Abstract
Disclosed are devices, system and methods for spinal implants to be deployed into an intervertebral space between adjacent vertebrae to replace the function of the intervertebral disc and the facets, while restoring stability, flexibility, coronal alignment/balance, sagittal alignment/balance and proper biomechanical motion.
Claims20
A spinal implant system comprising:
- a superior element having a first superior stop, a second superior stop and a superior articulation surface positioned between the first and second superior stops;
- an inferior element having an inferior base and a bridge portion coupled to a posterior portion of the inferior base, the inferior base including a first inferior stop, a second inferior stop and an inferior articulation component positioned between the first and second inferior stops, the inferior articulation component having an inferior articulation surface which engages with the superior articulation surface to allow articulation of the superior element relative to the inferior element between a first relative position where the first superior stop contacts the first inferior stop and a second relative position where the second superior stop contacts the second inferior stop, the first relative position being different than the second relative position;
- the inferior articulation surface having an inferior articulation surface finish and a first stop surface having a first stop surface finish, wherein the inferior articulation surface finish is a smoother surface finish than the first stop surface finish.
