An Unconstrained Force-Control Testing Protocol for Evaluating Endplate Conforming Interbody Cage Designs

Description

The presentation focuses on the mechanical characterization of patient-specific implants, specifically lumbar interbody cages designed with gyroid and Voronoi lattice structures. The speaker discusses the challenges of current preclinical test standards for these implants and proposes a new testing methodology to evaluate implant subsidence more effectively. This involves using a custom testing setup to assess the compressive properties of these implants when subjected to axial loads, while closely monitoring their rotation and performance. The findings indicate that anatomical cages may require more force to reach specific subsidence levels, revealing differences in behavior compared to traditional designs. The presentation concludes with the need for further validation through in vitro cadaveric studies.
