A prosthetic implant for replacing a facet joint of a spinal motion segment (100) includes a generally conical superior component (200) adapted to be implanted at a surgically prepared site on a lower articular process (118) of a cephalad vertebra of a spinal motion (100), and a cup-shaped inferior component (300) adapted to be implanted at a surgically prepared site on a superior articular process (114) of a caudal vertebra of the spinal motion segment (100). |
