Abstract

Pelvic bone metastases frequently result in severe pain and disability. Open surgical reconstruction is associated with a high complication and mortality rate. Percutaneous screw fixation is a minimally invasive treatment that is safe and effective for the management of periacetabular metastases. This article details our technique for pelvic screw fixation, including (1) perioperative care, (2) navigation and needle guidance, (3) access, (4) biopsy and ablation, (5) screw placement, and (6) cement augmentation.

Keywords: ablation; augmentation; fracture; metastases; pelvis; screw.
