We report on the prevalence of radiological features associated with hip dysplasia in a population of 2081\u00a019-year-old Norwegians. The radiological measurements used to define hip dysplasia were Wiberg\u2019s centre-edge (CE) angle at thresholds of &lt; 20\u00b0 and &lt; 25\u00b0, femoral head extrusion index &lt; \u00a075%, Sharp\u2019s angle &gt; 45\u00b0, an acetabular depth to width ratio &lt; 250 and the sourcil shape assessed subjectively. The whole cohort underwent clinical examination of their range of hip movement, body mass index (BMI), and Beighton hypermobility score, and were asked to complete the EuroQol (EQ-5D) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). The prevalence of hip dysplasia in the cohort varied from 1.7% to 20% depending on the radiological marker used. A Wiberg\u2019s CE angle &lt; \u00a020\u00b0 was seen in 3.3% of the cohort: 4.3% in women and 2.4% in men. We found no association between subjects with multiple radiological signs indicative of dysplasia and BMI, Beighton score, EQ-5D or WOMAC. Although there appears to be a high prevalence of hip dysplasia among 19-year-old Norwegians, this is dependent on the radiological parameters applied. <\/jats:p><jats:p> Cite this article: Bone Joint J 2013;95-B:279\u201385. <\/jats:p>","DOI":"10.1302\/0301-620x.95b2.30744","type":"journal-article","created":{"date-parts":[[2013,1,30]],"date-time":"2013-01-30T17:18:30Z","timestamp":1359566310000},"page":"279-285","update-policy":"https:\/\/doi.org\/10.1302\/crossmark-policy","source":"Crossref","is-referenced-by-count":65,"title":["Prevalence of radiographic findings associated with hip dysplasia in a population-based cohort of 2081 19-year-old Norwegians"],"prefix":"10.1302","volume":"95-B","author":[{"given":"I. \u00d8.","family":"Enges\u00e6ter","sequence":"first","affiliation":[{"name":"Haukeland University Hospital, Department\rof Orthopaedic Surgery, Jonas Lies vei 65, 5021\rBergen, Norway."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.
