Sacral osteoradionecrosis is a pelvic radiation-induced injury. The case illustrates this complication with interventional radiology support. Combination of imaging modalities aided in diagnosis and a biopsy confirmed it. An initial sacral cementoplasty procedure was not sufficient to obtain analgesia, because necrosis continued to evolve. In order to better stabilize the weakened pelvic girdle and reduce pain, percutaneous screw fixation was performed. The patient has a favorable outcome, with reduction of pain and early rehabilitation. No infectious, hemorrhagic complication nor migration of the screws were observed at 6 months’ follow-up. Percutaneous image-guided screwing is a minimally invasive technique allowing stabilization of weakened bone and may be proposed in combination with cementoplasty in patients with sacral osteoradionecrosis.
