A spinal joint distraction system comprising: a) a delivery device including a tubular shaft; and, b) a chisel including a shaft with a chamfered tip, the chisel being adapted for slidable insertion through the delivery device, wherein the delivery device further comprises: a receiving assembly (110; 111) positioned on a proximal end of the tubular shaft and including a seating cavity; and, a pair of forks extending from a distal end of the tubular shaft, the forks adapted to penetrate a facet joint; and wherein the system further comprises: c) a decorticator sleevably positioned on or in the tubular shaft of the delivery device, the decorticator comprising: a tubular shaft portion with a chamfered distal end; and, a handle positioned on the proximal end of the tubular shaft portion, d) a driver assembly adapted for slidable insertion through the delivery device, the driver assembly comprising: an implant shaft; a handle positioned on the proximal end of the implant shaft; implant holding arms extending from the distal end of the implant shaft; an internal actuator adapted for slidable insertion through the shaft of the driver assembly and further adapted to advance an implant distractor, the internal actuator comprising: a longitudinal shaft; and a handle positioned on the proximal end of the longitudinal shaft and adapted to rotatably advance the implant distractor. a) a delivery device including a tubular shaft; and, b) a chisel including a shaft with a chamfered tip, the chisel being adapted for slidable insertion through the delivery device, wherein the delivery device further comprises: a receiving assembly (110;
