摘要：A spinal implant (10) for intervertebral disc replacement. The implant is formedfrom two hemicylindrical elements (20, 22), each engaging one of an adjacent pair ofvertebrae (12, 14). An articulating ball-and-socket joint and/or rocker and channelbetween the two elements resists compression and lateral movement between thevertebra, but allows pivotal movement, thereby preserving mobility. Fusion chambers (30,34) are provided for allowing bone ingrowth to fuse the elements to the vertebrae.Biocompatible, bioreabsorbab le struts, shims (82), fillers and/or end caps (90) areprovided for temporary stabilization of the first (20) and second (22) hemicylindricalelements. Bone chips removed from the vertebrae during implantation or bone growthstimulators can be inserted into the fusion chamber or otherwise applied to the implantto enhance bone ingrowth.
