Here, we studied the change in the cross-sectional area (CSA) of the osseous lumbar spinal canal measured in subjects from three ethnic groups born 70 years apart and established reference values for our local population. This retrospective study included a total of 1050 subjects born between 1930 and 1999 stratified by birth decade. All subjects underwent lumbar spine computed tomography (CT) as a standardized imaging procedure following trauma. Three independent observers measured the CSA of the osseous lumbar spinal canal at the L2 and L4 pedicle levels. Lumbar spine CSA was smaller at both L2 and L4 in subjects born in later generations (p &lt; 0.001; p = 0.001). This difference reached significance for patients born three to five decades apart. This was also true within two of the three ethnic subgroups. Patient height was very weakly correlated with the CSA at both L2 and L4 (r = 0.109, p = 0.005; r = 0.116, p = 0.002). The interobserver reliability of the measurements was good. This study confirms the decrease of osseous lumbar spinal canal dimensions across decades in our local population.<\/jats:p>","DOI":"10.3390\/diagnostics13040734","type":"journal-article","created":{"date-parts":[[2023,2,15]],"date-time":"2023-02-15T03:37:24Z","timestamp":1676432244000},"page":"734","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Evolution of the Cross-Sectional Area of the Osseous Lumbar Spinal Canal across Decades: A CT Study with Reference Ranges in a Swiss Population"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1910-6038","authenticated-orcid":false,"given":"Benoit","family":"Maeder","sequence":"first","affiliation":[{"name":"Spine Center, Lausanne University Hospital and University of Lausanne, 1011 Lausanne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8444-8504","authenticated-orcid":false,"given":"Fabio","family":"Becce","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Interventional Radiology, Lausanne University Hospital and University of Lausanne, 1011 Lausanne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sam","family":"Kehtari","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Traumatology, Lausanne University Hospital and University of Lausanne, 1011 Lausanne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arnaud","family":"Monier","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Interventional Radiology, Lausanne University Hospital and University of Lausanne, 1011 Lausanne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Etienne","family":"Chaboudez","sequence":"additional","affiliation":[{"name":"Faculty of Biology and Medicine, University of Lausanne, 1011 Lausanne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dominique A.","family":"Rothenfluh","sequence":"additional","affiliation":[{"name":"Spine Center, Lausanne University Hospital and University of Lausanne, 1011 Lausanne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Constantin","family":"Schizas","sequence":"additional","affiliation":[{"name":"Neuro-Orthopaedic Spine Unit, Clinic Cecil, 1003 Lausanne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Steven D.","family":"Hajdu","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Interventional Radiology, Lausanne University Hospital and University of Lausanne, 1011 Lausanne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"n1581","DOI":"10.1136\/bmj.n1581","article-title":"Lumbar spinal stenosis","volume":"373","author":"Jensen","year":"2021","journal-title":"BMJ"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2143","DOI":"10.1007\/s00586-020-06339-1","article-title":"Prevalence of lumbar spinal stenosis in general and clinical populations: A systematic review and meta-analysis","volume":"29","author":"Jensen","year":"2020","journal-title":"Eur.
