Abstract
Facet fixation implants include a cap member with a circular base portion and an eccentric raised portion. The raised portion includes first and second lobes and is smoothly contoured to provide an unobtrusive profile when implanted. Beveled teeth project from the implant to provide fixation and compression across the facet joint. The cap member includes an offset aperture which receives a fastener. Tools, guiding instruments and methods for implantation of the implants are disclosed.
