Laminectomy (Spinal Decompression)
A laminectomy removes the lamina — the back portion of a vertebra — to open up the spinal canal and take pressure off the nerves. It's one of the most common spine operations, used for spinal stenosis, herniated discs, and nerve compression. The approach works in the lumbar (lower back), cervical (neck), or thoracic (mid-back) spine depending on where the problem is.

Who Needs Laminectomy (Spinal Decompression)?
Surgery makes sense when spinal stenosis is causing leg pain (claudication), weakness, or bladder and bowel problems that haven't improved after 6-12 months of conservative care. It's also done for herniated disc fragments pressing on nerves, and urgently when there's spinal cord compression that can't wait.
What to Expect
Recovery Timeline
Rest with short walks. Avoid bending, lifting more than 5 pounds, or twisting.
Gradual increase in activity. Walking encouraged as the primary exercise.
Return to desk work. Physical therapy begins to strengthen core and back muscles.
Return to moderate physical activity. Most patients experience significant nerve relief.
Full recovery and maximum nerve healing. Nerve symptoms (numbness, tingling) may continue improving for 12+ months.
Risks & Complications
- Spinal fluid leak (dural tear, 1-3%)
- Infection (1-2%)
- Nerve injury
- Recurrent stenosis requiring repeat surgery
- Spinal instability (may require fusion at same time)
- Incomplete relief of symptoms
Frequently Asked Questions
How successful is laminectomy for spinal stenosis?
70-85% of patients with lumbar stenosis get meaningful relief at 2 years. Most do well long-term, though some develop recurrent stenosis or problems at adjacent levels over time.
Is laminectomy a major surgery?
A single-level lumbar laminectomy is a moderate procedure — not trivial, but recoverable. Multi-level or cervical surgeries are more involved. Minimally invasive approaches have cut hospital stays considerably compared to traditional open surgery.
Will laminectomy fix my leg pain?
It's very effective for leg pain (sciatica or claudication) caused by mechanical compression. Numbness and weakness often take weeks to months to fully improve as the nerves recover. Back pain alone — without leg symptoms — is harder to predict.
