Definitions
- the present invention relates to an intervertebral implant ("T-PLIF implant”) and its use during a transforaminal lumbar interbody fusion procedure.
- T-PLIF implant intervertebral implant
- the T- PLEF implant preferably has at least two vertical through-channels extending through the implant from the superior face to the inferior face, each vertical through-channel having a width and walls on posterior and anterior sides of the width.
- the arcuate implant configuration and the chamfer on the inferior and superior faces at the narrow insertion end of the implant facilitate insertion of the implant via the transforaminal window.
- the implant also has at least two anterior-posterior horizontal through-
- the implant may also feature two or more vertical through-channel(s) extending through the implant from the superior face to the inferior face, each vertical through-channel having a width and walls on posterior and anterior side,s of the width, a chamfer on the superior and inferior faces at the insertion end, and a beveled edge along a perimeter of the superior and inferior faces.
- the implant may
- the superior and inferior surfaces 28, 30 preferably have projections, such as teeth 32, for engaging the adjacent vertebrae. Teeth 32 on superior and inferior surfaces 28, 30 preferably provide a mechanical interlock between implant 22 and the end plates by penetrating the end plates. The initial mechanical stability afforded by teeth 32 minimizes th
- the affected vertebrae are c distracted using a lamina spreader or a lateral distractor, both of which are commonly knowr in the art. In the latter case, screws may be inserted through the pedicles into the vertebrae to interface with the lateral distractor.
- the transforaminal window 54 is created by removing the inferior facet 56 of the cranial vertebrae and the superior facet 58 of the caudal vertebrae using one or more osteotomes 59
