Foraminal Stenosis


Foraminal Stenosis

At the Minimally Invasive Spine Institute, we offer foraminal stenosis treatment that is innovative and minimally invasive. Quite similar tospinal stenosis, foraminal stenosis can affect one or more areas of your spine. To understand foraminal stenosis, also called neural foraminal stenosis, first let’s define a foramin. The nerves in the spinal canal will exit at each disc space level through a small tunnel on each side of the spine called a foramin. The borders of the foramin are the disc in the front and the facet joint in the back. Problems to either of these structures, such as bone spurs, disc bulges and disc degeneration or herniation, can form debris and lead to narrowing of this space called foraminal stenosis. Other common causes of neural foraminal stenosis are spondylolisthesis, synovial cyst and scoliosis. This can cause pinching of the nerve that is exiting through the foramin, giving symptoms of a pinched nerve. Although not all foraminal stenosis cases must be treated, some are critical and if ignored, loss of function may occur and nerves can become irreversibly damaged. That’s why it is important to see a spine specialist well versed in the latest foraminal stenosis treatment.


  • Numbness
  • Weakness
  • Sensations of burning, tingling, and pins and needles in the affected extremity (arms, legs)


The treatment of foraminal Stenosis is dependent of the etiology or cause of the stenosis. The goal of treatment is to increase the opening for the nerves along the side of the spine. For mild to moderate foraminal stenosis, a simple decompressive procedure performed either endoscopicly or through an incision less than one-inch may be effective. For cases of severe foraminal stenosis, or structural abnormalities such as scoliosis and spondyloslisthesis, a stabilization procedure is usually performed in addition to the decompression. These foraminal stenosis treatments can also be performed through an incision less that one-inch in length, allowing for a faster recovery. We can accomplish this by minimizing the damage to surrounding tissues, including muscle, so our foraminal stenosis treatment allows you to get back to life as quickly as possible.
