In this retrospective analysis of traditional Chinese medicine, non-traumatic ONFH (NONFH) patients from January 2008 to December 2013 were selected. The patients were divided into collapse group and non-collapse group based on whether the femoral head collapsed. The anatomical parameters including center\u2013edge (CE) angle, sharp angle, acetabular depth ratio and MSR were evaluated. Receiver operating characteristic curves were estimated to evaluate the sensitivity and specificity of MSR and CE angle in collapse prediction. The results showed that 135 patients (151 hips) were included in this study. The differences in CE angle and MSR between collapse group and non-collapse group were statistically significant. The mean survival time of the hips of patients with MSR &amp;lt;20.35 was greater (P\u2009&amp;lt;\u20090.001) than that of patients with MSR &amp;gt;20.35. The ONFH patients with MSR &amp;gt;20.35 were prone to stress concentration. We could conclude that the hip joint MSR and CE angle strongly correlated with the collapse of NONFH. The specificity of MSR is higher than that of CE angle. When MSR is &amp;gt;20.35, the collapse rate of ONFH will increase significantly.<\/jats:p>","DOI":"10.1093\/jhps\/hnab049","type":"journal-article","created":{"date-parts":[[2021,6,22]],"date-time":"2021-06-22T10:14:52Z","timestamp":1624356892000},"page":"311-317","source":"Crossref","is-referenced-by-count":4,"title":["Relationship between hip joint medial space ratio and collapse of femoral head in non-traumatic osteonecrosis: a retrospective study"],"prefix":"10.1093","volume":"8","author":[{"given":"Tianye","family":"Lin","sequence":"first","affiliation":[{"name":"Department of Joint Orthopaedic, The Third Affiliated Hospital, Guangzhou University of Chinese Medicine, 261 Longxi Avenue, Liwan, Guangzhou, Guangdong 510405, China"},{"name":"Institute of Orthopedics, Guangzhou University of Chinese Medicine, 261 Longxi Avenue, Liwan, Guangzhou, Guangdong 510405, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keda","family":"Li","sequence":"additional","affiliation":[{"name":"Liaoning University of Chinese Medicine, No. 79, Chongshan East Road, Huanggu, Shengyang, Liaoning 110033, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weijian","family":"Chen","sequence":"additional","affiliation":[{"name":"Guangzhou Orthopedic Hospital, Guangzhou University of Chinese Medicine, 449 Dongfeng Middle Road, Yuexiu, Guangzhou, Guangdong 510405, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peng","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Joint Orthopaedic, The Third Affiliated Hospital, Guangzhou University of Chinese Medicine, 261 Longxi Avenue, Liwan, Guangzhou, Guangdong 510405, China"},{"name":"Institute of Orthopedics, Guangzhou University of Chinese Medicine, 261 Longxi Avenue, Liwan, Guangzhou, Guangdong 510405, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhikun","family":"Zhuang","sequence":"additional","affiliation":[{"name":"Quanzhou Osteopathic Hospital Affiliated to Fujian University of Traditional Chinese Medicine, No. 61, South Section of Citong West Road, Quanzhou, Fujian 362000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Zhang","sequence":"additional","affiliation":[{"name":"Luoyang Orthopedic-Traumatological Hospital, 82 Qiming South Road, Luoyang, Henan 471000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"He","sequence":"additional","affiliation":[{"name":"Department of Joint Orthopaedic, The Third Affiliated Hospital, Guangzhou University of Chinese Medicine, 261 Longxi Avenue, Liwan, Guangzhou, Guangdong 510405, China"},{"name":"Institute of Orthopedics, Guangzhou University of Chinese Medicine, 261 Longxi Avenue, Liwan, Guangzhou, Guangdong 510405, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qingwen","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Joint Orthopaedic, The Third Affiliated Hospital, Guangzhou University of Chinese Medicine, 261 Longxi Avenue, Liwan, Guangzhou, Guangdong 510405, China"},{"name":"Institute of Orthopedics, Guangzhou University of Chinese Medicine, 261 Longxi Avenue, Liwan, Guangzhou, Guangdong 510405, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiushi","family":"Wei","sequence":"additional","affiliation":[{"name":"Department of Joint Orthopaedic, The Third Affiliated Hospital, Guangzhou University of Chinese Medicine, 261 Longxi Avenue, Liwan, Guangzhou, Guangdong 510405, China"},{"name":"Institute of Orthopedics, Guangzhou University of Chinese Medicine, 261 Longxi Avenue, Liwan, Guangzhou, Guangdong 510405, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2021,6,22]]},"reference":[{"key":"2022042911184284600_R1","doi-asserted-by":"crossref","first-page":"1604","DOI":"10.2106\/JBJS.O.00071","article-title":"Nontraumatic osteonecrosis of the femoral head: where do we stand today?
