摘要： An improved spinal implant includes vertically offset keels for mechanically interlocking respectively with overlying and underlying vertebral bone structures when implanted therebetween. At least one upper keel projects upwardly for close-fit reception into a prepared slot formed in the overlying vertebral structure, and at least one lower keel projects downwardly for similar close-fit reception into a prepared slot formed in the underlying vertebral structure. The upper and lower keels are misaligned or offset from each other to preclude creation of a common stress line extending therethrough, thereby significantly reducing risk of vertebral fracture.

摘要： A spinal implant prosthesis includes a pair of end plates for affixation to adjacent vertebral bone structures and respectively defining inter-engaged convex and concave articulatory surfaces of elliptical profile. These elliptical articulatory surfaces are elongated in an anterior-posterior direction, and are comparatively shorter in a medial-lateral direction. With this configuration, in response to angular displacement and/or axial rotation, the elliptical surfaces displace in a manner increasing the distance between the adjacent vertebral bone structures, thereby tensioning the prosthesis and producing counteracting forces which urge the components back toward a substantially centered or neutral position. In addition, in the preferred form, the anterior-posterior length of the concave articulatory surface in incrementally greater than the anterior-posterior length of the convex articulatory surface to accommodate a limited range of anterior-posterior translation.

摘要： An improved knee prosthesis includes a ceramic tibial component for articulation with natural or prosthetic (re-surfaced) femoral surfaces. The ceramic tibial component is provided in the form of a ceramic monoblock adapted for fixation relative to the patient's tibial bone, or alternately in the form of a ceramic bearing insert component carried by a tibial baseplate member which is adapted in turn for fixation relative to tibial bone. In either form, the ceramic tibial component includes at least one upwardly concave articulation surface for movable bearing engagement by a generally convex or condylar shaped femoral articulation surface. The ceramic tibial component provides improved wear characteristics with extended service life.
