Lumbar decompression surgery is a type of surgery which is used to treat compressed nerves in your lower (lumbar) spine. Decompression surgery is recommended only when conventional treatments(non-surgical treatments) fail to improve the condition. The surgery helps to improve symptoms like pain in the back and numbness in the legs caused due to pressure on the nerves in the spine.

What Is Lumbar Decompression Surgery?
Lumbar decompression is a surgical procedure which is performed to relieve the pressure and to alleviate pain caused by compressed nerves on the spinal cord. The decompression surgery helps to create space by removing or adjusting the vertebra covering your spinal canal. Nerve compression is often caused due to arthritis, enlargement of joints, bulging discs, bone spurs, and thickening of ligaments etc.

What Happens During Lumbar Decompression Surgery?
If a patient has to undergo lumbar decompression surgery, the dural sac and the traversing and the exiting nerves are thoroughly decompressed. The nerves will be relieved from the compression, and the compromised microvascular blood supply will be restored.

One of the following procedure is recommended in treating lumbar decompression surgery:

  • Laminectomy: Laminectomy is a surgical procedure performed to create space by removing the lamina of the vertebra which covers the spinal canal. It is also called a decompression surgery that enlarges the spinal canal and relieves pressure on the spinal cord or nerves.
  • Laminotomy and Interlaminar Decompression: This procedure is the procedure of choice as nowadays complete laminectomy is not being replaced by Laminotomy and fenestration procedures. These involve making a small hole in the lamina for during the appropriate decompression and instead of classical laminectomy
  • Discectomy: A discectomy is a surgical procedure involved in removing abnormal disc compressing the nerve root or the spinal cord — the pressure created by the intervertebral disc results in intense pain, muscle weakness by radiating nerves.
  • Spinal Fusion: Spinal fusion is a technique that corrects vertebral bone problems. This procedure involves fusing of two vertebral bones together to stabilize and strengthen the spine.
  • Foraminotomy: Foraminotomy surgery helps to relieve pressure on nerves caused by the intervertebral foramina. It is a passage through which the nerve bundles passes through bones of the vertebrae of the spine. This technique is employed when the height of the foramen collapses and forms a pinched nerve due to disc degeneration.

Recovery From Lumbar Decompression Surgery
Recovering from lumbar decompression surgery depends on various factors like complexity of the surgery, level of mobility before the operation, preoperative patient medical conditions etc. That is why, for some people, a course of physiotherapy is suggested before the operation.
