The most common complications and risks associated with spinal stenosis surgery are:
A tear in the membrane covering the spinal cord at the site of the operation
Infection
A blood clot that forms in the veins.
Although these conditions can be treated, they may prolong recovery. The presence of other diseases and the physical condition of the patient are also significant factors to consider when making decisions about surgery.
Outcomes of Spinal Stenosis Surgery
Once the obstructions that are causing spinal stenosis symptoms has been removed, the patient will usually have some relief, have less leg pain, and be able to walk better. However, if nerves were badly damaged prior to surgery, there may be:
Some remaining pain
Numbness
No improvement.
Also, the degenerative process will likely continue, and pain or limitation of activity may reappear after surgery.
