1. A decorticator apparatus for preparing a joint for receipt of a bone fusion implant, comprising:
a polymer sheath having a lumen therein, a distal end, and a proximal end, the polymer sheath configured to be inserted into a working channel providing access to the joint;
a metal rod disposed within the lumen of the polymer sheath in an immobilized relation thereto, the metal rod having a first end and a second end;
an abrading head disposed on the first end of the metal rod and extending beyond the distal end of the polymer sheath, the abrading head having an abrading surface configured to abrade a cortical bone layer within the joint; and
a longitudinal channel disposed on the polymer sheath and having an opening at the distal end thereof, the longitudinal channel configured to slidingly receive an alignment protrusion of a working channel, whereby engagement between the longitudinal channel and the alignment protrusion restricts axial rotation of the decorticator apparatus relative to the working channel thereby maintaining the abrading head of the decorticator apparatus in a predetermined alignment relative to the joint.
