Reasons for ProcedureA laminectomy is usually done to help take pressure off your spinal cord or a nerve running out from your spinal cord. It is also done to gain access to the spinal cord, bones, and discs that are below the lamina. Herniated discs , bony spurs, or other problems can cause narrowing of the canals that the nerves and spinal cord run through. This can irritate the nerve if it gets too narrow. Often, a laminectomy is done along with a disk removal to help make the canal larger and take pressure off the nerve being irritated. When the spinal cord or other nerves get irritated, they can cause:
- Pain in an arm or leg
Possible ComplicationsProblems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
- Blood clots
- Damage to nerves, resulting in pain, numbness, tingling, or paralysis
- Problems related to anesthesia
- Another medical condition, particularly heart or lung problems
- Increased age
