Reconstruction of Noncontained Distal Femoral Defects with Polymethylmethacrylate and Crossed-Screw Augmentation: A Biomechanical Study

Abstract

In this in vitro cadaver study, augmentation of polymethylmethacrylate cement with crossed screws resulted in a stronger reconstruction of distal femoral tumor defects than that obtained with cement alone or with cement and intramedullary Steinmann pins.
