Follow-up averaged 21 years. Duplication may be classified into three groups: simple hallucal duplication, a transitional type with a short thick first metatarsal, and complete first ray duplication. Routine removal of the most medial hallux or ray is to be avoided. Careful preoperative assessment is necessary to compare hallucal function, cosmesis, and metatarsal weightbearing. Surgery should also correct the associated congenital hallux varus. Surgical complications include functionless hallucis from inappropriate selection and medial soft tissue contractures with either recurrence of the hallux varus or the gradual development of a hallux varus interphalangeus.<\/jats:p>","DOI":"10.1177\/107110078400500104","type":"journal-article","created":{"date-parts":[[2013,3,3]],"date-time":"2013-03-03T03:24:58Z","timestamp":1362281098000},"page":"26-34","source":"Crossref","is-referenced-by-count":7,"title":["Duplication of the Hallux"],"prefix":"10.1177","volume":"5","author":[{"given":"Melvin H.","family":"Jahss","sequence":"first","affiliation":[{"name":"Mount Sinai Medical School, and Chief of Orthopaedic Foot Services, Hospital for Joint Diseases-Orthopaedic Institute and Mount Sinai Hospital, New York, New York."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Nelson","sequence":"additional","affiliation":[{"name":"Chief Orthopaedic Resident, Hospital for Joint Diseases-Orthopaedic Institute, New York, New York."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1984,7,1]]},"reference":[{"key":"bibr1-107110078400500104","first-page":"397","volume":"16","author":"Boheme P.","year":"1929","journal-title":"Rev.
