Their mean age was 1.62 weeks (95% confidence interval (CI) 1.35 to 1.89). Clinical neonatal hip screening revealed a sensitivity of 62% (mean, 62.6 95%CI 50.9 to 74.3), specificity of 99.8% (mean, 99.8, 95% CI 99.7 to 99.8) and positive predictive value (PPV) of 24% (mean, 26.2, 95% CI 19.3 to 33.0). Static and dynamic sonography for Graf type IV dysplastic hips had a 15-year sensitivity of 77% (mean, 75.8 95% CI 66.9 to 84.6), specificity of 99.8% (mean, 99.8, 95% CI 99.8 to 99.8) and a PPV of 49% (mean, 55.1, 95% CI 41.6 to 68.5). There were 36 infants with an irreducible dislocation of the hip (0.57 per 1000 live births), including six that failed to resolve with neonatal splintage. <\/jats:p><jats:p> Most clinically unstable hips referred to a specialist clinic are female and stabilise spontaneously. Most irreducible dislocations are not identified from this neonatal instability group. There may be a small subgroup of females with instability of the hip which may be at risk of progression to irreducibility despite early treatment in a Pavlik harness. <\/jats:p><jats:p> A controlled study is required to assess the value of neonatal clinical screening programmes. <\/jats:p><jats:p> Cite this article: Bone Joint J 2015;97-B:265-9. <\/jats:p>","DOI":"10.1302\/0301-620x.97b2.34858","type":"journal-article","created":{"date-parts":[[2015,1,27]],"date-time":"2015-01-27T15:12:29Z","timestamp":1422371549000},"page":"265-269","update-policy":"https:\/\/doi.org\/10.1302\/crossmark-policy","source":"Crossref","is-referenced-by-count":33,"title":["Neonatal clinical screening of the hip in the diagnosis of developmental dysplasia of the hip"],"prefix":"10.1302","volume":"97-B","author":[{"given":"J.","family":"Mace","sequence":"first","affiliation":[{"name":"Royal Blackburn Hospital, Haslingden\rRoad, Blackburn, Lancashire\rBB2 3HH, UK."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.
