For both methods, the intra- and interobserver variability of center-edge and acetabular index angle assessment were analyzed. The observers\u2019 ability to diagnose hip dysplasia and osteoarthritis were assessed. All measures were compared to those made on computed tomography scan.<\/jats:p>\n                  <jats:p>Results: Intra- and interobserver variability of angle assessment was less when angles were drawn compared with assessment by vision, and the observers\u2019 ability to diagnose hip dysplasia improved when angles were drawn. Assessment of osteoarthritis in general showed poor agreement with findings on computed tomography scan.<\/jats:p>\n                  <jats:p>Conclusion: We recommend that angles always should be drawn for assessment of hip dysplasia on pelvic radiographs. Given the inherent variability of diagnostic assessment of hip dysplasia, a computed tomography scan could be considered in patients with relevant hip symptoms and a center-edge angle between 20\u00b0 and 30\u00b0. Osteoarthritis should be assessed by measuring the joint space width or by classifying the T\u00f6nnis grade as either 0\u20131 or 2\u20133.<\/jats:p>","DOI":"10.3109\/02841850903447086","type":"journal-article","created":{"date-parts":[[2010,2,10]],"date-time":"2010-02-10T07:44:57Z","timestamp":1265787897000},"page":"187-193","source":"Crossref","is-referenced-by-count":36,"title":["Assessment of hip dysplasia and osteoarthritis: Variability of different methods"],"prefix":"10.1177","volume":"51","author":[{"given":"Anders","family":"Troelsen","sequence":"first","affiliation":[{"name":"Orthopedic Research Unit, University Hospital of Aarhus, Aarhus, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lone","family":"R\u00f8mer","sequence":"additional","affiliation":[{"name":"Department of Radiology, University Hospital of Aarhus, Aarhus, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00f8ren","family":"Kring","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Aabenraa Hospital, Aabenraa, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian","family":"Elmengaard","sequence":"additional","affiliation":[{"name":"Orthopedic Research Unit, University Hospital of Aarhus, Aarhus, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kjeld","family":"S\u00f8balle","sequence":"additional","affiliation":[{"name":"Orthopedic Research Unit, University Hospital of Aarhus, Aarhus, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2010,3,1]]},"container-title":["Acta Radiologica"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.3109\/02841850903447086","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.3109\/02841850903447086","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T13:57:26Z","timestamp":1777384646000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.sagepub.com\/doi\/10.3109\/02841850903447086"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,3]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2010,3]]}},"alternative-id":["10.3109\/02841850903447086"],"URL":"https:\/\/doi.org\/10.3109\/02841850903447086","relation":{},"ISSN":["0284-1851","1600-0455"],"issn-type":[{"value":"0284-1851","type":"print"},{"value":"1600-0455","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,3]]}}}
