摘要：
Systems and methods for joint preparation and fusion are disclosed. The system includes a cutting device having a handle, and rigid blade member. The blade member may include cutting edges on first and second sides, and may be curved in one or more planes. The blade member may be deployed to project outside of an outer tube, and the cutting device may be rotated to create a circular cavity. In a method of use, a cannula provides access to a procedure site such as a joint. A pathway to the joint is created, and the cutting device is inserted and deployed to undercut a cavity in the joint. A fusion device may be implanted across the joint to provide compression and fuse the joint. The system may also include instrumentation for creating access to a joint, bone graft insertion and implant insertion.
