1. Procedure Overview
Lumbar spinal stenosis surgery is performed to relieve pressure on the spinal cord or nerves in the lower back caused by narrowing (stenosis) of the spinal canal. This condition can lead to leg pain, numbness, or difficulty walking. Common surgical procedures include:
Laminectomy (Decompression Surgery): Removal of part of the vertebra (lamina) to create more space for the spinal cord and nerves.
Laminotomy: Partial removal of the lamina, preserving more of the natural structure.
Spinal Fusion: Sometimes performed alongside laminectomy to stabilize the spine by permanently connecting two or more vertebrae.
Minimally Invasive Decompression: Using smaller incisions and specialized instruments to achieve the same goal with less tissue damage and faster recovery.
The choice of technique depends on the severity of the stenosis and the patient’s overall health.
2. Type of Anesthesia
This surgery is performed under general anesthesia, ensuring the patient is unconscious and pain-free during the procedure.
3. Possible Risks and Complications
Infection
Bleeding
Nerve injury (leading to numbness, weakness, or pain)
Spinal fluid leak
Blood clots
Continued or recurrent symptoms
Risks related to anesthesia
4. Hospital Stay Duration
The typical hospital stay is 1 to 4 days, depending on the complexity of the surgery and the patient’s post-operative condition.
5. Important Post-Operative Care
Pain management and wound care
Physical therapy to improve mobility and strength
Avoiding bending, lifting, or twisting during recovery
Use of a back brace if recommended
Follow-up imaging and assessments to monitor healing
Gradual return to normal activities over several weeks.
