On lateral foot-ankle weight-bearing radiographs, the tibiocalcaneal angle, plantigrade angle, and McDermott grade were measured and the presence of anterior blocking spur was evaluated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Eleven patients (40.7%) had anterior ankle impingement on radiographic findings preoperatively and 24 patients (88.9%) at latest follow-up. There was a significant difference in McDermott grade between preoperative and latest follow-up ( P &lt; .001). There were significant differences in tibiocalcaneal angle and plantigrade angle between the patients with anterior ankle pain and without anterior ankle pain ( P = .006 and .011, respectively) and between the patients with anterior blocking spur and without anterior blocking spur ( P = .005 and .010, respectively).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Most patients with residual poliomyelitis had anterior ankle impingement after tendo-Achilles lengthening for long-standing equinus deformity, and the presence of symptomatic anterior ankle impingement was significantly associated with the severity of the equinus deformity. Therefore, for residual poliomyelitis patients with severe long-standing equinus deformity, surgeons should consider the possibility of a subsequent anterior procedure for anterior impingement after tendo-Achilles lengthening.<\/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\/1071100713488092","type":"journal-article","created":{"date-parts":[[2013,4,25]],"date-time":"2013-04-25T23:53:58Z","timestamp":1366934038000},"page":"1233-1237","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Anterior Ankle Impingement After Tendo-Achilles Lengthening for Long-Standing Equinus Deformity in Residual Poliomyelitis"],"prefix":"10.1177","volume":"34","author":[{"given":"Ki Hyuk","family":"Sung","sequence":"first","affiliation":[{"name":"Kwandong University Myongji Hospital, Kyungki, Goyang, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chin Youb","family":"Chung","sequence":"additional","affiliation":[{"name":"Seoul National University Bundang Hospital, Kyungki, Sungnam, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyoung Min","family":"Lee","sequence":"additional","affiliation":[{"name":"Seoul National University Bundang Hospital, Kyungki, Sungnam, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seung Yeol","family":"Lee","sequence":"additional","affiliation":[{"name":"Seoul National University Bundang Hospital, Kyungki, Sungnam, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Moon Seok","family":"Park","sequence":"additional","affiliation":[{"name":"Seoul National University Bundang Hospital, Kyungki, Sungnam, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2013,4,25]]},"reference":[{"key":"bibr1-1071100713488092","doi-asserted-by":"publisher","DOI":"10.1177\/107110070102200407"},{"key":"bibr2-1071100713488092","doi-asserted-by":"publisher","DOI":"10.1002\/sim.1108"},{"key":"bibr3-1071100713488092","doi-asserted-by":"publisher","DOI":"10.1055\/s-2007-984418"},{"key":"bibr4-1071100713488092","doi-asserted-by":"publisher","DOI":"10.1097\/01.bpo.0000173244.74065.e4"},{"issue":"2","key":"bibr5-1071100713488092","doi-asserted-by":"crossref","first-page":"327","DOI":"10.1016\/S1083-7515(24)00140-2","volume":"5","author":"Dhillon MS","year":"2000","journal-title":"Foot Ankle Clin"},{"key":"bibr6-1071100713488092","doi-asserted-by":"publisher","DOI":"10.1177\/107110070502600312"},{"key":"bibr7-1071100713488092","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.09.2427"},{"key":"bibr8-1071100713488092","doi-asserted-by":"publisher","DOI":"10.1177\/1938640011412944"},{"key":"bibr9-1071100713488092","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2006.03.013"},{"key":"bibr10-1071100713488092","doi-asserted-by":"publisher","DOI":"10.1007\/s11751-011-0111-6"},{"key":"bibr11-1071100713488092","doi-asserted-by":"publisher","DOI":"10.1016\/j.rehab.2009.10.002"},{"key":"bibr12-1071100713488092","doi-asserted-by":"publisher","DOI":"10.1016\/j.fcl.2006.06.003"},{"key":"bibr13-1071100713488092","doi-asserted-by":"publisher","DOI":"10.1177\/107110079201300303"},{"key":"bibr14-1071100713488092","doi-asserted-by":"publisher","DOI":"10.1016\/j.fcl.2006.02.002"},{"key":"bibr15-1071100713488092","doi-asserted-by":"publisher","DOI":"10.1007\/s12178-012-9117-z"}],"container-title":["Foot &amp; Ankle International"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1071100713488092","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1071100713488092","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1071100713488092","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T21:23:20Z","timestamp":1777411400000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1071100713488092"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,4,25]]},"references-count":15,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2013,9]]}},"alternative-id":["10.1177\/1071100713488092"],"URL":"https:\/\/doi.org\/10.1177\/1071100713488092","relation":{},"ISSN":["1071-1007","1944-7876"],"issn-type":[{"value":"1071-1007","type":"print"},{"value":"1944-7876","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,4,25]]}}}
