  • Spinal fusion implant and related methods
    Patent number: 8623088
    Abstract: A spinal fusion implant of non-bone construction to be introduced into any variety of spinal target sites. The spinal fusion implant of the present invention includes a top surface, a bottom surface, first and second lateral sides, a proximal (posterior) end and a distal (anterior) end. The spinal fusion implant of the present invention may be used to provide temporary or permanent fixation within an orthopedic target site. To do so, the spinal fusion implant may be introduced into a disc space while locked to a surgical insertion instrument and thereafter employed in the proper orientation and released. Once deposited in the disc space, the spinal fusion implant of the present invention effects spinal fusion over time as the natural healing process integrates and binds the implant.
