Abstract:
A novel allograft is provided for insertion into a prepared site between adjacent spinal facets. The allograft or facet dowel is typically comprised of three portions, a partially spherical body defining a spherical segment, a nose portion, and a tail portion, all aligned along a longitudinal axis. In addition, a set of instruments is provided for the excavation of an allograft placement site between the two facets. The set of instruments includes a T-spade drill which will, in conjunction with a normal drill, excavate a site for the emplacement of the allograft. A novel method of using the instruments and the allograft is also provided.
