Abstract

Purpose: We investigate the characteristic morphologic features and suggest proper treatment of postaxial polydactyly of the foot Materials and Methods: We analysed 37 cases of postaxial polydactyly. Mean post operative follow up period was 2 years 10 months. We analysed them according to morphological, radiological and operative findings. Patients were classified into extra 5th toe polydactyly and extra 6th toe polydactyly based on the abnormal extradigit, and subdivided into joint origin type, bone origin type and floating type based on duplication pattern. Results: 23 cases were extra 5th toe polydactyly and 14 cases were extra 6th toe polydactyly. Most common types were metatarsophalangeal joint origin type of extra 6th toe polydactyly. Compared with extra 5th toe polydactyly, extra 6th toe polydactyly originated from more proximal part and had not syndactylism. Conclusion: As the duplication level was more distal, degree of syndactylism and nail union was more severe. In case of syndactyly between 5th and 6th toe, abnormal extradigit was 5th toe.
