Lumbar Laminectomy (Lumbar Decompression Surgery)
Lumbar laminectomy—also called lumbar decompression surgery—relieves pressure on the spinal cord and nerve roots in the lower back by removing part of the lamina (the bony roof over the spinal canal) and any thickened ligament or disc material causing narrowing. It is a standard treatment for lumbar spinal stenosis when leg pain, numbness, or weakness persist despite conservative care, with the goal of restoring walking ability and quality of life.

Symptoms and Signs of Lumbar Laminectomy (Lumbar Decompression Surgery)
Lumbar spinal stenosis often causes progressive leg symptoms during walking or standing—sometimes called neurogenic claudication. When symptoms limit daily function or threaten nerve function despite physical therapy, injections, and medicines, lumbar laminectomy may be recommended to decompress the nerves.
- Leg pain, heaviness, cramping, or fatigue that worsens with walking or prolonged standing and often improves with sitting or bending forward (shopping-cart sign).
- Numbness, tingling, or burning in the buttocks, thighs, legs, or feet.
- Weakness in the legs or feet, difficulty climbing stairs, or foot drop in more severe cases.
- Lower back pain, which may be present but is often less disabling than leg symptoms.
- Reduced walking distance and need for frequent rest breaks during daily activities.
- Bladder or bowel changes or saddle anesthesia—these are rare but urgent red flags requiring immediate evaluation.
