Endoscopic Lateral Recess Decompression

Speaker  A 49 year old woman with five years of progressively worsening right lower extremity pain and sensory symptoms in an L5 distribution presented to my office. Her symptoms persisted despite physical therapy, medications and epidural steroid injections. She was neurologically intact on physical exam, and radiographs revealed no substantial structural abnormalities. Mri showed bilateral lateral recess stenosis due to spondylosis at L4 five and no other notable sites of stenosis. We decided to proceed with an endoscopic right L4 five lateral recess decompression. After induction of anesthesia, the patient is positioned prone on a Wilson frame. An ESP block is performed using Fluoroscopic guidance. A 15 degree seven millimetres arthrex endoscope is inserted through a subcentimeter skin incision. I find it useful to place an endoscope passport dam over the working channel to maintain fluid pressure, minimize bleeding, and optimize visualization during these cases. The trailing edge of the L4 lamina is identified, and a 3.5mm coarse diamond NSK drill is used to create a hemilaminotomy. It is important to perform sufficient bony resection to decompress the traversing nerve root, but maintain enough pars and facet to minimize the chance of iatrogenic fracture or instability. I taper my hemilaminotomy to become narrower as I move cranially to preserve the pars. Additionally, I initially on the side of removing less bone laterally. The hemilaminotomy is continued cranially until the origin of the Ligamentum flavum is identified. Different techniques exist for removing the Ligamentum flavum. These include piecemeal removal with a kerosene punch and an Enbloc Phlebectomy. I personally perform a hybrid technique in which I use a blunt probe to detach the ligamentum cranially and then open the midline raphe. Speaker  A kerosene and or pituitary rongeur can then be used to remove the ligamentum in larger pieces, revealing the thecal sac and traversing L5 nerve root below. Flavum removal is carried down all the way to the leading edge of the L5 lamina, some of which can be removed with the drill or the kerosene punch to afford additional dorsal decompression as needed. More caudal decompression is often necessary in the setting of degenerative spondylolisthesis, often extending to the level of the mid L5 pedicle. Once the traversing nerve root is directly visualized, additional medial facet and ligamentum can be resected with the drill or the kerrison punch until the nerve has been unroofed. The angled optics and low profile of the endoscope allow for facet joint undercutting, and an excellent lateral recess decompression that minimizes facet resection. At the conclusion of the procedure, the lateral aspect of the traversing nerve root should be directly visualized and the nerve should be free and mobile. The disc space is inspected to confirm that there is no ventral pathology that needs to be addressed. Hemostasis is confirmed and the incision is closed. Patients are discharged home the same day. This patient's surgery and postoperative course was uneventful. She had immediate and complete resolution of her radicular symptoms. At her most recent follow up visit, she gave me a big hug as she cried tears of joy. In summary, endoscopic lateral recess decompression allows surgeons to alleviate lumbar radiculopathy in an elegant and ultra minimally invasive manner.
