An In Vitro Biomechanical Investigation: Variable Positioning of Leopard Carbon Fiber Interbody Cages

Abstract

Positioning of interbody cages in an offset position shows higher strain upon posterior instrumentation than a central position, and quicker load to failure than an anteriorly placed cage. Biomechanical studies using shear loading, and testing of adjacent spinal levels, are necessary to further elucidate the biomechanical consequences of variable positioning of interbody cages.
