Percutaneously placed screws transfixing the sacroiliac joint have become the gold standard for their treatment. However, screw cut\u2010out, backing\u2010out, and loosening are common complications. One promising option could be cerclage reinforcement of cannulated screw fixations. Therefore, the aim of this study was to evaluate the biomechanical feasibility of posterior pelvic ring injuries fixed with S1 and S2 transsacral screws augmented with cerclage.\u00a0Twenty\u2010four\u00a0composite osteoporotic pelvises with posterior sacroiliac joint dislocation were stratified into four groups for S1\u2013S2 transsacral fixation using either (1) fully threaded screws, (2) fully threaded screws with cable cerclage, (3) fully threaded screws with wire cerclage, or (4) partially threaded screws with wire cerclage. All specimens were biomechanically tested under progressively increasing cyclic loading until failure. Intersegmental movements were monitored by motion tracking. The transsacral partially threaded screw fixation with wire cerclage augmentation resulted in significantly less combined angular intersegmental movement in the transverse and coronal plane versus its fully threaded counterpart (<jats:italic>p<\/jats:italic>\u2009=\u20090.032), as well as in significantly less flexion versus all other fixations (<jats:italic>p<\/jats:italic>\u2009\u2264\u20090.029). Additional cerclage augmentation could be performed intraoperatively to improve the stability of posterior pelvic ring injuries treated with S1\u2013S2 transsacral screw fixation. Further investigations should follow to consolidate the current results on real bones and possibly consider execution of a clinical study.<\/jats:p>","DOI":"10.1002\/jor.25634","type":"journal-article","created":{"date-parts":[[2023,5,29]],"date-time":"2023-05-29T07:19:42Z","timestamp":1685344782000},"page":"2740-2748","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Cerclage augmentation of S1\u2013S2 transsacral screw fixation in osteoporotic posterior pelvis ring injuries: A biomechanical feasibility study"],"prefix":"10.1002","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9582-1810","authenticated-orcid":false,"given":"Till","family":"Berk","sequence":"first","affiliation":[{"name":"Biomedical Development AO Research Institute Davos Davos Switzerland"},{"name":"Department of Trauma University Hospital Zurich Zurich Switzerland"},{"name":"Harald\u2010Tscherne Laboratory for Orthopedic and Trauma Research University of Zurich Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0484-887X","authenticated-orcid":false,"given":"Ivan","family":"Zderic","sequence":"additional","affiliation":[{"name":"Biomedical Development AO Research Institute Davos Davos Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8747-6786","authenticated-orcid":false,"given":"Peter","family":"Schwarzenberg","sequence":"additional","affiliation":[{"name":"Biomedical Development AO Research Institute Davos Davos Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sascha","family":"Halvachizadeh","sequence":"additional","affiliation":[{"name":"Department of Trauma University Hospital Zurich Zurich Switzerland"},{"name":"Harald\u2010Tscherne Laboratory for Orthopedic and Trauma Research University of Zurich Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0310-4668","authenticated-orcid":false,"given":"Michel","family":"Teuben","sequence":"additional","affiliation":[{"name":"Department of Trauma University Hospital Zurich Zurich Switzerland"},{"name":"Harald\u2010Tscherne Laboratory for Orthopedic and Trauma Research University of Zurich Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Geoff","family":"Richards","sequence":"additional","affiliation":[{"name":"Biomedical Development AO Research Institute Davos Davos Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9795-115X","authenticated-orcid":false,"given":"Boyko","family":"Gueorguiev","sequence":"additional","affiliation":[{"name":"Biomedical Development AO Research Institute Davos Davos Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hans\u2010Christoph","family":"Pape","sequence":"additional","affiliation":[{"name":"Department of Trauma University Hospital Zurich Zurich Switzerland"},{"name":"Harald\u2010Tscherne Laboratory for Orthopedic and Trauma Research University of Zurich Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,6,11]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.archger.2017.03.007"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00113-011-2020-z"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S8756-3282(01)00614-7"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11657-020-00871-9"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.injury.2013.06.023"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005131-199604000-00005"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.injury.2018.05.027"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0020-1383(16)47002-6"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00402-016-2471-3"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/jor.23401"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.spinee.2015.08.016"},{"key":"e_1_2_10_13_1","doi-asserted-by":"crossref","unstructured":"ChoJ\u2010H.
