Lumbar laminectomy removes bone and tissue compressing the spinal canal to relieve leg pain, cramping, and weakness caused by lumbar spinal stenosis.
Indicated for patients with symptomatic lumbar spinal stenosis causing neurogenic claudication or radiculopathy that has not responded to physical therapy, injections, or activity modification.
Performed under general anesthesia, typically taking 1 to 2 hours. The lamina and any compressing tissue are removed through a midline incision. Most patients go home within 1 to 2 days of surgery.
Risks include spinal instability requiring fusion, cerebrospinal fluid leak, infection, nerve injury, and incomplete relief.
