The purpose of this study was to report our results with this procedure. Materials and Methods: From January 2000 until December 2006, 23 feet (13 patients) with an increased DMAA were operated upon by the same surgeon using a biplanar chevron osteotomy. The technique was modified making the plantar cut more horizontal and only removing a wedge from the dorsal cut. Clinical and radiographic evaluation was made after a mean followup of 56 months. The AOFAS score for the hallux was used and angular deformities were measured. The patients had a mean age of 51 years and were all female. Results: A good functional result was achieved with a mean AOFAS score of 87. An improvement of the angular deformities was noted in all patients. The mean hallux valgus angle improved from 28 degrees pre-op to 14 degrees post-op, the intermetatarsal angle from 12 degrees to 7 degrees and the DMAA from 20 degrees to 7 degrees. All patients except one were satisfied with the outcome of the procedure. Minimally symptomatic AVN of the metatarsal head was observed in one foot. Conclusions: We conclude that this procedure is a good choice for the treatment of symptomatic hallux valgus with an increased DMAA, producing a good clinical and radiographic result. <\/jats:p><jats:p> Level of Evidence: IV, Retrospective Case Series <\/jats:p>","DOI":"10.3113\/fai.2009.1149","type":"journal-article","created":{"date-parts":[[2009,12,11]],"date-time":"2009-12-11T18:23:17Z","timestamp":1260555797000},"page":"1149-1153","source":"Crossref","is-referenced-by-count":41,"title":["Modified Biplanar Chevron Osteotomy"],"prefix":"10.1177","volume":"30","author":[{"given":"Nuno M.","family":"Corte-Real","sequence":"first","affiliation":[{"name":"Lisboa, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rodrigo M.","family":"Moreira","sequence":"additional","affiliation":[{"name":"Lisboa, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2009,12,1]]},"reference":[{"key":"bibr1-FAI.2009.1149","doi-asserted-by":"crossref","first-page":"25","DOI":"10.1097\/00003086-198106000-00007","volume":"157","author":"Austin DW","year":"1981","journal-title":"Clin Orthop."},{"key":"bibr2-FAI.2009.1149","doi-asserted-by":"publisher","DOI":"10.1177\/107110079801900902"},{"key":"bibr3-FAI.2009.1149","doi-asserted-by":"publisher","DOI":"10.1177\/107110079701800802"},{"key":"bibr4-FAI.2009.1149","first-page":"270","volume-title":"Surgery of the Foot and Ankle","author":"Coughlin MJ","year":"1999","edition":"7"},{"key":"bibr5-FAI.2009.1149","doi-asserted-by":"publisher","DOI":"10.1177\/107110079902001202"},{"key":"bibr6-FAI.2009.1149","doi-asserted-by":"publisher","DOI":"10.1177\/107110070102200503"},{"key":"bibr7-FAI.2009.1149","doi-asserted-by":"publisher","DOI":"10.1177\/107110078500500604"},{"key":"bibr8-FAI.2009.1149","first-page":"44","volume":"142","author":"Johnson KA","year":"1978","journal-title":"Clin Orthop."},{"key":"bibr9-FAI.2009.1149","doi-asserted-by":"publisher","DOI":"10.1177\/107110079401500701"},{"key":"bibr10-FAI.2009.1149","doi-asserted-by":"publisher","DOI":"10.1177\/107110070502600705"},{"key":"bibr11-FAI.2009.1149","doi-asserted-by":"publisher","DOI":"10.1177\/107110079701800502"},{"key":"bibr12-FAI.2009.1149","doi-asserted-by":"publisher","DOI":"10.1177\/107110079101200102"},{"key":"bibr13-FAI.2009.1149","doi-asserted-by":"publisher","DOI":"10.1177\/107110070202300903"},{"key":"bibr14-FAI.2009.1149","doi-asserted-by":"publisher","DOI":"10.1177\/107110079201300702"},{"key":"bibr15-FAI.2009.1149","doi-asserted-by":"publisher","DOI":"10.1177\/107110079701800302"}],"container-title":["Foot &amp; Ankle International"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3113\/FAI.2009.1149","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.3113\/FAI.2009.1149","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3113\/FAI.2009.1149","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,11]],"date-time":"2025-03-11T09:21:23Z","timestamp":1741684883000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.3113\/FAI.2009.1149"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,12]]},"references-count":15,"journal-issue":{"issue":"12","published-print":{"date-parts":[[2009,12]]}},"alternative-id":["10.3113\/FAI.2009.1149"],"URL":"https:\/\/doi.org\/10.3113\/fai.2009.1149","relation":{},"ISSN":["1071-1007","1944-7876"],"issn-type":[{"value":"1071-1007","type":"print"},{"value":"1944-7876","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,12]]}}}
