PERCUTANEOUS ARTHRODESIS METHOD AND SYSTEM

摘要

A method and system for percutaneous fusion to correct disc compression is presented. The method has several steps, for instance, inserting a percutaneous lumbar interbody implant; positioning guide wires for each facet screw to be implanted; performing facet arthrodesis in preparation for the facet screws; fixating the plurality of facet screws; and optionally performing foramen nerve root or central decompression. The system includes an implant, an elongate cannulated insertion tool, and an elongate lockshaft positioned within the insertion tool.

主权项

1. A percutaneous fusion method to correct disc compression in a patient, comprising:
making a posterolateral incision to access a desired spinal motion segment; determining a target level of a disc space between adjacent vertebral bodies for implantation of a spinal implant; locating a path to the disc space at the target level; inserting a guide wire to maintain the path to the disc space; selecting an appropriately sized graft implant; placing a spinal implant over the guide wire; sliding the spinal implant along the guide wire to position the spinal implant into the disc space at a desired position; removing the guide wire; and fixating at least a portion of the desired spinal motion segment.
