Spinal Injections
When the small facet joints of the spine become arthritic, they can be a major source of back and neck pain. A facet joint injection calms them — and confirms them as the source. Performed under live X-ray by Dr. David L. Greenwald, MD, FAANS, FACS.

A facet joint injection places anti-inflammatory medication directly into one of the small joints at the back of the spine — relieving the pain of facet arthritis and confirming the facet joint as the source. It's both a treatment and a key diagnostic step before radiofrequency ablation.

The facet joints are small paired joints at the back of each spinal segment that guide movement. When they wear down with arthritis, they can cause localized back or neck pain that worsens with bending backward or twisting. A facet joint injection delivers steroid and numbing medication right into the joint, relieving pain and confirming that the facet joint is responsible.
Back or neck pain that persists for months and becomes self-reinforcing.

Learn MoreFacet injections are considered when arthritic (facet-driven) back or neck pain hasn't responded to conservative care. Because they're diagnostic as well as therapeutic, good relief tells us the facet joint is the source — and that radiofrequency ablation is likely to give you months of relief.
Book a Consultation — (602) 566-9500Targeted relief of arthritic facet pain; confirms the pain source; quick outpatient procedure; the gateway to long-lasting ablation when appropriate.
Temporary soreness, a brief rise in pain or blood sugar, and, rarely, infection. Your surgeon reviews your specific risks beforehand.
Life Beyond the Pain

It's a quick outpatient procedure of about 15–30 minutes. Under live X-ray guidance, the needle is placed precisely into the targeted facet joint and the medication is delivered. Most patients feel only brief pressure.
You can usually return to normal activity the same or next day. Relief may last from weeks to months. When a facet injection relieves your pain but the relief fades, it's the clearest sign you're a candidate for longer-lasting radiofrequency ablation.
