Transiliac\u2013transsacral (TITS) screw fixation offers biomechanical advantages for stabilizing unstable posterior pelvic ring injuries, yet clinical outcomes remain underreported. We aim to report radiographic and clinical outcomes of TITS fixation for posterior pelvic ring injuries in FFP. (2) Methods: We conducted a retrospective review of 22 elderly female patients (mean age 79.0 \u00b1 7.9 years) who underwent TITS screw fixation for unstable posterior pelvic ring fragility fractures between 2019 and 2024. Perioperative, radiographic, and functional outcomes were analyzed. (3) Results: Median operative time was 74 min (IQR 55\u201390 min), with minimal blood loss (median 5 mL). No intraoperative neurovascular injuries occurred. Median hospital stay was 7 days (IQR 5\u201310 days). At a mean follow-up of 6 months, 81.8% of patients maintained excellent or good reduction. Screw loosening was observed in 18.2% of cases, with only one (4.5%) requiring revision. Median VAS scores (range 0\u201310) decreased significantly from 5 preoperatively to 2 at discharge (p &lt; 0.001). By discharge, 59.1% of patients were able to ambulate with assistance. (4) Conclusion: TITS screw fixation is a safe and feasible option for stabilizing unstable FFP in elderly, osteoporotic patients. It provides reliable mechanical stability, promotes early mobilization, and is associated with a short hospital stay and low complication rates.<\/jats:p>","DOI":"10.3390\/life16010102","type":"journal-article","created":{"date-parts":[[2026,1,12]],"date-time":"2026-01-12T07:30:34Z","timestamp":1768203034000},"page":"102","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Transiliac\u2013Transsacral Screw Provides Good Outcomes for Stabilizing Unstable Fragility Fracture of the Pelvis: A Retrospective Case Series"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-7108-609X","authenticated-orcid":false,"given":"Ping-Ying","family":"Yu","sequence":"first","affiliation":[{"name":"Department of Orthopedics, Kaohsiung Veterans General Hospital, Kaohsiung City 813, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8124-4354","authenticated-orcid":false,"given":"Kai-Cheng","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Kaohsiung Veterans General Hospital, Kaohsiung City 813, Taiwan"},{"name":"Department of Occupational Therapy, Shu-Zen Junior College of Medicine and Management, Kaohsiung City 821, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yih-Wen","family":"Tarng","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Kaohsiung Veterans General Hospital, Kaohsiung City 813, Taiwan"},{"name":"Department of Medical Education and Research, Kaohsiung Veterans General Hospital, Kaohsiung City 813, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chien-Jen","family":"Hsu","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Kaohsiung Veterans General Hospital, Kaohsiung City 813, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1733","DOI":"10.1016\/j.injury.2013.06.023","article-title":"Comprehensive classification of fragility fractures of the pelvic ring: Recommendations for surgical treatment","volume":"44","author":"Rommens","year":"2013","journal-title":"Injury"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"378","DOI":"10.1097\/BOT.0b013e3181e47fad","article-title":"Transiliac-transsacral screws for posterior pelvic stabilization","volume":"25","author":"Gardner","year":"2011","journal-title":"J.
