foot polydactyly. Case presentation A five-month-old girl with bilateral mirror foot was referred to our orthopaedic department. She was born full-term by the caesarian section and there was no family history of similar skeletal abnormalities and no history of drug or radiation exposure during gestation. The child had eight toes on the right foot and seven toes on the left with fully developed metatarsal, proximal, middle, and distal phalanges. Radiographs confirmed the diagnosis of mirror foot with a full complement of normal lateral toes and three additional complete rays medial to the right foot and two additional complete rays medial to the left foot. The patient underwent ray resection and concurrent reconstruction of the medial arch of the foot. A medial longitudinal incision was used to excised the right medial three rays and left medial two rays. The target of this surgical intervention was for aesthetic or cosmetic reasons and enabling the patient to allow shoe wear. Conclusion Mirror-foot abnormalities are distinctly uncommon entities and represent extreme forms of congenital duplication of the preaxial polydactyly spectrum. Treatment on age of five-month-old with medial longitudinal incision had a satisfying clinical and radiological results.

“…The mirror foot consists of seven or more toes; it is also described as preaxial or central. It may be part of a syndrome such as VACTERL, Martin, Lauren Sandrow, or fibular dimelia [1][2][3][4][5][6][7][8][9].…”
