An implant for use with the opposing facets of two adjacent vertebrae includes a facet bearing body having a cavity for receiving a filler material, and at least one fixation wing for securing the facet bearing body to at least one of the two vertebrae, wherein the facet bearing body is positionable between the opposing facets and the at least one fixation wing is fixable to at least one of the two vertebrae. The filler material may be an in situ curable polymer such as bone cement, a polyurethane or an elastomer. To stabilize the adjacent vertebrae, the facet bearing body is inserted between the opposing facets of the adjacent vertebrae. The at least one fixation wing is fixed to at least one of the two adjacent vertebrae. The filler material is injected into the cavity and allowed to harden.
