The spinal canal is the hollow passage formed by the spine, through which the spinal cord travels. Lumbar spinal stenosis refers to the portion of the spinal cord in the lower spine (lumbar region) being pinched in the canal (stenosis).
When lumbar spinal stenosis occurs, patients tend to experience pain, weakness, and/or numbness in the buttocks area while standing or walking. This type of pain or numbness is called neurogenic claudication. The pain is relieved by bending forward or sitting.
Lumbar spinal stenosis is not caused by one single factor, but actually a combination of factors. When any of the following factors happen together, lumbar spinal stenosis can develop.
Non-operative treatment is always the first line of action, as we try to avoid surgery whenever possible. Some non-operative options include: physical therapy, activity modification, and anti-inflammatory medications. If those treatments are not effective, then the next alternative would be epidural injections.
If a patient’s symptoms are not improving after non-operative treatments, or are worsening in numbness, weakness, having the inability to stand or walk, or issues with urinary or bowel function, then surgery may be warranted.
To spare the muscle and tendon attachments, this approach takes the pressure off both sides of the spine through a minimally invasive technique on only one side of the spine.
This technique uses an ultrasonic blade to make the bony cuts needed to take the pressure off the nerves. By doing this it decreases both the risk to the lining of the nerve roots, and the blood loss from the bone itself.
In order to access the spinal canal, this technique uses a very small tubular retractor to decrease injury to the muscular and tendon attachments.
