The Application of Radiofrequency Ablation in Acute and Chronic Pain Management.

Radiofrequency ablation (RFA), also known as rhizotomy, is one of the frequently used modalities in interventional pain management. This nonsurgical procedure delivers radiofrequency waves to the targeted nerves to interrupt transmission of nociceptive signals from the peripheral tissues to the central nervous system, thereby reducing pain perception. Recent studies have demonstrated the efficacy of RFA treatment as an effective interventional pain management technique to treat a variety of acute and chronic pain conditions including facial pain, headaches, postmastectomy, musculoskeletal, and major joint pain (knee, hip, shoulder, sacroiliac), and cancer pain.

The applications of cryoneurolysis for acute and chronic pain management.

Background: Cryoneurolysis is a term used to describe the application of extreme cold to targeted nerve tissue. The primary goal of the application of a thermal neurolytic technique is to disrupt the conduction of pain signals from the periphery to the central nervous system and eliminate or diminish the experience of pain. Recent advancements in ultrasound technology coupled with the development and approval of handheld devices specifically designed to deliver cryoneurolysis has expanded the use of this modality in the perioperative setting.
