Thirty-nine cases (76.4 %) had multiple joint (at least 2) instability. In the preoperative radiologic findings, C1-M2 diastasis was the most common abnormal finding, in 46 cases (90.1%). Specificity and positive predictive value were 1.0 in C1-M2 avulsion, diastasis, and C1\u2013intermediate cuneiform (C2) diastasis. Abnormal findings of C1-C2, C1-M1, and C2-M2 showed a significant relationship with intraoperative instability ( P &lt; .05).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>C1-M2 avulsion and diastasis and C1-C2 diastasis were definite preoperative predictors of instability. In unstable subtle Lisfranc injuries, 90% had at least a minor radiographic abnormality at the C1-M2 joint on nonweightbearing radiographs. However, caution should be exercised to identify instability without radiographic abnormality in the C1-M2 joint.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence:<\/jats:title>\n                    <jats:p>Level IV, retrospective case series<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/1071100717717220","type":"journal-article","created":{"date-parts":[[2017,7,20]],"date-time":"2017-07-20T11:29:34Z","timestamp":1500550174000},"page":"1120-1125","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":33,"title":["Nonweightbearing Radiographs in Patients With a Subtle Lisfranc Injury"],"prefix":"10.1177","volume":"38","author":[{"given":"Dong-Kyo","family":"Seo","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, GangNeung Asan Hospital, University of Ulsan, College of Medicine, GangNeung-si, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ho-Seong","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Asan Medical Center, University of Ulsan, College of Medicine, Seoul, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ki Won","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, GangNeung Asan Hospital, University of Ulsan, College of Medicine, GangNeung-si, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suk Kyu","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, GangNeung Asan Hospital, University of Ulsan, College of Medicine, GangNeung-si, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sang-Bum","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, GangNeung Asan Hospital, University of Ulsan, College of Medicine, GangNeung-si, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2017,7,14]]},"reference":[{"key":"bibr1-1071100717717220","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198870020-00003"},{"key":"bibr2-1071100717717220","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.L00413"},{"key":"bibr3-1071100717717220","doi-asserted-by":"publisher","DOI":"10.1177\/107110079801900806"},{"key":"bibr4-1071100717717220","doi-asserted-by":"publisher","DOI":"10.1177\/036354659302100403"},{"key":"bibr5-1071100717717220","doi-asserted-by":"publisher","DOI":"10.1177\/107110070602700819"},{"key":"bibr6-1071100717717220","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-013-2491-2"},{"key":"bibr7-1071100717717220","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.46B4.700"},{"key":"bibr8-1071100717717220","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199072100-00013"},{"key":"bibr9-1071100717717220","doi-asserted-by":"publisher","DOI":"10.1148\/120.1.79"},{"key":"bibr10-1071100717717220","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-200710000-00018"},{"key":"bibr11-1071100717717220","doi-asserted-by":"publisher","DOI":"10.1177\/107110079701800608"},{"key":"bibr12-1071100717717220","doi-asserted-by":"publisher","DOI":"10.1177\/0363546517697297"},{"key":"bibr13-1071100717717220","doi-asserted-by":"publisher","DOI":"10.1177\/036354659402200316"},{"key":"bibr14-1071100717717220","doi-asserted-by":"publisher","DOI":"10.1177\/107110078600600504"},{"key":"bibr15-1071100717717220","doi-asserted-by":"publisher","DOI":"10.1177\/03635465020300061901"},{"key":"bibr16-1071100717717220","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.G.01420"},{"key":"bibr17-1071100717717220","doi-asserted-by":"publisher","DOI":"10.1177\/107110079801900704"},{"key":"bibr18-1071100717717220","doi-asserted-by":"publisher","DOI":"10.3928\/01477447-20110922-23"},{"key":"bibr19-1071100717717220","doi-asserted-by":"publisher","DOI":"10.1097\/00005131-199602000-00008"},{"key":"bibr20-1071100717717220","doi-asserted-by":"publisher","DOI":"10.1016\/j.injury.2004.07.014"},{"issue":"2","key":"bibr21-1071100717717220","first-page":"e1015","volume":"9","author":"Shazadeh Safavi P","year":"2017","journal-title":"Cureus"},{"key":"bibr22-1071100717717220","doi-asserted-by":"publisher","DOI":"10.1016\/j.injury.2006.10.002"},{"key":"bibr23-1071100717717220","doi-asserted-by":"publisher","DOI":"10.1177\/107110078300300508"},{"key":"bibr24-1071100717717220","doi-asserted-by":"publisher","DOI":"10.1016\/S0030-5898(20)31989-1"},{"key":"bibr25-1071100717717220","doi-asserted-by":"publisher","DOI":"10.1080\/02841850600806340"}],"container-title":["Foot &amp;
