Results of computed tomography were examined for 52 hip joints with DDH and 73 normal healthy hip joints. DDH shows larger maximum extension (p = 0.001) and internal rotation at 90\u00b0 flexion (p &lt; 0.001). Similar maximum flexion (p = 0.835) and external rotation (p = 0.713) were observed between groups, while high rates of extra-articular impingement were noticed in these directions in DDH (p &lt; 0.001). Smaller cranial acetabular anteversion (p\u00a0=\u00a00.048), centre-edge angles (p &lt; 0.001), a circumferentially shallower acetabulum, larger femoral neck anteversion (p &lt; 0.001), and larger alpha angle were identified in DDH. Risk of anterior impingement in retroverted DDH hips is similar to that in retroverted normal hips in excessive adduction but minimal in less adduction. These findings might be borne in mind when considering the possibility of extra-articular posterior impingement in DDH being a source of pain, particularly for patients with a highly anteverted femoral neck.<\/jats:p><jats:p>Cite this article: Bone Joint J 2014;96-B:580\u20139.<\/jats:p>","DOI":"10.1302\/0301-620x.96b5.32503","type":"journal-article","created":{"date-parts":[[2014,5,1]],"date-time":"2014-05-01T15:08:48Z","timestamp":1398956928000},"page":"580-589","update-policy":"https:\/\/doi.org\/10.1302\/crossmark-policy","source":"Crossref","is-referenced-by-count":49,"title":["Three-dimensional morphology and bony range of movement in hip joints in patients with hip dysplasia"],"prefix":"10.1302","volume":"96-B","author":[{"given":"I.","family":"Nakahara","sequence":"first","affiliation":[{"name":"Osaka National Hospital, Department of Orthopaedic Surgery, 2-1-14 Hoenzaka Chuo-ku, Osaka, 540-0006, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Takao","sequence":"additional","affiliation":[{"name":"Osaka University Graduate School of Medicine, Department of Orthopaedic Surgery, 2-2, Yamadaoka, Suita, 565-0871, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Sakai","sequence":"additional","affiliation":[{"name":"Osaka University Graduate School of Medicine, Department of Orthopaedic Surgery, 2-2, Yamadaoka, Suita, 565-0871, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.","family":"Miki","sequence":"additional","affiliation":[{"name":"Osaka National Hospital, Department of Orthopaedic Surgery, 2-1-14 Hoenzaka Chuo-ku, Osaka, 540-0006, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Nishii","sequence":"additional","affiliation":[{"name":"Osaka University Graduate School of Medicine, Department of Orthopaedic Medical Engineering, 2-2, Yamadaoka, Suita, 565-0871, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.","family":"Sugano","sequence":"additional","affiliation":[{"name":"Osaka University Graduate School of Medicine, Department of Orthopaedic Medical Engineering, 2-2, Yamadaoka, Suita, 565-0871, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"42","reference":[{"key":"r1","doi-asserted-by":"publisher","DOI":"10.1007\/BF01356824"},{"key":"r2","first-page":"29","volume":"83","author":"Wiberg G","year":"1939","journal-title":"Acta Chir Scand Suppl"},{"key":"r3","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.90B11.20073"},{"key":"r4","doi-asserted-by":"crossref","first-page":"214","DOI":"10.1097\/00003086-199012000-00023","volume":"261","author":"Murphy SB","year":"1990","journal-title":"Clin Orthop Relat Res"},{"key":"r5","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.80B4.0800711"},{"key":"r6","doi-asserted-by":"publisher","DOI":"10.1002\/jor.20747"},{"key":"r7","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199507000-00002"},{"key":"r8","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.87B7.15203"},{"key":"r9","doi-asserted-by":"crossref","first-page":"112","DOI":"10.1097\/01.blo.0000096804.78689.c2","volume":"417","author":"Ganz R","year":"2003","journal-title":"Clin Orthop Relat Res"},{"key":"r10","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.93B10.26714"},{"key":"r11","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.13.10692"},{"key":"r12","doi-asserted-by":"publisher","DOI":"10.1007\/s12178-011-9073-z"},{"key":"r13","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.06.0921"},{"key":"r14","doi-asserted-by":"publisher","DOI":"10.1002\/jor.20380"},{"key":"r15","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.84B4.0840556"},{"key":"r16","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.I.00046"},{"key":"r17","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-013-2895-9"},{"key":"r18","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-200401000-00012"},{"key":"r19","doi-asserted-by":"crossref","first-page":"117","DOI":"10.1097\/BLO.0b013e318031c595","volume":"458","author":"Kubiak-Langer M","year":"2007","journal-title":"Clin Orthop Relat Res"},{"key":"r20","doi-asserted-by":"publisher","DOI":"10.1002\/jor.20309"},{"key":"r21","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-012-2344-1"},{"key":"r22","doi-asserted-by":"publisher","DOI":"10.1002\/jor.21265"},{"key":"r23","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-197961010-00004"},{"key":"r24","first-page":"39","volume":"119","author":"T\u00f6nnis D","year":"1976","journal-title":"Clin Orthop Relat Res"},{"key":"r25","doi-asserted-by":"publisher","DOI":"10.1145\/37402.37422"},{"key":"r26","unstructured":"Schroeder W, Martin K, Lorensen WThe Visualization Toolkit: An Object Orient Approach to Computer Graphics.Second ed.
