Three well\u2010defined imaging planes were chosen to evaluate navicular displacement: the medial malleolus\u2010navicular (MM\u2010N) distance, soft tissue thickness, talar deformity and the calcaneo\u2010cuboid (C\u2010C) distance. Intra\u2010 and interobserver agreement was analysed using Cohen's kappa for the discrete variables and by Bland\u2010Altman's graphic technique for measurements.<\/jats:p>\n                  <jats:p>Results: Kappa values for intra\u2010observer agreement were 0.82 for navicular displacement, 0.93 for \u201ctalar head pointing laterally\u201d, and 0.70 for medial deviation of the talar neck. The corresponding interobserver kappa values were 0.70, 0.68, and 0.36. The mean difference between the two observers for the MM\u2010N distance was 0.42\u00b13.0\u2009mm and for the soft tissue thickness 0.35\u00b12.0\u2009mm; the C\u2010C distance showed a mean interobserver distance of 0.0\u00b12.8\u2009mm.<\/jats:p>\n                  <jats:p>Conclusion: The imaging planes used to study the talo\u2010navicular and calcaneo\u2010cuboid relationships are reproducible and relatively easy to learn. Intra\u2010 and interobserver assessments were acceptable for MM\u2010N distance, soft tissue thickness, navicular displacement and \u201ctalar head pointing laterally\u201d, but questionable for the C\u2010C distance and medial deviation of the talar neck.<\/jats:p>","DOI":"10.1080\/02841850410008360","type":"journal-article","created":{"date-parts":[[2004,10,6]],"date-time":"2004-10-06T10:49:15Z","timestamp":1097059755000},"page":"622-627","source":"Crossref","is-referenced-by-count":21,"title":["Repeatability of sonographic measurements in clubfeet"],"prefix":"10.1177","volume":"45","author":[{"given":"Y.","family":"Aurell","sequence":"first","affiliation":[{"name":"Department of Diagnostic Radiology, Halmstad Central Hospital, Halmstad, Sweden; Department of Diagnostic Radiology and Department of Orthopaedics, Lund University Hospital, Lund, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Adlercreutz","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, Halmstad Central Hospital, Halmstad, Sweden; Department of Diagnostic Radiology and Department of Orthopaedics, Lund University Hospital, Lund, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"Andriesse","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, Halmstad Central Hospital, Halmstad, Sweden; Department of Diagnostic Radiology and Department of Orthopaedics, Lund University Hospital, Lund, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Jonsson","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, Halmstad Central Hospital, Halmstad, Sweden; Department of Diagnostic Radiology and Department of Orthopaedics, Lund University Hospital, Lund, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2016,8,30]]},"container-title":["Acta Radiologica"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1080\/02841850410008360","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1080\/02841850410008360","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T13:46:27Z","timestamp":1777383987000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.sagepub.com\/doi\/10.1080\/02841850410008360"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004,10]]},"references-count":0,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2004,10]]}},"alternative-id":["10.1080\/02841850410008360"],"URL":"https:\/\/doi.org\/10.1080\/02841850410008360","relation":{},"ISSN":["0284-1851","1600-0455"],"issn-type":[{"value":"0284-1851","type":"print"},{"value":"1600-0455","type":"electronic"}],"subject":[],"published":{"date-parts":[[2004,10]]}}}
