Patients and Methods: We retrospectively reviewed 71 consecutive patients who underwent MR imaging of bilateral hips that showed nontraumatic ONFH. There were 110 hips with ONFH and 31 normal hips; one hip received bipolar arthroplasty before the MR studies. All cases of ONFH had typical MR findings. The epiphyseal scars in the femoral head were classified as type I (a sealed-off scar) or type II (a perforated scar). Bone marrow edema, if present, in the proximal femur was identified on coronal T2-weighted or STIR MR images.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n The type of femoral epiphyseal scar was clearly delineated in 97 hips. In cases with ONFH, a type I scar occurred in 46 hips (64%), and a type II scar in 26 hips (36%). In cases of ONFH with bone marrow edema, 69% of hips (24\/35) had a type I scar and 31% of hips (11\/35) had a type II scar. There was no statistical association between the type of epiphyseal scar and ONFH, regardless of staging (P=0.29), or the type of scar and bone marrow edema (P=0.42).<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n There is not a significant statistical association between a sealed-off scar and ONFH.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/112070000901900414","type":"journal-article","created":{"date-parts":[[2018,1,26]],"date-time":"2018-01-26T11:55:29Z","timestamp":1516967729000},"page":"382-385","source":"Crossref","is-referenced-by-count":0,"title":["Is there an Association between Epiphyseal Scar and Osteonecrosis of the Femoral Head?"],"prefix":"10.1177","volume":"19","author":[{"given":"Guo-Shu","family":"Huang","sequence":"first","affiliation":[{"name":"Department of Radiology, Tri-Service General Hospital, National Defense Medical Center, Taipei 114, Taiwan - ROC"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Herng-Sheng","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Pathology, Tri-Service General Hospital, National Defense Medical Center, Taipei 114, Taiwan - ROC"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Min-Szu","family":"Yao","sequence":"additional","affiliation":[{"name":"Department of Radiology, Taipei Medical University\u2013Wan-Fang Hospital, Taipei 116, Taiwan - ROC"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wing P.","family":"Chan","sequence":"additional","affiliation":[{"name":"Department of Radiology, Taipei Medical University\u2013Wan-Fang Hospital, Taipei 116, Taiwan - ROC"},{"name":"Department of Radiology, School of Medicine, Taipei Medical University, Taipei 110, Taiwan - ROC"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2018,1,26]]},"reference":[{"key":"bibr1-112070000901900414","doi-asserted-by":"publisher","DOI":"10.1186\/1749-799X-2-15"},{"key":"bibr2-112070000901900414","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199707000-00012"},{"key":"bibr3-112070000901900414","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.191.2.8153314"},{"key":"bibr4-112070000901900414","doi-asserted-by":"publisher","DOI":"10.1007\/s00256-004-0811-9"},{"key":"bibr5-112070000901900414","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.181.2.1810545"},{"key":"bibr6-112070000901900414","doi-asserted-by":"publisher","DOI":"10.3109\/17453679508994629"},{"key":"bibr7-112070000901900414","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejrad.2007.03.019"},{"key":"bibr8-112070000901900414","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.77B1.7822393"},{"key":"bibr9-112070000901900414","first-page":"11","volume-title":"Ischemia and necrosis of bone.","author":"Ficat R.P.","year":"1980"},{"key":"bibr10-112070000901900414","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.213.3.r99dc06715"},{"key":"bibr11-112070000901900414","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.174.3.1740735"},{"key":"bibr12-112070000901900414","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.171.1.2928517"},{"key":"bibr13-112070000901900414","doi-asserted-by":"publisher","DOI":"10.1007\/s002640050335"}],"container-title":["HIP International"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/112070000901900414","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/112070000901900414","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T08:19:55Z","timestamp":1777450795000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/112070000901900414"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,10]]},"references-count":13,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2009,10]]}},"alternative-id":["10.1177\/112070000901900414"],"URL":"https:\/\/doi.org\/10.1177\/112070000901900414","relation":{},"ISSN":["1120-7000","1724-6067"],"issn-type":[{"value":"1120-7000","type":"print"},{"value":"1724-6067","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,10]]}}}
