Lumbar Radiofrequency Ablation (RFA) is a minimally invasive procedure used to provide long-lasting relief from chronic lower back pain. This procedure is typically recommended for patients whose pain originates from the lumbar facet joints, which connect the vertebrae in the lower spine. Conditions that may benefit from RFA include:
- Facet joint arthritis
- Degenerative joint disease
- Facet joint syndrome
- Chronic lower back pain
RFA works by using heat generated by radiofrequency energy to target and disrupt the medial branch nerves, which carry pain signals from the lumbar facet joints to the brain. By deactivating these nerves, the procedure helps block pain transmission and provides relief.
How Does It Help?
Lumbar RFA is designed for patients who have had successful, but temporary, pain relief from a lumbar medial branch block. The procedure offers longer-lasting pain relief, often for several months or even years, allowing you to resume normal activities with reduced discomfort.
Steps of Administering Lumbar Radiofrequency Ablation
- Preparation:
- You will lie face down, and the skin over your lower back will be cleaned and sterilized.
- A local anesthetic will be injected to numb the skin and tissues around the treatment area.
- Fluoroscopic Guidance:
- The doctor will use fluoroscopy (X-ray guidance) to place a small needle near the medial branch nerves located around the lumbar facet joints.
- Radiofrequency Application:
- After confirming the needle’s position, a small electrode is inserted through the needle to deliver radiofrequency energy.
- The radiofrequency current heats the targeted nerve tissue, disrupting the pain signals.
- Post-Procedure Monitoring:
- You will be monitored for a brief period after the procedure, typically 15-30 minutes, to ensure there are no immediate side effects.
When Can You Go Home?
- Most patients are able to go home within an hour after the procedure.
- It is recommended to have someone drive you home, as you may experience mild soreness or numbness in the treated area.
- You can resume light activities the next day, but avoid heavy lifting or strenuous activities for 24-48 hours.
How Many Procedures Are Needed?
- One Procedure: Most patients only need one RFA treatment to experience significant pain relief, but results vary.
- Duration of Relief: Pain relief can last anywhere from 6 months to 2 years, depending on the individual. If the pain returns, the procedure can be repeated.
Final Thoughts
Lumbar radiofrequency ablation is an effective, minimally invasive treatment for chronic lower back pain caused by facet joint issues. While it doesn’t cure the underlying condition, it can provide lasting relief, allowing you to engage in physical therapy or daily activities with reduced pain.
