Patients were categorized into two groups based on disc height (DH) subsidence: cage non-subsidence group (&lt; 2 mm) and cage subsidence group (&gt; 2 mm). General and imaging data were collected pre-surgery, post-surgery, and at six months follow-up. Single-factor analysis identified factors influencing cage subsidence, followed by multi-factor regression analysis on these variables to determine their impact.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>When the degree of DH subsidence in the last follow-up (M6) was evaluated, among the 86 patients (102 segments), 26 patients (25.49%) fulfilled the criteria for cage subsidence. Factors with clinical and statistical significance in the single-factor analysis were incorporated into the multi-factor analysis, and it was found that the mean CT value of the concerned segment, multifidus area, and severe multifidus atrophy were relevant risk factors for cage subsidence; the protective factors for cage subsidence were degree III zygapophyseal joint degeneration, posterior cage position, and end-plate inflammation sclerosis (P\u2009&lt;\u20090.05).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Surgeons should be cautious in preoperatively identifying patients at risk of cage subsidence, particularly those with a low mean CT value of the concerned segment or severe multifidus atrophy. During surgery, selecting a cage of adequate length to span the epiphyseal ring and align with the original DH can help protect paravertebral muscles from iatrogenic injury and reduce the risk of cage subsidence.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/10538127241301673","type":"journal-article","created":{"date-parts":[[2025,1,28]],"date-time":"2025-01-28T23:25:23Z","timestamp":1738106723000},"page":"383-393","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Analysis of factors impacting inter-body fusion cage subsidence following an oblique lateral interbody fusion (OLIF) stand-alone procedure"],"prefix":"10.1177","volume":"38","author":[{"given":"Sheng","family":"Chang","sequence":"first","affiliation":[{"name":"Department of Spine Surgery, The Affiliated Hospital of Qingdao University, Qingdao, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hong-Fei","family":"Xiang","sequence":"additional","affiliation":[{"name":"Department of Spine Surgery, The Affiliated Hospital of Qingdao University, Qingdao, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jia-Hao","family":"Wei","sequence":"additional","affiliation":[{"name":"Department of Spine Surgery, The Affiliated Hospital of Qingdao University, Qingdao, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Spine Surgery, The Affiliated Hospital of Qingdao University, Qingdao, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,1,26]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.3171\/2014.4.SPINE14257"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-199703150-00023"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0000000000003557"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1177\/2192568219864341"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000012680"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0b013e3181a2ea0a"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-020-06667-2"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.wneu.2020.02.047"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-004-0817-y"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1097\/BSD.0b013e318237b9b1"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.J.00160"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1155\/2018\/6853720"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00256-008-0590-9"},{"key":"e_1_3_3_15_2","doi-asserted-by":"publisher","DOI":"10.1007\/s002560050503"},{"key":"e_1_3_3_16_2","doi-asserted-by":"publisher","DOI":"10.1053\/crad.1999.0340"},{"key":"e_1_3_3_17_2","doi-asserted-by":"publisher","DOI":"10.1177\/21925682211067210"},{"key":"e_1_3_3_18_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-009-1036-3"},{"key":"e_1_3_3_19_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13018-018-0740-2"},{"key":"e_1_3_3_20_2","doi-asserted-by":"publisher","DOI":"10.3171\/2013.4.SPINE12319"},{"key":"e_1_3_3_21_2","doi-asserted-by":"publisher","DOI":"10.3171\/2020.5.FOCUS20169"},{"key":"e_1_3_3_22_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.spinee.2022.01.018"},{"key":"e_1_3_3_23_2","first-page":"1449","article-title":"CT Value of vertebral body predicting cage subsidence after stand-alone oblique lumbar interbody fusion","volume":"35","author":"Zhou J","year":"2021","unstructured":"Zhou J, Zhou L, Liu C, et al.
