The Biomechanics of 1, 2, and 3 Levels of Vertebral Augmentation With Polymethylmethacrylate in Multilevel Spinal Segments

Abstract

Multilevel segment biomechanics are dependent on BMD and not the pattern of augmentation, so the augmentation of fractured vertebrae can be extended to adjacent levels at risk for fracture to maintain stiffness and strength, thus preventing further fractures.
