Considering surgeryWhat kinds of surgery are recommended for ? The type of surgery recommended depends on the cause of the
stenosis. Usually no surgery is required. In the case of stenosis of the canal due to
arthritis and aging, usually a laminectomy is all that is required. For foraminal stenosis due to a disc
herniation, a discectomy may be all that is needed. If the stenosis is caused by a more severe
condition, a fusion or more intricate spine reconstruction may be needed.
Who should consider laminectomy, decompression, fusion for and in what cases? Surgery should be considered for individuals who have failed
conservative treatment with medications and injections, or those with symptoms that
are so severe that they are starting to lose significant function and are at
risk for permanent nerve damage.What happens if nothing is done for (best case/worst case scenarios)? Most people do not have surgery to correct spinal stenosis
and their symptoms either resolve or they learn to live with them. However,
without surgery, there is a risk of permanent nerve damage and possible
paralysis.What options exist for surgery for ? The surgical options for spinal stenosis are based on the
cause of the stenosis.
For stenosis of the canal due to arthritis and aging, or due
to a small spinal canal from birth, usually a laminectomy is all that is
required.
For foraminal stenosis due to a disc herniation, a
discectomy may be all that is needed.
If the stenosis is
caused by a more severe condition, such as spondylolisthesis, fracture, tumor
or scoliosis, then a fusion or a more intricate spine reconstruction may be needed. When performed by an experienced surgeon, how effective is laminectomy, decompression, fusion for likely to be and how long will the benefit last? In the hands of an experienced surgeon, the outcomes of laminectomy,
decompression, and fusion surgery are usually effective in relieving leg and
arm pain caused by the stenosis. Usually
it takes many months for the strength and sensation to return to normal and this
may never occur, but the pain usually decreases rapidly.
How urgent is laminectomy, decompression, fusion for ? Surgery for spinal stenosis is almost always elective,
except in some very unusual cases in which permanent spinal cord damage may
occur. Usually these cases are not treated surgically until time and other more
conservative options have proven to be ineffective.
What are the most frequent and most serious risks of laminectomy, decompression, fusion for ? How common are they? The most frequent risks associated with spinal stenosis
surgery, include:
- Infection.
- Stiffness.
- Tear of the lining of the sac surrounding the
spinal cord (dural tear).
- Nerve root or spinal cord injury.
- Anesthetic complications.
These risks can be
minimized by optimizing the medical status of the patient before surgery. For
example, the use of tobacco products increases the risk of adverse events
occurring, therefore, patients are encouraged to stop smoking or using other
tobacco products. If risks occur during or after laminectomy, decompression, fusion for how are they managed? Most of the risks can be managed with medications, or on
occasion (such as with infection), with a repeat surgery. The most important thing is to identify the
problem and address it.
