Lumbar Laminectomy
What is it?
Lumbar Laminectomy is a surgical procedure performed on the lower back, or lumbar region of the spine. This surgery primarily aims to relieve pressure on the spinal cord or nerve roots, which can be caused by conditions such as spinal stenosis (narrowing of the spinal canal), herniated discs, tumors, or arthritis.
Patients who undergo a lumbar laminectomy typically suffer from chronic back pain, numbness, weakness, or reduced flexibility in the legs and lower back. These symptoms often arise because the spinal cord or nerve roots are compressed, a condition that can significantly impair daily activities and overall quality of life.
This procedure is typically recommended for patients who have significant symptoms of spinal nerve compression that have not improved with conservative treatments, such as physical therapy, medication, or injections.
Recovery from lumbar laminectomy varies from patient to patient. It typically involves a short hospital stay, rest, and a gradual return to activity. Physical therapy is often part of recovery, helping patients strengthen their back and improve flexibility.
Procedure
“Laminectomy” refers to removing the lamina, the back part of the vertebra that covers the spinal canal. By removing the lamina, the surgeon creates more space in the spinal canal, thereby relieving pressure on the spinal cord or nerve roots.
During the procedure, the patient is under general anesthesia. The surgeon makes an incision in the lower back over the affected vertebrae. The muscles and soft tissues are moved aside to expose the spine. The surgeon then carefully removes the lamina and potentially other small portions of the bone, as well as any bone spurs or ligaments that are contributing to the compression.
The primary benefit of lumbar laminectomy is the relief from pain and other symptoms caused by nerve compression. Many patients experience significant improvement in their ability to walk and perform daily activities without pain. The procedure can also prevent further spinal nerve damage.
