However, most classification systems are based solely on morphology and tend to be inaccurate and less relevant to surgical methods and results. The purpose of this study is to present our new classification of polydactyly of the foot, which can serve as a predictor of treatment and prognosis.<\/jats:p>\n Methods To find a correlation between the various morphologic traits of polydactyly of the foot and the treatment plan and outcomes, we reviewed 532 cases of polydactyly of the foot in 431 patients treated in our hospital, expanding on our previous study that described polydactyly based on the importance of metatarsal bone status and varus deformity. The records of patients were evaluated and compared with previous studies at other centers.<\/jats:p>\n Results Unsatisfactory results were seen in 36 cases, which included 5 cases of incomplete separation due to syndactylism, 23 cases of axis deviation, and 8 cases of remnants of extra-digit metatarsal bones. The locus of the polydactyly, or the digit which was involved, did not seem to affect the final postoperative outcomes in our study. Three factors-syndactylism, axis deviation, and metatarsal extension-are the major factors related to treatment strategy and prognosis. Therefore, we developed a new classification system using three characters (S, A, M) followed by three groups (0, 1, 2), to describe the complexity of polydactyly of the foot, such as S1A2M2.<\/jats:p>\n Conclusions Our new classification could provide a communicable description to help determine the surgical plan and predict outcomes.<\/jats:p>","DOI":"10.5999\/aps.2013.40.3.232","type":"journal-article","created":{"date-parts":[[2013,5,27]],"date-time":"2013-05-27T10:23:51Z","timestamp":1369650231000},"page":"232-237","source":"Crossref","is-referenced-by-count":48,"title":["New Classification of Polydactyly of the Foot on the Basis of Syndactylism, Axis Deviation, and Metatarsal Extent of Extra Digit"],"prefix":"10.1055","volume":"40","author":[{"given":"Hyo Hyun","family":"Seok","sequence":"additional","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery, Seoul National University College of Medicine, Seoul, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji Ung","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery, Seoul National University College of Medicine, Seoul, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung Tack","family":"Kwon","sequence":"additional","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery, Seoul National University College of Medicine, Seoul, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2022,5,1]]},"reference":[{"key":"ref1","first-page":"501","article-title":"Simple classification of foot polydactyly based on the status of metatarsal bone and varus deformity","volume":"31","author":"WG Son","year":"2004","journal-title":"J Korean Soc Plast Reconstr Surg"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"474","DOI":"10.1016\/S0363-5023(87)80027-8","article-title":"Polydactyly of the hands and feet","volume":"12","author":"T Miura","year":"1987","journal-title":"J Hand Surg Am"},{"key":"ref3","first-page":"317","article-title":"Clinical study on polydactyly of the foot","volume":"24","author":"HJ Kim","year":"1997","journal-title":"J Korean Soc Plast Reconstr Surg"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"909","DOI":"10.1016\/S0030-5898(20)32238-0","article-title":"Problems in polydactyly of the foot","volume":"7","author":"EA Venn-Watson","year":"1976","journal-title":"Orthop Clin North Am"},{"key":"ref5","doi-asserted-by":"crossref","first-page":"446","DOI":"10.1097\/01241398-198507000-00012","article-title":"Polydactyly of the foot","volume":"5","author":"DA Phelps","year":"1985","journal-title":"J Pediatr Orthop"},{"key":"ref6","doi-asserted-by":"crossref","first-page":"251","DOI":"10.1097\/00006534-198702000-00018","article-title":"Treatment of preaxial polydactyly of the foot","volume":"79","author":"K Masada","year":"1987","journal-title":"Plast Reconstr Surg"},{"key":"ref7","doi-asserted-by":"crossref","first-page":"856","DOI":"10.1097\/00006534-199205000-00014","article-title":"Polydactyly of the foot: an analysis of 265 cases and a morphological classification","volume":"89","author":"H Watanabe","year":"1992","journal-title":"Plast Reconstr Surg"},{"key":"ref8","doi-asserted-by":"crossref","first-page":"216","DOI":"10.1097\/01.bpb.0000192055.60435.31","article-title":"Polydactyly of the foot","volume":"16","author":"S Turra","year":"2007","journal-title":"J Pediatr Orthop B"},{"key":"ref9","doi-asserted-by":"crossref","first-page":"34","DOI":"10.1054\/bjps.2000.3453","article-title":"Polydactyly of the feet in children: suggestions for surgical management","volume":"54","author":"SE Morley","year":"2001","journal-title":"Br J Plast Surg"},{"key":"ref10","doi-asserted-by":"crossref","first-page":"334","DOI":"10.1007\/BF00381058","article-title":"Classification of polydactyly of the hands and feet","volume":"107","author":"W Blauth","year":"1988","journal-title":"Arch Orthop Trauma Surg"},{"key":"ref11","first-page":"175","article-title":"The results of surgery for polydactyly of the thumb.
