Spinal Stenosis Surgery in New York City

When surgery is necessary for spinal stenosis, the Weill Cornell Brain and Spine Center takes the least invasive approach possible. Our spine surgeons have developed expertise in some of the most advanced minimally invasive surgery for spinal stenosis:

Lumbar Laminectomy

This is one of the most common procedures used to treat spinal stenosis today. It can be performed with open or minimally invasive techniques, depending on the diagnosis. The procedure involves removal of the lamina (the part of the vertebra that covers the spinal canal, which houses the spinal cord), bone spurs and excess ligament, thus reducing compression.

Posterior Cervical Laminectomy

Laminectomy is surgical procedure used to treat severe cases of cervical spinal stenosis. Surgery is performed under general anesthesia, and the pressure of the spine is decreased by removing the portion of the vertebrae that is compressing the spine and nerve structures. Bone grafts are inserted into the spine and held in place by rods and screws, which stabilizes the neck and creates a fusion of the vertebrae. Over time, as the neck heals, new bone grows around the screws and fuse the spine. Patients usually wear a hard, cervical collar for 6 weeks after surgery.

Minimally Invasive Lumbar Fusion

This surgery fuses the bones of the spine in the lower back together so that there is no longer any motion between them. This reduces spinal pressure, pain, and nerve damage. Minimally invasive lumbar fusions do not require the large incision or the muscle retraction typically used in conventional fusions. Patients undergoing this procedure have a fast recovery time. A recent advance is the use of a computerized image guidance system for many patients undergoing lumbar fusion. This has the advantage of aiding the surgeon in optimal placement of screws and avoiding injury to delicate nerve tissue.

XLIF (Extreme Lateral Interbody Fusion)

This advanced method of minimally invasive surgery approaches the spine from the side, avoiding the major muscles of the back. A spine surgeon makes a small incision in the patient’s side, between the lower ribs and pelvis, and inserts a special surgical instrument just above the disc space. The surgeon removes the damaged disc tissue and inserts a spacer between the vertebrae. The surgical team monitors the position and correct placement of the spacer, sometimes using special screws or a plate on the side of the spine to offer additional stability. Patients typically are walking within a few hours of the XLIF procedure and are then discharged the next day. Most patients are back to work within approximately two weeks.

Additional Information

Until recently, all patients undergoing lumbar fusion required a bone graft either from the hip region or from a bone bank. Newer bone grafting substances are now used to promote healthy fusion. In most patients undergoing lumbar spinal fusion, metal titanium instrumentation is also used. This will typically involve placing pedicle screws into the bone and connecting these with a rod.
