The literature is uncertain about which type of osteotomy and fixation is best. The objective of this study was to compare, in cadaveric specimens, the oblique and chevron medial malleolar osteotomies and their fixation with either 2 or 3 screws, evaluating the possibility of articular displacement. We hypothesize that the chevron osteotomy results in a lower chance of articular displacement at the end of the procedure than the oblique osteotomy. Our second hypothesis is that fixation with 3 screws also reduces the risk of articular displacement compared with 2 screws.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Forty anatomical fresh\u2011frozen specimens were analyzed and divided into 4 groups (10\u2009per group): oblique osteotomy fixed with 2 or 3 screws and chevron osteotomy fixed with 2 or 3 screws. One fracture occurred in the chevron osteotomy group with 3 screws, leaving 39 specimens for analysis. After osteotomies and fixation, the talus was removed, and articular displacement (step\u2011off) of the distal tibia was assessed using a digital caliper.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The results indicated a lower incidence of articular displacement in chevron osteotomy (21.1%) compared with oblique osteotomy (50%). Fixation with 3 screws showed a lower rate of incongruence (21.1%) compared with 2 screws (50%). When the type of osteotomy and fixation were combined the chevron osteotomy fixed with 3 screws had no measurable articular displacement in this cadaveric model.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>In this cadaveric surgical technique model, a chevron medial malleolar osteotomy fixed with 3 screws showed no measurable articular displacement and overall had a lower risk of articular step\u2011off compared with oblique osteotomy and 2\u2011screw fixation.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/10711007261422238","type":"journal-article","created":{"date-parts":[[2026,3,17]],"date-time":"2026-03-17T11:21:51Z","timestamp":1773746511000},"page":"628-635","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Medial Malleolar Osteotomy: The Influence of 2 Types of Osteotomies and 2 Fixation Methods on Articular Displacement in Fresh-Frozen Cadaveric Specimens"],"prefix":"10.1177","volume":"47","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9411-9376","authenticated-orcid":false,"given":"Marco T\u00falio","family":"Costa","sequence":"first","affiliation":[{"name":"Irmandade da Santa Casa de Miseric\u00f3rdia de S\u00e3o Paulo, S\u00e3o Paulo, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jordanna Maria Pereira","family":"Bergamasco","sequence":"additional","affiliation":[{"name":"Irmandade da Santa Casa de Miseric\u00f3rdia de S\u00e3o Paulo, S\u00e3o Paulo, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7696-2220","authenticated-orcid":false,"given":"No\u00e9","family":"De Marchi Neto","sequence":"additional","affiliation":[{"name":"Irmandade da Santa Casa de Miseric\u00f3rdia de S\u00e3o Paulo, S\u00e3o Paulo, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eduardo Sadao","family":"Yonamine","sequence":"additional","affiliation":[{"name":"Irmandade da Santa Casa de Miseric\u00f3rdia de S\u00e3o Paulo, S\u00e3o Paulo, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claudio","family":"Santili","sequence":"additional","affiliation":[{"name":"Irmandade da Santa Casa de Miseric\u00f3rdia de S\u00e3o Paulo, S\u00e3o Paulo, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2026,3,17]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00590-019-02524-1"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00590-024-03933-7"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1177\/1071100716628912"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1177\/1938640012474035"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00402-010-1227-8"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546512461132"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-012-2050-2"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13018-017-0610-3"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1177\/107110070602701203"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-015-3591-y"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12891-024-07541-8"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/s1083-7515(02)00037-2"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.1177\/1947603520961169"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.1053\/j.jfas.2011.10.009"},{"key":"e_1_3_2_16_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546506287296"},{"key":"e_1_3_2_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.otsr.2021.103070"},{"key":"e_1_3_2_18_2","doi-asserted-by":"publisher","DOI":"10.1177\/1947603511400726"},{"key":"e_1_3_2_19_2","doi-asserted-by":"publisher","DOI":"10.1097\/00132587-200212000-00011"}],"container-title":["Foot &amp;
