•  With the working portal appropriately docked on the level of pathology, an initial exposure can be performed.

•  Often there are residual paraspinal muscle fibers that must be removed from the lamina.

•  Once the lamina is exposed, a high-speed burr is used to perform a laminectomy. Bone is removed until only the flavum is visualized.

– The laminectomy is extended laterally through the pars interarticularis.

– Bone is saved in a bone trap.

•  The laminectomy is extended cranially until the end of the flavum insertion is identified.

– Epidural fat or dura is often seen.

•  This marks the cranial extent of the laminectomy.

•  The burr is then directed directly laterally through the pars interarticularis.

•  Once the burr is through the pars, the inferior articular process can be removed, completing the facetectomy and exposing the involved disk space.
