P96 - Outcomes and Cost-Minimization Analysis of Cement Spacers and Expandable Cages for Posterior-Only Reconstruction of Metastatic Spine Corpectomies

Abstract

BACKGROUND CONTEXT: Reconstruction of the thoracic/lumbar spine after tumor corpectomy for metastatic spine disease (MSD) can be achieved using either an expandable metallic cage (EC) or a polymethylmethacrylate (PMMA) cement spacer, through a posterior-only approach. Few studies have compared the relative successes between these two techniques of reconstruction in the management of metastatic spine disease. We hypothesized that the rate of complications and revision surgery when using PMMA spacers to reconstruct the spine after corpectomy for MSD would be equivalent to use of an EC, with lower implant and operating room (OR) costs for PMMA.
