US 2010/0076490 A1 · FACET JOINT BROACHING INSTRUMENT, IMPLANT, AND ASSOCIATED METHOD

Abstract

The present disclosure relates to a facet joint broaching instrument, implant, and associated method for stabilizing/immobilizing a facet joint of the spine. The instrument is configured to bore a broaching spike through the facet joint to create a bore in the facet joint. The instrument is further configured to remove excess bone material from the broaching operation through the bore. Once a bore is formed through the facet joint, a facet joint implant is positioned through the bore thereby stabilizing and immobilizing the facet joint. In an exemplary embodiment, the instrument includes a pair of handles, a hinge, opposing arms, a broaching spike, and a receiving chamber for excess bone. The present invention further includes the implant for use with the instrument and an associated surgical method for stabilizing and immobilizing a facet joint with the implant and the instrument.
