Based on 91 specimen locations per cadaver (five cadavers, average age: 77.3 years), we developed detailed methods for specimen preparation and mechanical testing (bending, tensile, and compression) with defined boundary conditions. Multiple measurements were taken to assess repeatability. The proposed methods allow us to identify location-specific properties of the lumbopelvic system for the first time. Cortical bone exhibited an elastic modulus of 1750 MPa and an ultimate strength of 28.2 MPa, while those of trabecular bone were 32.7 MPa and 1.26 MPa, and soft tissues revealed values of 148 MPa and 14.3 MPa for fascial tissue and 103 MPa with 10.7 MPa for ligamentous tissue, respectively. The quantified properties for cortical and trabecular bone and soft tissues not only enhance the comparability of material properties but also support more accurate numerical simulations and implant design. Furthermore, the ease of implementation and standardization of these methods enable their widespread application, as well as the accumulation of a broad database and the setting of benchmarks for future investigations.<\/jats:p>","DOI":"10.3390\/bioengineering12080862","type":"journal-article","created":{"date-parts":[[2025,8,11]],"date-time":"2025-08-11T14:32:36Z","timestamp":1754922756000},"page":"862","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Approach to Standardized Material Characterization of the Human Lumbopelvic System: Testing and Evaluation"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8378-3108","authenticated-orcid":false,"given":"Marc","family":"Gebhardt","sequence":"first","affiliation":[{"name":"Institute of Experimental Mechanics, Faculty of Civil Engineering, Leipzig University of Applied Sciences, 04277 Leipzig, Germany"},{"name":"Institute of Anatomy, Faculty of Medicine, Leipzig University, 04103 Leipzig, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0797-2246","authenticated-orcid":false,"given":"Sascha","family":"Kurz","sequence":"additional","affiliation":[{"name":"ZESBO (Zentrum zur Erforschung der St\u00fctz- und Bewegungsorgane)\u2014Center for Research on Musculoskeletal Systems, Faculty of Medicine, Leipzig University, 04103 Leipzig, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fanny","family":"Grundmann","sequence":"additional","affiliation":[{"name":"Clinic of Trauma, Orthopedic and Septic Surgery, Hospital St. Georg gGmbH, 04129 Leipzig, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Klink","sequence":"additional","affiliation":[{"name":"Institute of Experimental Mechanics, Faculty of Civil Engineering, Leipzig University of Applied Sciences, 04277 Leipzig, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8379-7809","authenticated-orcid":false,"given":"Volker","family":"Slowik","sequence":"additional","affiliation":[{"name":"Institute of Experimental Mechanics, Faculty of Civil Engineering, Leipzig University of Applied Sciences, 04277 Leipzig, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christoph-Eckhard","family":"Heyde","sequence":"additional","affiliation":[{"name":"ZESBO (Zentrum zur Erforschung der St\u00fctz- und Bewegungsorgane)\u2014Center for Research on Musculoskeletal Systems, Faculty of Medicine, Leipzig University, 04103 Leipzig, Germany"},{"name":"Department of Orthopaedic, Trauma and Plastic Surgery, University of Leipzig Medical Center, 04103 Leipzig, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7117-9330","authenticated-orcid":false,"given":"Hanno","family":"Steinke","sequence":"additional","affiliation":[{"name":"Institute of Anatomy, Faculty of Medicine, Leipzig University, 04103 Leipzig, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"537","DOI":"10.1111\/j.1469-7580.2012.01564.x","article-title":"The sacroiliac joint: An overview of its anatomy, function and potential clinical implications","volume":"221","author":"Vleeming","year":"2012","journal-title":"J.
