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

Figure 7

The L5 end plate stress distribution was similar to that of the intact model for flexion, extension, and rotation. The maximum L5 end plate stress value (29.3 MPa) was observed in the K4 model during bending.
