The deformity was simulated by sectioning the tendons and ligaments of the ankle and foot that normally support the longitudinal arch. Axial loads of 1,350 N were applied to the foot in a neutral position in both the intact specimen and flatfoot model. The flatfoot condition resulted in significant lateral shifts of 5.28 mm in global contact area and 11.26 mm in the location of peak pressure, and in a small but significant posterior shift of 1.14 mm in global contact area. The flatfoot condition also resulted in a significant, 35%, reduction in contact area. Significant increases in mean pressure, 14%, and peak pressure, 13%, were also found, but were not in proportion to the relatively large decrease in contact area. This suggests a transfer of load off of the talar dome. Increased loading of the lateral facet and fibula are suspected. The lateral shift in the contact region created a local increase in mean contact pressure that may be responsible for long term degenerative changes in patients with this deformity.<\/jats:p>","DOI":"10.1177\/107110070102200312","type":"journal-article","created":{"date-parts":[[2017,1,12]],"date-time":"2017-01-12T20:51:26Z","timestamp":1484254286000},"page":"241-246","source":"Crossref","is-referenced-by-count":51,"title":["The Effects of Adult Acquired Flatfoot Deformity on Tibiotalar Joint Contact Characteristics"],"prefix":"10.1177","volume":"22","author":[{"given":"Mark A.","family":"Friedman","sequence":"first","affiliation":[{"name":"The University of Chicago Medical Center Department of Surgery, Section of Orthopaedics and Rehabilitation Medicine 5841 South Maryland Avenue MC 3079 Chicago, Illinois 60637"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Louis F.","family":"Draganich","sequence":"additional","affiliation":[{"name":"The University of Chicago Medical Center Department of Surgery, Section of Orthopaedics and Rehabilitation Medicine 5841 South Maryland Avenue MC 3079 Chicago, Illinois 60637"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brian","family":"Toolan","sequence":"additional","affiliation":[{"name":"The University of Chicago Medical Center Department of Surgery, Section of Orthopaedics and Rehabilitation Medicine 5841 South Maryland Avenue MC 3079 Chicago, Illinois 60637"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael E.","family":"Brage","sequence":"additional","affiliation":[{"name":"University of San Diego 200 W Arbor Drive, #8894 San Diego, CA 92130-8894"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2001,3,1]]},"reference":[{"key":"bibr1-107110070102200312","doi-asserted-by":"publisher","DOI":"10.1177\/107110079401500307"},{"key":"bibr2-107110070102200312","doi-asserted-by":"publisher","DOI":"10.1002\/jor.1100060609"},{"key":"bibr3-107110070102200312","doi-asserted-by":"publisher","DOI":"10.1177\/036354659302100209"},{"key":"bibr4-107110070102200312","doi-asserted-by":"publisher","DOI":"10.1177\/107110079201300606"},{"key":"bibr5-107110070102200312","doi-asserted-by":"publisher","DOI":"10.7547\/87507315-84-10-491"},{"key":"bibr6-107110070102200312","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198668010-00012"},{"key":"bibr7-107110070102200312","doi-asserted-by":"publisher","DOI":"10.1177\/107110078200200509"},{"key":"bibr8-107110070102200312","doi-asserted-by":"publisher","DOI":"10.1177\/107110079201300204"},{"key":"bibr9-107110070102200312","first-page":"1480","volume-title":"Disorders of the Foot and Ankle","volume":"2","author":"Jahss MH","year":"1991"},{"key":"bibr10-107110070102200312","doi-asserted-by":"publisher","DOI":"10.1177\/107110079801900705"},{"key":"bibr11-107110070102200312","first-page":"46","volume":"181","author":"Mann RA","year":"1983","journal-title":"Clin Orthop"},{"key":"bibr12-107110070102200312","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198567040-00009"},{"key":"bibr13-107110070102200312","first-page":"2","volume":"30","author":"Mueller TJ","year":"1991","journal-title":"J Foot Surg"},{"key":"bibr14-107110070102200312","doi-asserted-by":"publisher","DOI":"10.1177\/107110079501600104"},{"key":"bibr15-107110070102200312","doi-asserted-by":"publisher","DOI":"10.1007\/BF02318871"},{"key":"bibr16-107110070102200312","first-page":"189","volume":"127","author":"Stauffer RN","year":"1977","journal-title":"Clin Orthop"},{"key":"bibr17-107110070102200312","doi-asserted-by":"publisher","DOI":"10.1002\/jor.1100140619"}],"container-title":["Foot &amp; Ankle International"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/107110070102200312","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/107110070102200312","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/107110070102200312","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T21:20:06Z","timestamp":1777411206000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/107110070102200312"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2001,3]]},"references-count":17,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2001,3]]}},"alternative-id":["10.1177\/107110070102200312"],"URL":"https:\/\/doi.org\/10.1177\/107110070102200312","relation":{},"ISSN":["1071-1007","1944-7876"],"issn-type":[{"value":"1071-1007","type":"print"},{"value":"1944-7876","type":"electronic"}],"subject":[],"published":{"date-parts":[[2001,3]]}}}
