Decompressive laminectomy is the most common type of surgery done to treat spinal stenosis. This surgery is done to relieve pressure on the spinal cord or spinal nerve roots caused by age-related changes in the spine and to treat other conditions, such as injuries to the spine, herniated discs, or tumors. In many cases, reducing pressure on the nerve roots can relieve pain and allow you to resume normal daily activities.
Laminectomy removes bone (parts of the vertebrae) and/or thickened tissue that is narrowing the spinal canal and squeezing the spinal cord and nerve roots. This procedure is done by surgically cutting into the back.
In some cases, spinal fusion (arthrodesis) may be done at the same time to help stabilize sections of the spine treated with decompressive laminectomy. Spinal fusion is major surgery, usually lasting several hours. There are different methods of spinal fusion:
Why It Is Done ?
Most spinal stenosis occurs in the lower (lumbar) back. If you have stenosis in the neck (cervical) area, your health professional may recommend surgery because this condition can cause spinal cord and nerve damage and paralysis.
Complications from spinal stenosis surgery may result from the impact of other existing medical problems and the severity of the spinal problem. In addition, all surgery poses risks of complications. These complications may be more serious in an older adult.
