The pathoanatomical features of Charcot neuropathy have been evaluated in only a few studies. This study evaluated whether medial navicular subluxation (adduction of the navicular on the talus) is a radiographic finding present in patients with Charcot neuroarthropathy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>A retrospective review of 143 consecutive patients diagnosed with Charcot arthropathy of the foot from January 2004 to May 2011 was performed. Patients were identified based on a clinical diagnosis code 713.5 during an outpatient clinic visit with 2 surgeons at a single institution. After exclusion criteria were applied, a series of radiographs of 50 feet in 40 patients were compared with radiographs from an age-matched control group. Radiographic data including talonavicular coverage angle and talonavicular uncoverage percentage were collected.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The mean talonavicular coverage angle of the Charcot arthropathy group was 1.5 degrees and of the control group 12.1 degrees ( P &lt; .05). The talonavicular uncoverage value for the Charcot arthropathy group was 12.2% and for the control group 22.0% ( P &lt; .001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Medial navicular subluxation was a radiographic finding that was more commonly present in patients with Charcot arthropathy than in a matched control group. It is theorized that this finding is attributable to an unopposed pull of the posterior tibial tendon on the destabilized navicular.<\/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\/1071100713491729","type":"journal-article","created":{"date-parts":[[2013,6,5]],"date-time":"2013-06-05T02:16:46Z","timestamp":1370398606000},"page":"1548-1551","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Navicular Subluxation as a Radiographic Finding in Charcot Neuroarthropathy"],"prefix":"10.1177","volume":"34","author":[{"given":"Allyson","family":"Estess","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, University of Southern California, Los Angeles, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicole","family":"Marquand","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, University of Southern California, Los Angeles, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Timothy P.","family":"Charlton","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, University of Southern California, Los Angeles, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David B.","family":"Thordarson","sequence":"additional","affiliation":[{"name":"Cedars-Sinai Medical Center, Los Angeles, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2013,6,4]]},"reference":[{"key":"bibr1-1071100713491729","first-page":"895","volume-title":"Surgery of the Foot and Ankle","volume":"1999","author":"Brodsky JW"},{"key":"bibr2-1071100713491729","doi-asserted-by":"publisher","DOI":"10.5435\/00124635-200807000-00005"},{"key":"bibr3-1071100713491729","volume-title":"Charcot Joints","author":"Eichenholtz S","year":"1966"},{"key":"bibr4-1071100713491729","doi-asserted-by":"publisher","DOI":"10.3113\/FAI.2009.1168"},{"key":"bibr5-1071100713491729","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-196749010-00001"},{"key":"bibr6-1071100713491729","doi-asserted-by":"publisher","DOI":"10.1177\/107110079501601108"},{"key":"bibr7-1071100713491729","doi-asserted-by":"publisher","DOI":"10.1177\/107110079301400305"},{"key":"bibr8-1071100713491729","doi-asserted-by":"publisher","DOI":"10.1177\/107110079801900610"},{"key":"bibr9-1071100713491729","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199804000-00015"},{"key":"bibr10-1071100713491729","doi-asserted-by":"publisher","DOI":"10.1177\/107110070202300106"},{"key":"bibr11-1071100713491729","doi-asserted-by":"publisher","DOI":"10.5435\/00124635-200909000-00003"},{"key":"bibr12-1071100713491729","doi-asserted-by":"publisher","DOI":"10.1177\/107110070502601006"}],"container-title":["Foot &amp; Ankle International"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1071100713491729","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1071100713491729","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1071100713491729","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T21:23:24Z","timestamp":1777411404000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1071100713491729"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,6,4]]},"references-count":12,"journal-issue":{"issue":"11","published-print":{"date-parts":[[2013,11]]}},"alternative-id":["10.1177\/1071100713491729"],"URL":"https:\/\/doi.org\/10.1177\/1071100713491729","relation":{},"ISSN":["1071-1007","1944-7876"],"issn-type":[{"value":"1071-1007","type":"print"},{"value":"1944-7876","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,6,4]]}}}
