Generating computational models supplemented with muscle forces is a complicated task, especially in the initial phase of implant development. This research aims to expand the possibilities of the simpler acetabular cage model based on joint loads without significantly increasing the demand for computing resources. A Python script covered and grouped the loads from daily activities. The ten calculated major loads were compared with the maximum of the walking and stair climbing loads through the finite element analyses of a custom-made acetabular cage. Sensitivity analyses were performed for the surrounding bones\u2019 elastic modulus and the pelvis boundary conditions. The major loads can geometrically cover the entire load spectrum of daily activities. The effect of many high-magnitude force vectors is uncertain in the approach that uses the most common maximum loads. Using these resultant major loads, a new stress concentration area could be detected on the acetabular cage, besides the stress concentration areas induced by the loads reported\u00a0in the literature. The qualitative correctness of the results is also supported by a control computed tomography scan: a fracture occurred in an extensive, high-stress zone. The results are not sensitive to changes in the elastic modulus of the surrounding bone and the boundary conditions of the model. The presented load vectors and the algorithm make more extensive static analyses possible with little computational overhead. The proposed method can be used for checking the static strength of similar implants.<\/jats:p>","DOI":"10.1007\/s10237-023-01728-z","type":"journal-article","created":{"date-parts":[[2023,6,2]],"date-time":"2023-06-02T08:31:08Z","timestamp":1685694668000},"page":"1411-1423","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Extended mechanical loads for the analysis of acetabular cages"],"prefix":"10.1007","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9708-3559","authenticated-orcid":false,"given":"Martin O.","family":"D\u00f3czi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0856-1772","authenticated-orcid":false,"given":"R\u00f3bert","family":"Sz\u0151dy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5431-1782","authenticated-orcid":false,"given":"P\u00e9ter T.","family":"Zwierczyk","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2023,6,2]]},"reference":[{"issue":"2","key":"1728_CR1","doi-asserted-by":"publisher","first-page":"S238","DOI":"10.1016\/j.jor.2015.10.011","volume":"12","author":"A Ahmad","year":"2015","unstructured":"Ahmad A, Schwarzkopf R (2015) Clinical evaluation and surgical options in acetabular reconstruction: a literature review.
