A spinal facet joint distraction system comprising:
- an assembly comprising:
- a delivery device comprising:
- a first tubular shaft having a proximal end and a distal end and defining a lumen therebetween, the distal end further including a pair of anchoring forks adapted to penetrate the facet joint;
- and
- a receiving assembly on the proximal end of the first tubular shaft, the receiving assembly defining a bore extending therethrough, wherein the bore is positioned proximal to and in alignment with the tubular shaft such that an inner radius of the bore and an inner radius of the tubular shaft match such that there is a smooth transition between the receiving assembly and the tubular shaft;
- and
- a chisel comprising:
- a cylindrical shaft having a proximal end opposite a distal end, the distal end including a tip,
- wherein the assembly is adapted to engage the facet joint.
