Vertiflex is a minimally invasive indirect spinal decompression procedure done for lumbar spinal stenosis. Spinal decompression means lifting the pressure exerted by the narrowed spinal canal on the spinal nerves. This situation is present in lumbar spinal stenosis. It is an outpatient procedure and is usually done under x-ray guidance, local anesthesia and IV sedation.  A very small skin incision is used and the patient usually goes home few hours after the procedure. The procedure involves placement of a small metallic implant called Superion at the narrowed spinal level(s). This implant is designed to work as an extension blocker at the treated lumber spinal level(s) where there is significant spinal stenosis. Blocking extension at the narrowed spinal level(s) prevents the additional narrowing that would happens to the already narrowed lumbar spinal canal with spine extension, as during standing and walking. This effect keeps the spinal canal open, alleviates the pressure on the spinal nerves at the treated level(s) and as a result significantly improves the patient’s symptoms of spinal stenosis. The expected result is decreasing back and leg pain and increasing the patient’s walking distance.
