The study included clinical data of 32 patients (54 feet) who had completed a 2-year follow-up, and radiological data of these 32 and other 29 patients (50 feet) for a total of 61 patients (104 feet, 53 right and 51 left). There were 59 females and two males with ages varying from 11 to 66 years. According to the AOFAS Hallux Rating, the preoperative average score (50) improved to 90 (average score after the surgery). The hallux valgus angle was improved from an average of 25\u00b0 to 14\u00b0, the first intermetatarsal angle from 12\u00b0 to 8\u00b0 and the DMAA from 15\u00b0 to 5\u00b0. At the end of treatment, 94% of patients were classified as having grade 0 or I sesamoid lateral sub-luxation. Given improvement in angles and 90% of patients satisfied with an average AOFAS postoperative score of 90, the technique seems indicated for treatment of symptomatic hallux valgus deformity with increased DMAA.<\/jats:p>","DOI":"10.1177\/107110070202300903","type":"journal-article","created":{"date-parts":[[2017,1,13]],"date-time":"2017-01-13T14:52:01Z","timestamp":1484319121000},"page":"792-798","source":"Crossref","is-referenced-by-count":73,"title":["Biplanar Chevron Osteotomy"],"prefix":"10.1177","volume":"23","author":[{"given":"Caio","family":"Nery","sequence":"first","affiliation":[{"name":"Foot and Ankle Clinic, Federal University of S\u00e3o Paulo - Escola Paulista de Medicina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rui","family":"Barroco","sequence":"additional","affiliation":[{"name":"Foot and Ankle Clinic, Federal University of S\u00e3o Paulo - Escola Paulista de Medicina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cibele","family":"R\u00e9ssio","sequence":"additional","affiliation":[{"name":"Foot and Ankle Clinic, Federal University of S\u00e3o Paulo - Escola Paulista de Medicina"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2002,9,1]]},"reference":[{"key":"bibr1-107110070202300903","doi-asserted-by":"crossref","first-page":"20","DOI":"10.1097\/00003086-198106000-00007","volume":"157","author":"Austin DW","year":"1981","journal-title":"Clin Orthop"},{"key":"bibr2-107110070202300903","doi-asserted-by":"publisher","DOI":"10.1177\/107110079701800405"},{"issue":"5","key":"bibr3-107110070202300903","first-page":"450","volume":"30","author":"Bar-David T.","year":"1991","journal-title":"J Foot Surg"},{"key":"bibr4-107110070202300903","doi-asserted-by":"publisher","DOI":"10.1016\/S1067-2516(97)80004-X"},{"key":"bibr5-107110070202300903","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.76B2.8113277"},{"issue":"4","key":"bibr6-107110070202300903","first-page":"382","volume":"32","author":"Bruyn JM","year":"1993","journal-title":"J Foot Ankle Surg"},{"issue":"10","key":"bibr7-107110070202300903","first-page":"776","volume":"95","author":"Chen YJ","year":"1996","journal-title":"J Formos Med Assoc"},{"key":"bibr8-107110070202300903","doi-asserted-by":"publisher","DOI":"10.1177\/107110079801900902"},{"key":"bibr9-107110070202300903","doi-asserted-by":"publisher","DOI":"10.1177\/107110079701800802"},{"key":"bibr10-107110070202300903","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199606000-00018"},{"key":"bibr11-107110070202300903","doi-asserted-by":"publisher","DOI":"10.1177\/107110079501601104"},{"key":"bibr12-107110070202300903","doi-asserted-by":"publisher","DOI":"10.1177\/107110079801900108"},{"key":"bibr13-107110070202300903","doi-asserted-by":"publisher","DOI":"10.1177\/107110079401501202"},{"key":"bibr14-107110070202300903","doi-asserted-by":"publisher","DOI":"10.1177\/107110079601700603"},{"issue":"6","key":"bibr15-107110070202300903","first-page":"615","volume":"31","author":"Fox IM","year":"1992","journal-title":"J Foot Surg"},{"key":"bibr16-107110070202300903","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199710000-00008"},{"issue":"5","key":"bibr17-107110070202300903","first-page":"512","volume":"31","author":"Hanft JR","year":"1992","journal-title":"J Foot Surg"},{"key":"bibr18-107110070202300903","doi-asserted-by":"publisher","DOI":"10.1177\/107110078500500604"},{"key":"bibr19-107110070202300903","doi-asserted-by":"publisher","DOI":"10.1177\/107110079101200201"},{"key":"bibr20-107110070202300903","first-page":"44","volume":"142","author":"Johnson KA","year":"1978","journal-title":"Clin Orthop"},{"key":"bibr21-107110070202300903","doi-asserted-by":"publisher","DOI":"10.1177\/107110079401500701"},{"issue":"2","key":"bibr22-107110070202300903","first-page":"333","volume":"76","author":"Klosok JK","year":"1994","journal-title":"A prospective randomised trial.
