Biomechanical Evaluation of a Novel Apatite-Wollastonite Ceramic Cage Design for Lumbar Interbody Fusion: A Finite Element Model Study

Figure 2

Following bilateral facetectomy and partial discectomy performed in silico in the L4-L5 motion segment to simulate posterolateral interbody fusion (PLIF), cages and a posterior instrumentation system are implanted.
