Polydactyly of the foot

Abstract

Fifty-six patients with 72 duplicated toes were analysed. Postaxial duplication accounted for 79%, and the most common anatomical pattern was duplication of the proximal phalanx with a wide metatarsal head. Forty-two patients with 55 duplications were clinically and radiographically evaluated at long-term follow-up (mean 22.5 years). Results were satisfactory in 91% of the patients. Poor results were often associated with preaxial polydactyly because of persistent hallux varus. Surgical treatment is usually straightforward but must be individualized, and some anatomical and surgical details should be considered to obtain a better result.
