    Most experts recommend that people with spinal stenosis try nonsurgical treatments before choosing surgery.

    Surgery for lumbar spinal stenosis is most likely to relieve pain, numbness and weakness that are mostly in your legs. Surgery may not work as well for relieving pain that is mostly in your back.

    Surgery is usually effective if you have severe leg pain and numbness and you have not been able to move around well for a long time. But in some cases, the symptoms return after surgery. It is also possible that nerve symptoms, including numbness and clumsiness, may not be relieved or may return.

    After a laminectomy and fusion, spinal stenosis may develop directly above or below the surgery site. Repeated surgeries for spinal stenosis increase your risk of complications and instability in the spine.

    Age should not be a factor in deciding whether to have decompressive laminectomy. But if you have other medical conditions that will make this procedure and follow-up rehabilitation less successful, surgery may not be recommended.

    Complications from spinal stenosis surgery may result from the impact of other existing medical problems and the severity of the spinal problem. Also, all surgery poses risks of complications. These complications may be more serious in an older adult.

    Possible complications include:

    • Problems from having general anesthesia.
    • A deep infection in the surgical wound.
    • A skin infection.
    • Blood clots in the deep leg or pelvic veins (deep vein thrombosis), which in rare cases travel to the lungs (pulmonary embolism).
    • An unstable spine (more common after multiple laminectomies are done without using spinal fusion).
    • Nerve injury, including weakness, numbness or paralysis.
    • Tears in the fibrous tissue that covers the spinal cord and the nerve near the spinal cord, sometimes requiring a second surgery.
    • Difficulty passing urine or loss of bladder or bowel control.
    • Death (rare) related to major surgery.

    If you have diabetes or circulation problems or if you are a smoker, you may be at greater risk for complications.

    Surgery for spinal stenosis usually is elective but may be recommended if symptoms cannot be relieved with nonsurgical treatment. In general, experts feel that surgery has good results and relieves pain in the lower extremities for people who have severe symptoms of spinal stenosis and who have few other serious health problems.

    Research shows that:

    • Out of 100 people who had this surgery, up to 80 were satisfied with the results. This means that about 20 out of 100 were not satisfied.
    • Out of 100 people who have this surgery, 10 to 20 need to have surgery again after several years because their symptoms come back. This means that 80 to 90 out of 100 don't need a second surgery.
    • Surgery may work better than nonsurgical treatments to relieve pain and help you move better. If nonsurgical treatments have not worked well enough, surgery might be able to help you.
    • By 3 months, people who had surgery notice more improvement in their symptoms and can be more active than people who did not have surgery. This difference continues for at least 4 years after surgery.
    • The benefits of surgery appear to last for many years. After 8 to 10 years:
      • People treated with surgery were as satisfied as those treated without surgery.
      • People who had surgery were generally able to be more active and had less leg pain than those who had nonsurgical treatment.

      But symptoms may return after several years. A second surgery may be needed if:

      • Spinal stenosis develops in another area of the spine.
      • An earlier surgical procedure was not effective in controlling symptoms.
      • Instability develops, or fusion does not occur.
      • Regrowth of tissue (lamina) presses on the spinal cord or spinal nerve roots.

      Spinal fusion may be done at the same time as decompressive laminectomy. Spinal fusion may help to stabilize sections of the spine that have been treated with decompressive laminectomy. In general, fusion is only done if an area of the spine is unstable, which means the small bones can move too much. This extra movement causes wear and tear on the soft tissues, leading to irritation and pain. The goal of fusion is to keep the damaged bones in the spine from moving so that the soft tissues are protected.

    Surgery for spinal stenosis is considered when:

    • Severe symptoms restrict normal daily activities and become more severe than you can manage.
    • Nonsurgical treatment does not relieve pain, and severe nerve compression symptoms of spinal stenosis (such as numbness or weakness) are getting worse.
    • You are less able to control your bladder or bowels than usual.
    • You notice sudden changes in your ability to walk in a steady way, or your movement becomes clumsy.

    Most spinal stenosis occurs in the lower (lumbar) back. If you have stenosis in the neck (cervical) area, your doctor may recommend surgery because this condition can cause spinal cord and nerve damage and paralysis.

    The decision to have surgery is not based on imaging test results alone. Even if the results of imaging tests show increased pressure on the spinal cord and spinal nerve roots, the decision to have surgery also depends on the severity of symptoms and your ability to perform normal daily activities.

    In some cases spinal fusion will be done at the same time to stabilize the spine. Spinal fusion might make it easier for you to move around (improve function) and relieve your pain. It can also help keep the bones from moving into positions that squeeze the spinal canal and put pressure on the spinal cord.

    Depending on your health and the extent of the surgery, it may take several months or more before you are able to return to your normal daily activities.

    Decompressive laminectomy is the most common type of surgery done to treat spinal stenosis. This surgery is done to relieve pressure on the spinal cord or spinal nerve roots caused by age-related changes in the spine. It also is done to treat other conditions, such as injuries to the spine, herniated discs, or tumors. In many cases, reducing pressure on the nerve roots can relieve pain and allow you to resume normal daily activities.

    Laminectomy removes bone (parts of the vertebrae) and/or thickened tissue that is narrowing the spinal canal and squeezing the spinal cord and nerve roots. This procedure is done by surgically cutting into the back.

    In some cases, spinal fusion (arthrodesis) may be done at the same time to help stabilize sections of the spine treated with decompressive laminectomy. Spinal fusion is major surgery, usually lasting several hours. There are different methods of spinal fusion:

    • In the most common method, bone is taken from elsewhere in your body or obtained from a bone bank. This bone is used to make a "bridge" between adjacent spinal bones (vertebrae). This "living" bone graft stimulates the growth of new bone.
    • In some cases an additional fusion method (called instrumented fusion) is performed, in which metal implants (such as rods, hooks, wires, plates or screws) are secured to the vertebrae to hold them together until new bone grows between them.

    There are a variety of specialized techniques that can be used in spinal fusion, although the basic procedure is the same. Techniques vary from what type of bone or metal implants are used to whether the surgery is done from the front (anterior) or back (posterior) of the body. The method chosen depends on a number of factors, including your age and health condition, the location (lower back or neck (cervical)) of stenosis, the severity of nerve root pressure and associated symptoms and the surgeon's experience. Spinal fusion increases the possibility of complications and the recovery time after surgery.

    Laminectomy and laminotomy are surgeries done to relieve pressure on the spinal cord and/or spinal nerve roots by removing all or part of the lamina. The lamina, the thin part of the bones that make up the spine (vertebrae), protects the spinal cord.

    Age-related changes in the spine may narrow the opening through which the spinal cord runs (spinal canal), and the spinal cord and/or nerve roots may become squeezed. Laminotomy removes part of the lamina. Laminectomy removes all of the lamina on selected vertebrae. It also may remove thickened ligament tissue. The choice of procedure depends on where the spinal problem is and how bad it is. Less pressure on the nerve roots often can relieve leg or arm pain and can allow you to resume normal daily activities.

    A lumbar laminectomy is the removal of the back part of the bony structure of the vertebra. When the surgeon is removing the bone, some of the nerve roots may need to be moved and/or protected. This movement/protection of the nerve roots may cause you to experience symptoms that you did not have prior to surgery. This may be the cause of the numbness in your feet.
