What effects does radio frequency ablation (rhizotomy) primarily achieve?

Radio frequency ablation, specifically in the context of rhizotomy, primarily achieves the destruction of the facet sensory nerve. This procedure involves using heat created by radio waves to target specific nerves responsible for transmitting pain signals from the facet joints in the spine. By disrupting these nerves, radio frequency ablation can effectively reduce or eliminate pain associated with conditions like arthritis or chronic back pain.

In this therapy, the goal is not to directly enhance mobility or strength, although pain relief may indirectly lead to improved function. It does not enhance the healing of tissues, as the primary focus of rhizotomy is on pain management rather than tissue repair. Additionally, it does not prevent future pain syndromes; rather, it addresses current pain by interfering with the nerve pathways involved in transmitting pain signals. Therefore, the process is specifically aimed at targeting sensory nerves to provide relief from pain, making this option the most accurate representation of what radio frequency ablation achieves.
