This is known as "open" surgery. In some cases, it may be possible for spinal fusion to be carried out using a "keyhole" technique known as microendoscopic surgery. This is performed using a tiny camera and surgical instruments inserted through a small incision in your back.
This is the most common surgery for lumbar spinal stenosis. In this procedure, a surgeon removes parts of the bone, bone spurs, or ligaments in your back. This relieves pressure on spinal nerves and can ease pain or weakness, but the procedure can make your spine less stable.
A laminectomy can be performed at any level of the spine and using minimally invasive techniques. Patients with single-level or two-level stenosis of the lumbar spine are usually sent home on the day of surgery. A laminectomy can be used to treat spinal stenosis, degenerative disc disease, or a herniated disc.
