In order to determine the reproducibility of the methods, 50 hips were evaluated by two skilled examiners. In an inter-observer study, five physicians and five medical students evaluated 24 images, which were evaluated on ten occasions at two-weekly intervals by one of the authors. Statistical evaluation used the Bland-Altman approach. <\/jats:p><jats:p> The neonates (110 females, 122 males) were less than four days old. The mean \u03b1 angle was 62.4\u00b0 and mean femoral head cover was 55.4%. According to Graf\u2019s method, 1.3% of hips were pathological, compared with 4.1% according to Terjesen. Spearman\u2019s correlation coefficient between femoral head cover and \u03b1 angles was 0.552. The Bland-Altman approach shows greater variation for femoral head cover than for \u03b1, if measured by experienced examiners. The Bland-Altman approach shows almost equal reproducibility for \u03b1 and femoral head cover in the inter-observer test, but better repeatability for \u03b1 in the intra-observer test. <\/jats:p><jats:p> The Graf results relate better than Terjesen\u2019s to the well-known frequency of 1% to 2% hip dysplasia in the European population. Kappa statistics indicate a fair agreement between the two methods. Inter-observer evaluation shows an equal reproducibility of both methods, whereas intra-observer tests reveal better repeatability with Graf\u2019s method. <\/jats:p>","DOI":"10.1302\/0301-620x.88b1.16419","type":"journal-article","created":{"date-parts":[[2005,12,19]],"date-time":"2005-12-19T17:28:34Z","timestamp":1135013314000},"page":"104-106","source":"Crossref","is-referenced-by-count":33,"title":["Comparing ultrasound measurements of neonatal hips using the methods of Graf and Terjesen"],"prefix":"10.1302","volume":"88-B","author":[{"given":"A.","family":"Falliner","sequence":"first","affiliation":[{"name":"Clinic of Orthopaedic Surgery"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.","family":"Schwinzer","sequence":"additional","affiliation":[{"name":"Clinic of Orthopaedic Surgery"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.-J.","family":"Hahne","sequence":"additional","affiliation":[{"name":"Clinic of Orthopaedic Surgery"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Hedderich","sequence":"additional","affiliation":[{"name":"Institut for Medical Informatics and Statistics, University Hospital Schleswig-Holstein, Campus Kiel, D-24105 Kiel, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Hassenpflug","sequence":"additional","affiliation":[{"name":"Institut for Medical Informatics and Statistics, University Hospital Schleswig-Holstein, Campus Kiel, D-24105 Kiel, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"42","reference":[{"key":"R1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00450934"},{"key":"R2","doi-asserted-by":"publisher","DOI":"10.7863\/jum.1984.3.3.131"},{"key":"R3","doi-asserted-by":"publisher","DOI":"10.3109\/17453678909149596"},{"key":"R4","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.71B5.2684989"},{"key":"R5","doi-asserted-by":"crossref","unstructured":"Falliner A, Hahne HJ, Hassenpflug J.
