Minimally Invasive Decompressive Lumbar Laminectomy

When the spinal nerves are pinched by a narrowing of the sides of the spinal canal, doctors at the Florida Hospital Celebration Health Spine Center may recommend a decompressive lumbar laminectomy. This minimally invasive procedure will relieve pressure on the spinal card or spinal nerve roots by removing parts of the vertebrae and thickened tissue that are causing the narrowing of the canal.

What are the symptoms of spinal stenosis?

Symptoms vary by the type of stenosis, but they can include back pain, sciatica, leg pain as you walk, numbness, or tingling in the legs. If there is compression or a dysfunction in the spinal cord, you may experience intense pain in the arms or legs, a heavy feeling in the legs, or a deterioration in fine motor skills.

How is the procedure performed?

Once you are positioned on your stomach or side, surgeons at the Florida Hospital Celebration Health Spine Center will make a small incision in the lower back so that the pinched nerve and/or compressed cauda aquina can be viewed.

Using a retractor, the vertebrae is exposed by spreading apart the muscles and fatty tissues surrounding the spine. Using a small drill or bone biting instrument, the surgeon removes a section of the vertebrae. Once an opening is cut, bone spurs and any rough edges on the intervertebral disc are removed. This enlarges the foramen and the spinal canal, relieving pressure on the spinal nerves in the process.

If required, the surgeon may also perform a spinal fusion to help stabilize the spine as part of the minimally invasive decompressive lumbar laminectomy. This involves taking a small piece of bone, usually from the patient’s hip, and grafting it onto the spine. Rods, screws, and other implants further support the spine and provide additional stability.

What should I expect after surgery?

Once the surgery is complete, your surgeon will prescribe physical therapy. Since the procedure is minimally invasive, you may be able to start therapy the very next day. However, your doctor may recommend that you restrict your activities for several weeks, including driving, lifting, or doing any strenuous work.
