LUMBAR STENOSIS
Disorder Treatment
|
Non-surgical Treatment
The first line of treatment is almost always non-surgical. The exception is when there is bladder or bowel incontinence or progressive weakness. A vast majority of patients suffering from leg pain will naturally recover given time and non-operative treatment. Non-operative treatments include strengthening exercises, physical therapy, chiropractic, acupuncture, traction, epidural injections, pain medications, and anti-inflammatory medications including steroids.
For buttock or leg pain and mild weakness (radicular symptoms), generally at least 6 weeks of non-operative treatment is pursued to monitor for natural recovery. The waiting period is based on the knowledge that 80-90% of radicular symptoms are known to spontaneously recover. If recovery is progressing, more non-operative treatment may be prescribed.
For isolated low back pain, generally at least 6 months of non-operative treatment is pursued to monitor for natural recovery. The waiting period is based on the knowledge that most midline low back pain is known to spontaneously recover within 6 months.
Surgical Treatment
Surgical treatment for may be suggested to treat pain that has not responded to non-operative treatment or if there is severe neurologic deficit such as bowel or bladder incontinence or progressive weakness in vital muscle groups. With the exception of the presence of severe neurologic deficits, the decision to proceed with surgery is a quality of life decision.
Surgical options for a lumbar spinal stenosis are listed below. These surgical options often include a combination of surgical treatments (i.e. decompression, fusion, instrumentation). For a detailed explanation of the individual treatments, please visit the Surgical Treatments section of the web site.
- Lumbar Laminectomy/Foraminotomy
With this procedure, the lamina and overgrown facet joints are removed to make room for the nerves. This is the most common treatment for lumbar stenosis where there is bilateral buttock/leg symptoms.
- Lumbar Laminotomy/Foraminotomy
This procedure is used to remove part of the lamina and overgrown facet joint to relieve unilateral leg symptoms.
- Lumbar Laminectomy and Posterior Fusion with Instrumentation
With this procedure, the compression on the nerves is relieved and the motion between the vertebrae arrested by placement of bone and instrumentation to hold the vertebrae together until they fuse. This procedure is helpful when there is abnormal motion between vertebrae (spondylolisthesis). Arguably, the instrumentation increases the chance of fusion.
- Lumbar Laminectomy and Posterior Fusion without Instrumentation
With this procedure, the compression on the nerves is relieved and the motion between the vertebrae arrested by placement of bone to allow the vertebrae to fuse together. This procedure is helpful when there is abnormal motion between vertebrae (spondylolisthesis).
- Minimally Invasive Procedures
Posterior foraminotomy can be performed through tubes. Laser decompression and disc removal have also been performed with mixed results.
- Anterior Lumbar Fusion, Lumbar laminectomy, Posterior Fusion with Instrumentation
In patients who develop severe deformities including lumbar flatback or lumbar scoliosis, a combined anterior fusion and posterior decompression and fusion with instrumentation may be necessary to restore the normal alignment of the lumbar spine. This procedure allows excellent restoration of the disc height which is helpful for restoring normal curvature of the spine and decompressing the narrowed foramen. The fusion rate is also shown to be higher than posterior fusion alone since there is additional surface area for fusion.
- Lumbar Laminectomy, Lumbar Interbody Fusion, Posterior Fusion with Instrumentation
With this procedure, similar to the above procedures, the compression of the nerves is relieved and motion between the vertebrae arrested. In addition, the disc space height is restored which is helpful for restoring normal curvature of the spine and decompressing the narrowed foramen. The fusion rate is also shown to be higher than posterior fusion alone since there is additional surface area for fusion. The interbody procedure is also referred to as "PLIF" (Posterior Lumbar Interbody Fusion) or "TLIF" (Transforaminal Lumbar Interbody Fusion) based on how the interbody is approached.
