Abstract

This invention relates to an intervertebral motion disc having two motion surfaces and. wherein the radius of the upper articulation surface of the core member is greater than the radius of the lower articulation surface of the core member, and wherein the first articulation surface of the core member is spherical and the second articulation surface of the core member is curved and non-spherical.

Claims

exact text as granted — not AI-modified
1 . (canceled) 
     
     
         2 . An intervertebral device comprising:
 a component having a first surface and a second surface opposite the first surface, the second surface having teeth configured to mate with a vertebral body; and   a projection that extends out from the first surface in a direction away from the second surface,   wherein the first surface comprises a porous titanium coating, and the projection comprises a material other than the porous titanium coating.   
     
     
         3 . The intervertebral device of  claim 2 , wherein the porous titanium coating has a material property of promoting bony affixation. 
     
     
         4 . The intervertebral device of  claim 3 , wherein the average pore size is 250 microns. 
     
     
         5 . The intervertebral device of  claim 2 , wherein the average pore size is 250 microns. 
     
     
         6 . A system comprising:
 the intervertebral device as recited in  claim 1 ; and   a screw configured to be driven into the vertebral body.   
     
     
         7 . A method comprising the steps of:
 inserting an intervertebral device into an intervertebral disc space, the intervertebral device comprising:
 i) a component having a first surface and a second surface opposite the first surface, the second surface having teeth configured to mate with a vertebral body; and 
 ii) a projection that extends out from the first surface in a direction away from the second surface, 
 wherein the first surface comprises a porous titanium coating, and the projection comprises a material other than the porous titanium coating. 
   
     
     
         8 . The method of  claim 7 , wherein the porous titanium coating has a material property of promoting bony affixation. 
     
     
         9 . The method of  claim 8 , wherein the average pore size is 250 microns. 
     
     
         10 . The method of  claim 7 , wherein the average pore size is 250 microns. 
     
     
         11 . The method of  claim 6 , further comprising the step of driving a screw into the vertebral body.
