The complex anatomy of the pelvis renders this procedure challenging. The objective of this study was to assess standardized angles and dimensions of safety zones within a 3\u00a0D computed tomography model for optimal supra-acetabular screw placement.<\/jats:p><jats:p>\n            Methods Computed tomography scans of 107 patients that suffered major trauma without showing any bone injury of the pelvis were collected. Using a software-based analysis, raw computed tomography data were transformed into 3\u00a0D models to set standardized landmarks and determine the possible insertion corridor.<\/jats:p><jats:p>\n            Results Screws not exceeding a length of 97\u00a0mm in females and 106.4\u00a0mm in males were, in 95% of the evaluated cases, insertable without cortical bone penetration. The safety zone was 6.6\u00a0mm for females and 7.9\u00a0mm for males. Screws not exceeding these diameters were safely insertable in 95% of the cases. For the midsagittal plane, the angle was 36.4\u00a0\u00b1\u00a05.1 on the left and 34.7\u00a0\u00b1\u00a02.9 on the right (p\u00a0=\u00a00.008). For the anterior pelvic plane, the angle was 31.3\u00a0\u00b1\u00a04.5\u00b0 on the left and 34.0\u00a0\u00b1\u00a04.8\u00b0 on the right (p\u00a0=\u00a00.008).<\/jats:p><jats:p>\n            Conclusions Percutaneous fixation using supra-acetabular screws is a promising method to treat simple supra-acetabular fractures. These results may improve its safe utilization and could facilitate its broader clinical application.<\/jats:p>","DOI":"10.1055\/a-2107-0948","type":"journal-article","created":{"date-parts":[[2023,7,18]],"date-time":"2023-07-18T22:40:37Z","timestamp":1689720037000},"page":"419-425","source":"Crossref","is-referenced-by-count":4,"title":["Description of Standardized Planes and Angles for Percutaneous Supra-acetabular Screw Placement"],"prefix":"10.1055","volume":"162","author":[{"given":"Julian","family":"R\u00fcwald","sequence":"first","affiliation":[{"name":"Department of Anesthesiology and Intensive Care Medicine, Essen, Germany, University Hospital Essen, Essen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Milena Maria","family":"Ploeger","sequence":"first","affiliation":[{"name":"Department for Orthopaedics and Trauma Surgery, University Hospital Bonn, Bonn, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gunnar T","family":"Hischebeth","sequence":"additional","affiliation":[{"name":"Institute for Medical Microbiology, Immunology and Parasitology, University Hospital Bonn, Bonn, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mareike","family":"T\u00fcllmann","sequence":"additional","affiliation":[{"name":"Department for Orthopaedics and Trauma Surgery, University Hospital Bonn, Bonn, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jonas","family":"Roos","sequence":"additional","affiliation":[{"name":"Department for Orthopaedics and Trauma Surgery, University Hospital Bonn, Bonn, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9368-2033","authenticated-orcid":false,"given":"Martin","family":"Gathen","sequence":"additional","affiliation":[{"name":"Department for Orthopaedics and Trauma Surgery, University Hospital Bonn, Bonn, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1458-2825","authenticated-orcid":false,"given":"Koroush","family":"Kabir","sequence":"additional","affiliation":[{"name":"Department for Orthopaedics and Trauma Surgery, University Hospital Bonn, Bonn, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2023,7,18]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"897","DOI":"10.2106\/00004623-199072060-00016","article-title":"Operative treatment of complex acetabular fractures.
