Abstract
The present disclosure relates to a spinal implant or spacer that addresses the variation in anatomy of vertebrae along the spine by having inferior and superior surface angle and convexity variations that are adapted to address the differences in lordosis and endplate surface convexity of the spine. The difference between the convexity of the superior and inferior surface of the spacer increases as the lordotic angle of the spacer increases. The spacers described herein thus provide overall improved fit into vertebral disc space and in some embodiments are even used in the absence of fusion for a prolonged period. The vertebral spacers described herein in some embodiments are used with supplemental internal fixation systems, such as an anchor plate. The interior of the spacer has channels and undercuts to increase graft volume and retention, support bony ingrowth, and bony stability for better secondary and tertiary stabilization.
