While this technique can restore lumbar lordosis, it typically requires substantial reaming of the posterior aspect of the vertebral endplate. The LT-CAGE™ Lumbar Tapered Fusion Device restores lordosis and sagittal balance through a tapered implant design. Placement of the LT-CAGE™ Device with the Lumbar Tapered Instruments allows for symmetrical distraction of the vertebral bodies and significantly less reaming of the ver
