What is Superion?
Superion®, a product of VertiFlex, Inc., is an FDA-approved, minimally invasive procedure to treat lumbar spinal stenosis.
What is Lumbar Spinal Stenosis?
Lumbar spinal stenosis is a degenerative disease that causes the narrowing of the lumbar spinal canal and compression of the spinal nerves. This can result in:
- Pain in the leg, buttock, and groin
- Weakness, stiffness, cramping or numbness in the legs and buttocks
Lumbar spinal stenosis causes difficulty in walking or standing, with relief while sitting down.
How does Superion Work?
While walking or standing, the spine is in extension, increasing pressure on the spinal nerves. The Superion device is implanted in the spine and limits spine extension, producing the relief that you would get in a seated or flexed position. FDA trials have demonstrated the effectiveness of Superion in relieving symptoms and improving function 60 months after the procedure.
When is Superion Indicated?
The Superion procedure is ideal if you have no relief from conservative treatments but do not wish to undergo an invasive surgical procedure such as a laminectomy.
Procedure for Implanting the Superion Device
The Superion device has an anatomical design that takes into consideration your safety and comfort. It is available in multiple sizes and your doctor selects the size that is appropriate for you. The device is inserted through a dime-sized incision over your spine with minimal blood loss and tissue damage. It is placed at the appropriate spinal level between the spinous processes and limits spine extension though it permits spine movements.
Advantages of Superion
This minimally invasive procedure has a short operating time and recovery is quick. The stability of the spine is not compromised. Single-use instruments are used, minimizing the risk of infections. Your doctor will discuss any other risks associated with the procedure.
