What is Arthritis of the Back?
Back Arthritis (or Facet Arthropathy) is commonly referred to as arthritis of the facet joint. The facet joints break down from aging, wear and tear, injury, instability, and slipping of the spine called spondylolithesis. This wearing out of the facet joints is called degeneration. These degenerative changes may produce pain.

The most common cause of facet arthritis is osteoarthritis. “Osteo” means bone and arthritis means inflammation of joints. Osteoarthritis causes the breakdown and swelling in the cartilage of the facet joint ultimately producing bone on bone rubbing. The body tries to stop this rubbing by thickening the joint.  Arthritis of the facet joints may produce pain and stiffness. If the joints enlarge too much, they may pinch nerves causing arm or leg pain. Osteoarthritis and spinal arthritis are both common causes for back surgery at our spine clinics in Hackettstown and Newton.

How is Facet Arthritis Diagnosed?
Facet arthropathy may be diagnosed on x-rays, CT and MRI. CT scan may show thickened irregular facet joints. MRI scan may show joint swelling, thickened ligaments and bones and pinched nerves. These imaging studies only show the physical abnormality. They do not indicate if these changes are responsible for your pain.

To determine the painful structure the patient may undergo pain mapping. Facet injections are used to localize where the pain is coming from. Numbing medicine is injected into the facet joint or onto the facet nerve (medial branch nerve). If the pain is caused by the facet joint the pain will stop or decrease. If the pain does not improve then the pain is not from the facet joint, but is originating from something else, such as the bones, disks, ligaments, spinal nerves, etc.

What are the Treatment Options?
Patients who fail conservative treatment for osteoarthritis and spinal arthritis may benefit from back surgery at our Hackettstown or Newton clinic. Traditionally these patients were treated with either a large fusion surgery or radiofrequency ablation (RFA). RFA is the placement of burning electrodes blindly onto the spine under x-ray guidance to burn medial branch nerves that transmit back pain. The nerves usually recover from the injury after 6 to 9 months and the pain returns. Endoscopic Rhizotomy is a new improved treatment for back pain. The medial branch nerves are found and cut under direct visualization through the endoscope. Patients usually have almost immediate pain relief lasting for years. Recovery time ranges from one to three weeks.
