Surgeons should use multiple long screws engaging both iliac bones and inserted through the S1 level for optimum fixation. Surgeons can combine this technique with sacroplasty or closed posterior instrumentation to augment screw fixation.
Researchers examined six oncologic patients with sacral insufficiency fractures who underwent additional radiation therapy. The patients were operated on with navigated percutaneous fixation. A total 18 SI screws were placed.
In one case, a screw revision was required due to radiculopathy. There were no reports of hardware failure after at least one year, and there were no cases of perioperative morbidity or mortality. Additionally, patients reported a significant improvement in Karnofsky Performance Status scores and pain levels.
