Three hundred and fifty patients with LSTV (52.3 \u00b1 10.9 years), including 182 Castellvi type I, 107 type II, 43 type III, and 18 type IV, and 179 controls without LSTV (50.6 \u00b1 13.1 years), were studied. Discs, endplates, and posterior vertebral structures were assessed and compared to those of controls for the most caudal three discs on MRIs. There were no differences in degenerative findings between patients with type I LSTV and controls. For types III and IV, the transitional discs had smaller sizes, lower Pfirrmann scores, and lower rates of disc bulging (2.3% and 5.6% vs. 39.1%), osteophytes (2.3% vs. 15.1%), disc herniation (2.3% and 5.6% vs. 31.8%), and Modic changes (2.3% and 5.6% vs. 16.8%) than controls. However, the cranial discs had more severe Pfirrmann scores, disc narrowing and spinal canal narrowing, and greater rates of disc herniation (41.9% and 50.0% vs. 25.7%), endplate defects (27.9% and 33.3% vs. 14.4%) and spondylolisthesis (18.6% vs. 7.3%) than controls. Type II LSTV was associated with degenerative findings in the cranial segments but to a lesser degree, as compared with type III\/IV LSTV. Thus, Castellvi type III\/IV LSTV predisposed the adjacent spinal components to degeneration and protected the transitional discs. Type II LSTV had significant effects in promoting transitional and adjacent disc degeneration. Type I LSTV was not related to spinal degeneration.<\/jats:p>","DOI":"10.3390\/jcm11092339","type":"journal-article","created":{"date-parts":[[2022,4,23]],"date-time":"2022-04-23T08:14:06Z","timestamp":1650701646000},"page":"2339","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Lumbosacral Transitional Vertebra Contributed to Lumbar Spine Degeneration: An MR Study of Clinical Patients"],"prefix":"10.3390","volume":"11","author":[{"given":"Linxiang","family":"Cheng","sequence":"first","affiliation":[{"name":"Spine Lab, Department of Orthopedic Surgery, The First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou 310003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao","family":"Jiang","sequence":"additional","affiliation":[{"name":"Spine Lab, Department of Orthopedic Surgery, The First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou 310003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiawei","family":"Huang","sequence":"additional","affiliation":[{"name":"Spine Lab, Department of Orthopedic Surgery, The First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou 310003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiale","family":"Jin","sequence":"additional","affiliation":[{"name":"Spine Lab, Department of Orthopedic Surgery, The First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou 310003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5626-0790","authenticated-orcid":false,"given":"Ming","family":"Guan","sequence":"additional","affiliation":[{"name":"Spine Lab, Department of Orthopedic Surgery, The First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou 310003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6580-809X","authenticated-orcid":false,"given":"Yue","family":"Wang","sequence":"additional","affiliation":[{"name":"Spine Lab, Department of Orthopedic Surgery, The First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou 310003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"610","DOI":"10.1016\/j.spinee.2010.04.012","article-title":"Complete sacralization of L5 vertebrae: Traits, dimensions, and load bearing in the involved sacra","volume":"10","author":"Mahato","year":"2010","journal-title":"Spine J."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"910","DOI":"10.1016\/j.spinee.2010.07.392","article-title":"Morphological traits in sacra associated with complete and partial lumbarization of first sacral segment","volume":"10","author":"Mahato","year":"2010","journal-title":"Spine J."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"858","DOI":"10.1016\/j.spinee.2011.08.005","article-title":"The prevalence of transitional vertebrae in the lumbar spine","volume":"11","author":"Apazidis","year":"2011","journal-title":"Spine J."},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"497","DOI":"10.1148\/radiol.12112747","article-title":"Lumbosacral Transitional Vertebrae: Association with Low Back Pain","volume":"265","author":"Nardo","year":"2012","journal-title":"Radiology"},{"key":"ref_5","doi-asserted-by":"crossref","first-page":"1679","DOI":"10.1016\/j.ejrad.2014.05.036","article-title":"Lumbosacral transitional vertebra in a population-based study of 5860 individuals: Prevalence and relationship to low back pain","volume":"83","author":"Tang","year":"2014","journal-title":"Eur.
