Polydactyly of the foot.
One hundred twenty-five patients with 194 supernumerary toes were analyzed. Postaxial polydactyly accounted for 79%. Duplication at the proximal phalanx with either a block metatarsal or a wide metatarsal head was the most common anatomical pattern. Sixty-one patients with 97 duplications evaluated at an average follow-up of 15.1 years postoperatively had 94% excellent or good results. Poor results were often associated with preaxial duplications and persistent hallux varus. Patients with central duplications often had a persistently wide forefoot. Surgical treatment is usually straightforward, but must be individualized. Preoperative radiologic assessment is mandatory. Certain technical considerations are related to better results.
