Both hips of 20 young and 20 elderly healthy volunteers were examined. Magnetic resonance imaging was performed at four different positions for each hip: neutral, 45\u00b0 flexion, 15\u00b0 extension, and the Patrick position. Femoral and pelvic bone images were separately extracted when in the neutral position and superimposed over the images of each different position by using voxel\u2010based registration. The distance between the acetabular center and the femoral head center (FHC) at the neutral position was defined as 3D\u2010migration. The distance between FHCs at neutral position and that at each different position was defined as 3D\u2010translation. The x\u2010, y\u2010, and z\u2010axes pointed in the anterior, cranial, and lateral directions, respectively. 3D\u2010migration\u2010y in the elderly was more caudal than that in the young (<jats:italic>P<\/jats:italic>\u2009&lt;\u2009.001). 3D\u2010translation of 45\u00b0 flexion in the elderly was larger than that in the young with statistical significance (<jats:italic>P<\/jats:italic>\u2009=\u2009.001), while 3D\u2010translation of the Patrick position in the elderly was smaller than that in the young (<jats:italic>P<\/jats:italic>\u2009=\u2009.012). Age was significantly correlated with 3D\u2010translation in 45\u00b0 flexion (<jats:italic>r<\/jats:italic>\u2009=\u2009.431; <jats:italic>P<\/jats:italic>\u2009&lt;\u2009.001) and that in Patrick (<jats:italic>r<\/jats:italic>\u2009=\u2009\u2212.296; <jats:italic>P<\/jats:italic>\u2009=\u2009.008). These results can be used as a basis for the natural course with aging of morphometry and kinematics of the hip, as well as for potential disease progression in osteoarthritis of the hip.<\/jats:p>","DOI":"10.1002\/jor.24806","type":"journal-article","created":{"date-parts":[[2020,7,16]],"date-time":"2020-07-16T14:31:51Z","timestamp":1594909911000},"page":"359-369","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Age\u2010related differences in morphology and kinematics of the native hip"],"prefix":"10.1002","volume":"40","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4638-1668","authenticated-orcid":false,"given":"Keisuke","family":"Akiyama","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery Osaka Minami Medical Center  Kawachinagano Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Sakai","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery Yamaguchi University Graduate School of Medicine  Ube Yamaguchi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junichiro","family":"Koyanagi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery Osaka Rosai Hospital  Sakai Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hideki","family":"Yoshikawa","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery Osaka University Graduate School of Medicine  Suita Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuomi","family":"Sugamoto","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Biomaterial Science Osaka University Graduate School of Medicine  Suita Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,7,29]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joca.2009.11.004"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joca.2012.11.012"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joca.2011.01.017"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/jor.22414"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-012-2654-3"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.1917.02590530018010"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1145\/37402.37422"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.D.02885"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.BRS.0000116998.55056.3C"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1145\/146370.146374"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2009.03.033"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/jor.22530"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bone.2019.115037"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/jor.21469"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joca.2017.08.008"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9290(97)00051-1"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1038\/2171290a0"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-198612000-00005"},{"key":"e_1_2_7_20_1","first-page":"103","article-title":"Quantitative morphology of the subchondral plate of the tibial plateau","volume":"185","author":"Milz S","year":"1994","journal-title":"J Anat"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-7580.1998.19210081.x"},{"key":"e_1_2_7_22_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-72019-2_1"},{"key":"e_1_2_7_23_1","doi-asserted-by":"publisher","DOI":"10.1002\/art.27467"},{"key":"e_1_2_7_24_1","doi-asserted-by":"publisher","DOI":"10.1002\/art.20124"},{"key":"e_1_2_7_25_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joca.2003.09.007"},{"key":"e_1_2_7_26_1","doi-asserted-by":"publisher","DOI":"10.1136\/ard.52.8.557"},{"key":"e_1_2_7_27_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joca.2011.12.014"},{"key":"e_1_2_7_28_1","doi-asserted-by":"publisher","DOI":"10.1136\/annrheumdis-2013-203691"},{"key":"e_1_2_7_29_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joca.2014.03.010"},{"key":"e_1_2_7_30_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00276-015-1427-6"},{"key":"e_1_2_7_31_1","doi-asserted-by":"publisher","DOI":"10.1097\/BLO.0b013e31815b181f"},{"key":"e_1_2_7_32_1","doi-asserted-by":"publisher","DOI":"10.1002\/jor.20852"},{"key":"e_1_2_7_33_1","first-page":"643","article-title":"False profile of the pelvis.
