When Procedure is Used
Laminectomies are usually performed when you have a herniated disc or an overgrowth of bone within the spinal canal. With a herniated disc, a laminectomy gives your surgeon access to the disc. If bony overgrowths are putting pressure on your spinal cord and nerves, a leminectory will reduce this pressure by providing more space in your spinal canal. Prior to considering a laminectomy, you will likely have already tried other conservative treatment methods such as injections and physical therapy, or you may be experiencing numbness or weakness in your muscles. In some cases, people lose bowel or bladder control as a result of compressed nerves, and a laminectomy can alleviate this pressure.
During Surgery
You will be given general anesthesia to make sure you relax your muscles and to prevent pain and help you fall asleep. Your surgeon will then make an incision in your back to move aside the muscle and remove the rear portion of the affected vertebrae and, if necessary, a herniated disc. In some cases, the surgeon will also fuse two or more bones in your spine to provide additional stability.
Risks
The risk of complications is very low. However, potential risks might include
- allergic reactions to medications
- spinal cord or nerve damage
- bleeding or blood clots
- infection
- injury to surrounding tissues
- numbness
Benefits
