Individuals were recruited for participation if the video could be classified by injury mechanism with a high likelihood of sustaining an ankle fracture. Corresponding injury radiographs were obtained. Injury mechanism was classified using the LH system as supination\/external rotation (SER), supination\/adduction (SAD), pronation\/external rotation (PER), or pronation\/abduction (PAB). Corresponding radiographs were classified by the LH system and the AO system.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Thirty injury videos with their corresponding radiographs were collected. Of the video clips reviewed, 16 had SAD mechanisms and 14 had PER mechanisms. There were 26 ankle fractures, 3 nonfractures, and 1 subtalar dislocation. Twelve fractures with SAD mechanisms had corresponding SAD fracture patterns. Five PER mechanisms had PER fracture patterns. Eight PER mechanisms had SER fracture patterns and 1 had SAD fracture pattern. When the AO classification was used, all 12 SAD type injuries had a 44A type fracture, whereas the 14 PER injuries resulted in nine 44B fractures, two 44C fractures, and three 43A fractures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>When injury video clips of ankle fractures were matched to their corresponding radiographs, the LH system was 65% (17\/26) consistent in predicting fracture patterns from the deforming injury mechanism. When the AO classification system was used, consistency was 81% (21\/26). The AO classification, despite its development as a purely radiographic system, correlated with in vivo injuries, as based on observed mechanism of injury, more closely than did the LH system.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence:<\/jats:title>\n                    <jats:p>Level IV, case series.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/1071100713491730","type":"journal-article","created":{"date-parts":[[2013,6,1]],"date-time":"2013-06-01T02:56:58Z","timestamp":1370055418000},"page":"1516-1520","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":41,"title":["Correlation of AO and Lauge-Hansen Classification Systems for Ankle Fractures to the Mechanism of Injury"],"prefix":"10.1177","volume":"34","author":[{"given":"Edward K.","family":"Rodriguez","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Beth Israel Deaconess Medical Center, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John Y.","family":"Kwon","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Massachusetts General Hospital, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lindsay M.","family":"Herder","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Beth Israel Deaconess Medical Center, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul T.","family":"Appleton","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Massachusetts General Hospital, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2013,5,31]]},"reference":[{"key":"bibr1-1071100713491730","doi-asserted-by":"publisher","DOI":"10.1097\/00005131-200604000-00006"},{"key":"bibr2-1071100713491730","doi-asserted-by":"publisher","DOI":"10.1177\/03635465030310041201"},{"key":"bibr3-1071100713491730","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.G.01288"},{"key":"bibr4-1071100713491730","doi-asserted-by":"crossref","unstructured":"Kwon JY, Chacko AT, Kadzielski JJ, A novel methodology for the study of injury mechanism: ankle fracture analysis using injury videos posted on YouTube.com.
