Predictive value of intraosseous venography before percutaneous vertebroplasty.

Purpose: Percutaneous vertebroplasty is a novel approach for treating patients with painful vertebral body compression fractures. The use of intraosseous venography before the percutaneous injection of polymethylmethacrylate (PMMA) is not universally accepted. The purpose of this study was to determine if intraosseous venography predicts PMMA flow characteristics when injected into a vertebral body.
