The recuperation time for surgery for spinal stenosis is six months to one year, according to Cleveland Clinic. Factors that impact recovery include the seriousness of the surgery and the rate of progress during rehabilitation. For example, if the operation included spinal fusion, the recuperative period is extended.
Spinal stenosis occurs when the spinal column becomes narrower, limiting the amount of room available for the spinal cord and nerves, explains Cleveland Clinic. If the space becomes so small that nerves are compressed, the individual experiences back and leg pain and leg weakness. Surgery has three possible approaches: removing part of the vertebrae to make more room, creating more space within vertebrae for nerve roots, or joining bones with screws or bone grafts.
