1. A method for delivering an implant to a spinal facet joint via a posterior access approach, the method comprising:
- accessing a spinal joint via a posterior approach;
advancing a chisel toward the spinal facet joint via the posterior approach;
inserting the chisel into the spinal facet joint to provide initial distraction of the joint;
inserting a guide device over the chisel to maintain the initial distraction;
