A surgically created transverse fibula osteotomy with up to 6 mm of displacement did not cause a significant change in the contact area. Sectioning of the deltoid ligament, regardless of fibular displacement, created a 15% to 20% decrease in the contact area ( P &lt; .001). This model represents a clinically relevant situation, as it examines motion of an unconstrained, axillary loaded ankle. Additional medial side disruption increases ankle instability by allowing anterior and lateral translation of the talus out of the mortise. Isolated lateral malleolar displacement does not appear to cause ankle instability.<\/jats:p>","DOI":"10.1177\/107110079101100407","type":"journal-article","created":{"date-parts":[[2013,3,3]],"date-time":"2013-03-03T03:31:12Z","timestamp":1362281472000},"page":"222-227","source":"Crossref","is-referenced-by-count":95,"title":["Tibio-Talar Stability in Bimalleolar Ankle Fractures: A Dynamic In Vitro Contact Area Study"],"prefix":"10.1177","volume":"11","author":[{"given":"Hugh J.","family":"Clarke","sequence":"first","affiliation":[{"name":"From The Johns Hopkins University, Francis Scott Key Medical Center Baltimore, Maryland."},{"name":"Research Fellows in Adult Reconstructive Surgery."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James D.","family":"Michelson","sequence":"additional","affiliation":[{"name":"From The Johns Hopkins University, Francis Scott Key Medical Center Baltimore, Maryland."},{"name":"Assistant Professor of Orthopaedics."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Quentin G.K.","family":"Cox","sequence":"additional","affiliation":[{"name":"From The Johns Hopkins University, Francis Scott Key Medical Center Baltimore, Maryland."},{"name":"Research Fellows in Adult Reconstructive Surgery."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Riyaz H.","family":"Jinnah","sequence":"additional","affiliation":[{"name":"From The Johns Hopkins University, Francis Scott Key Medical Center Baltimore, Maryland."},{"name":"Assistant Professor of Orthopaedics, Johns Hopkins University, Francis Scott Key Medical Center, 4940 Eastern Avenues Baltimore, Maryland 21224."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1991,2,1]]},"reference":[{"key":"bibr1-107110079101100407","doi-asserted-by":"publisher","DOI":"10.3109\/17453678508994329"},{"key":"bibr2-107110079101100407","first-page":"17","volume":"199","author":"Bauer M.","year":"1985","journal-title":"A controlled study.
