Spinal Stenosis

What is the Spinal Stenosis?

Spinal stenosis results from new bone and soft tissue growth on the vertebrae, which reduces the space in the spinal canal. When the nerve roots are pinched, a painful burning, tingling and/or numbing sensation is felt from the lower back down to the legs and sometimes all the way to the feet.

Lumbar Spinal Stenosis

If you are over age 50 and suffer from lower back pain that is relieved when bending over or sitting down, you may be experiencing the symptoms of lumbar spinal stenosis (LSS) — a degenerative, age-related narrowing of the lower spinal canal that causes pressure on the nerves and leads to pain and immobility.

LSS is a common condition, with 1.2 million Americans diagnosed and treated each year.1

Treatment

The traditional treatment continuum for LSS includes conservative care, such as physical therapy, acupuncture, exercise and chiropractic; as well as symptom management with medications, epidural steroid injections (ESIs), pain pumps and/ or neuromodulation. However, these treatments do not remove the source of the pain, and, in most cases, symptoms return.

In the past, the next line of treatment for LSS included open surgical procedures such as laminotomy (partial removal of the lamina, a plate of bone in the vertebrae) laminectomy (removal of the entire lamina and the ligaments that are attached to it) and/or fusion. Each of these has risk factors and leads to changes in the natural anatomy and structural stability of the spine. Northwest Orthopaedic Specialists, P.S. offers LSS patients a new treatment alternative called mild*. Developed to remove the source of LSS symptoms earlier in the treatment continuum, mild is a groundbreaking new procedure that safely and therapeutically reduces pain and improves mobility while maintaining the spine’s structural stability. Many mild patients report immediate relief, and most go home the same day. mild provides relief for patients by addressing a primary cause of LSS. During the procedure, the physician uses mild devices to remove small pieces of bone and the tissue causing the pressure on the nerves. Performed under image guidance through a 5.1-mm mild Portal (about the diameter of a pencil), mild requires only an adhesive bandage for closure.

The mild procedure and devices have been proven safe and effective in several clinical studies. Data have shown that mild patients experienced consistent, statistically significant improvement in pain and function as well as physical well-being following treatment.3 No major adverse events related to the devices or the procedure have been reported.2,3
