Abstract

A posterior lumbar interbody fusion (PLIF) implant that comprises a body with substantially parallel posterior and anterior sidewalls, and a pair of superior and inferior faces. The implant is inserted via an insertion tool within a depression in the sidewalls of the implant. The insertion tool is secured to the side walls of the implant to prevent any bending or breaking of the implant or the inserter during implantation. Once inserted, the implant may be rotated approximately 90 degrees within the disc space. Because of the shape and size of the implant, the effective height of the implant within a patient's disc space is increased upon rotation.
