Lumbar Radiofrequency Ablation

Radiofrequency ablation (RFA) is a minimally invasive procedure performed by Dr. Maloney to treat low back pain, neck pain, and other arthritis associated pain. 

 

Special radiofrequency ablation needles are used and targeted towards the pain conducting nerves. Electricity is then used to generate heat which is transferred to the tip of special needles destroying the conductive coating of the nerve. Through this process, sensation of pain from the affected region is greatly reduced. This can result in long lasting relief from pain.

 

Conscious sedation in addition to local anesthetic is typically used for the radiofrequency ablation procedure. Total time for the procedure is around 30-45 minutes depending on the number of areas targeted. 

 

Benefits of this procedure include:

• No use of steroids

• Long lasting relief of pain

• Reduction or complete relief of pain for 1-2 years typically

• Improved mobility

• Reduce pain medication usage

• No hospitalization needed

 

During the procedure, the area is numbed with lidocaine. Then X-ray guidance is used to direct the needle to the target location. When proper needle placement is confirmed, a probe is connected to the radiofrequency generator and placed into each needle. The generator is then activated to send a small current to the needle. This testing ensures ideal placement.  Additional views are checked using Xray to ensure optimal placement as well. The nerves are numbed with additional lidocaine and then the radiofrequency protocol is activated for each target nerve. Discomfort is minimal due to sedation and local anesthetic.
