This study aims to analyze the biomechanical characteristics of tile B2 pelvic fractures using finite element analysis when the superior ramus of the pubis was fixed by a plate or hollow screws in standing and sitting positions, respectively. Methods: A three-dimensional digital model of the tile B2 pelvic fracture was obtained by CT scanning the patient. The main ligament structure was then reconstructed based on the anatomical characteristics to create a finite element model of the tile B2 pelvic fracture. The posterior pelvic ring was fixed by sacroiliac joint screws, while the anterior ring injury of the superior ramus of the pubis was fixed by plates and hollow compression screws, respectively. The degrees of freedom of the bilateral acetabulum or two sides of the ischial tuberosity were constrained in the two models. A vertical load of 600 N was applied to the upper surface of the sacrum to measure the displacement and stress distribution of the pelvis in the standing and sitting positions. Results: The displacement distribution of both the healthy and the affected side of the pelvis was relatively uniform in both the plate group and the hollow screw group according to the finite element simulation results. The maximum displacement value in the sitting position was greater than the standing position, and the maximum displacement value of the hollow screw fixation was greater than that of the plate fixation. In the four groups of fixation models, the maximum displacement value of the pelvis in the hollow screw sitting position group was 1616.80 \u00d7 10\u22123 mm, which was greater than that of the other three groups, and in this group the total displacement value of the hollow screw in the anterior ring was 556.31 \u00d7 10\u22123 mm. The stress distribution of the pelvis in the various models was similar in the four groups of models, in which the maximum stress of the pelvis in the hollow screw sitting position group was the largest, which was 201.33 MPa, while the maximum stress in the standing position was 149.85 MPa greater than that in the sitting position of the hollow screw fixation. Conclusion: The anterior ring of patients with Tile B2 pelvic fractures fixed with hollow screws or plates in both standing and sitting positions can achieve satisfactory biomechanical results with significant safety margins for plates and screws.<\/jats:p>","DOI":"10.3390\/jpm13030506","type":"journal-article","created":{"date-parts":[[2023,3,13]],"date-time":"2023-03-13T04:35:41Z","timestamp":1678682141000},"page":"506","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Finite Element Analysis of Channel Screw and Conventional Plate Technique in Tile B2 Pelvic Fracture"],"prefix":"10.3390","volume":"13","author":[{"given":"Dejian","family":"Li","sequence":"first","affiliation":[{"name":"Department of Orthopedics, Shanghai Pudong Hospital, Fudan University Pudong Medical Center, Shanghai 201300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanru","family":"Ren","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Shanghai Pudong Hospital, Fudan University Pudong Medical Center, Shanghai 201300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Shanghai Pudong Hospital, Fudan University Pudong Medical Center, Shanghai 201300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rongguang","family":"Ao","sequence":"additional","affiliation":[{"name":"Department of Trauma Orthopaedics, Shanghai East Hospital, Tongji University School of Medicine, Shanghai 201300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chengqing","family":"Yi","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Shanghai Pudong Hospital, Fudan University Pudong Medical Center, Shanghai 201300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Baoqing","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Shanghai Pudong New Area People\u2019s Hospital, Shanghai 201202, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"862","DOI":"10.1097\/TA.0000000000003398","article-title":"Demographic changes in pelvic fracture patterns at a Swiss academic trauma center from 2007 to 2017","volume":"92","author":"Villiger","year":"2022","journal-title":"J.
