A laminectomy may be performed to ease pressure on the spinal nerves, remove a tumor, or treat a herniated disc. The surgery does involve removing part or all of the vertebra. Your back muscles will be able to protect your spinal nerves after a laminectomy. One way to make sure you recover optimally after a laminectomy is by going through physical therapy. Improving your strength and flexibility can reduce the risk of developing post-laminectomy syndrome.
