Patent ID: 8623053

Claim:
A spinal facet fusion implant adapted to be positioned between spaced apart spinal facets that form a facet joint, comprising: an elongated main body having a distal end, a proximal end and a longitudinal, y-axis extending between the distal end and the proximal end, a transverse, x-axis and a z-axis perpendicular to said longitudinal and transverse axes; said elongated main body having longitudinally-extending, transversely opposed sides: at least one semi-circular cavity formed in each spinal facet of a pair of opposed, spaced apart spinal facets; at least one stabilizer extending radially outwardly from said elongated main body in the z-axis; said elongated main body having a width in the transverse axis that is less than the combined width of the spinal facets making up a facet joint; said elongated main body oriented so that said transversely opposed sides are disposed within said semi-circular cavities formed in said opposed, spaced apart spinal facets: said at least one stabilizer having a predetermined width that is sized to make a press fit into a gap between said spinal facets when said elongated main body is oriented with said transversely opposed sides disposed within said opposed semi-circular cavities.
