Surg."],"abstract":"<jats:p>External hemipelvectomy is a radical procedure traditionally reserved for advanced malignancy, with its use in trauma being exceedingly rare. We report a 15-year-old female with severe pelvic trauma complicated by a missed external iliac artery occlusion following internal iliac artery embolization, resulting in irreversible limb ischemia and progressive soft-tissue necrosis. Despite fasciotomy, above-knee amputation, and repeated debridement, the infection advanced proximally with recurrent sepsis, ultimately necessitating a life-saving external hemipelvectomy. Reconstruction was achieved using a deep inferior epigastric artery perforator flap, followed by staged wound management and rehabilitation, leading to complete wound healing. At 28 months of follow-up, the patient was able to ambulate independently with a customized hemipelvic prosthesis. This case highlights a critical diagnostic pitfall in pelvic trauma and demonstrates that timely recognition, multidisciplinary management, and advanced reconstructive strategies can achieve meaningful functional recovery even after radical limb-sacrificing procedures.<\/jats:p>","DOI":"10.3389\/fsurg.2026.1878507","type":"journal-article","created":{"date-parts":[[2026,7,24]],"date-time":"2026-07-24T05:36:14Z","timestamp":1784871374000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Case
