The study aimed to investigate the course of the lumbosacral trunk with reference to SIJ and determine whether is there sufficient space for two screws through the sacrum while performing anterior plating. Sixty patients, who underwent an MRI of the lumbar spine were included in our study. The three transverse LT\u2014SIJ distances were measured at the three points (A, B, and C). We also analyzed 60 CT pelvic scans at points A, B, and C in order to measure: the vertebral canal\u2013to\u2013SIJ distance, the sacrum\u2019s pelvic\u2013to\u2013dorsal surface sagittal distance, and the median plane\u2013to\u2013SIJ angle. The mean transverse LT\u2013SIJ distances at points A, B, and C were 20.0 \u00b1 3.05 mm, 17.9 \u00b1 3.20 mm, and 12.3 \u00b1 2.49 mm, respectively. Based on CT analyses, the vertebral canal\u2013to\u2013SIJ distances were 30.5 \u00b1 7.65 mm at point A, 21.4 \u00b1 5.05 mm at point B and 15.7 \u00b1 6.05 mm at point C. The sacrum\u2019s pelvic\u2013to\u2013dorsal surface sagittal distances reached values: 35.1 \u00b1 11.62 mm at point A, 52.5 \u00b1 10.58 mm at point B, and 57.5 \u00b1 7.79 mm at point C. The median plane\u2013to\u2013SIJ angles measured 31.4 \u00b1 4.82 degrees at point A, 26.6 \u00b1 3.77 degrees at point B and 21.3 \u00b1 3.25 mm at point C. Proximally, the safe zone for applying an anterior plate of SIJ is 20.0 mm. Since both the safe zone and safe corridor taper distally, surgeons may securely use one screw of gradually increased length towards the distal direction of SIJ, with inclination of 30 degrees in relation to the median plane of the lesser pelvis.<\/jats:p>","DOI":"10.1371\/journal.pone.0292620","type":"journal-article","created":{"date-parts":[[2023,10,19]],"date-time":"2023-10-19T17:29:46Z","timestamp":1697736586000},"page":"e0292620","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":7,"title":["Anatomy of the sacroiliac joint with relation to the lumbosacral trunk: Is there sufficient space for a two-hole plate?"],"prefix":"10.1371","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1979-849X","authenticated-orcid":true,"given":"Micha\u0142","family":"Ku\u0142akowski","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karol","family":"Elster","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pawe\u0142","family":"Reichert","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6283-5500","authenticated-orcid":true,"given":"Aleksandra","family":"Kr\u00f3likowska","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joanna","family":"Jerominko","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pawe\u0142","family":"\u015al\u0119czka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Magdalena","family":"Grzonkowska","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Micha\u0142","family":"Szpinda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mariusz","family":"Baumgart","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2023,10,19]]},"reference":[{"issue":"8","key":"pone.0292620.ref001","doi-asserted-by":"crossref","first-page":"691","DOI":"10.1016\/j.injury.2006.04.130","article-title":"Epidemiology of adult fractures: A review","volume":"37","author":"CM Court-Brown","year":"2006","journal-title":"Injury"},{"issue":"3","key":"pone.0292620.ref002","doi-asserted-by":"crossref","first-page":"297","DOI":"10.3109\/17453679209154786","article-title":"Epidemiology of pelvic fractures in a Swedish county","volume":"63","author":"B Ragnarsson","year":"1992","journal-title":"Acta Orthopaedica Scandinavica"},{"issue":"6","key":"pone.0292620.ref003","first-page":"1850","article-title":"Eastern Association for the Surgery of Trauma practice management guidelines for hemorrhage in pelvic fracture\u2014update and systematic review","volume":"71","author":"DC Cullinane","year":"2011","journal-title":"J Trauma"},{"issue":"8","key":"pone.0292620.ref004","doi-asserted-by":"crossref","first-page":"869","DOI":"10.1016\/j.injury.2008.03.024","article-title":"Closed reduction and iliosacral percutaneous fixation of unstable pelvic ring fractures","volume":"39","author":"D Schweitzer","year":"2008","journal-title":"Injury"},{"issue":"3","key":"pone.0292620.ref005","doi-asserted-by":"crossref","first-page":"143","DOI":"10.5435\/00124635-199605000-00004","article-title":"Acute Pelvic Fractures: I.
