A spinal implant for intervertebral disc replacement. The implant is formed from two hemicylindrical elements, each engaging one of an adjacent pair of vertebrae. An articulating ball-and-socket joint between the two elements resists compression and lateral movement between the vertebra, but allows pivotal movement, thereby preserving mobility. Fusion chambers are provided for allowing bone ingrowth to fuse the elements to the vertebrae. Biocompatible, bioreabsorbable struts, shims, fillers and/or end caps are provided for temporary stabilization of the first and second hemicylindrical elements. Bone chips removed from the vertebrae during implantation or bone growth stimulators can be inserted into the fusion chamber or otherwise applied to the implant to enhance bone ingrowth.
