Comparison of Single- and Double-Level Radiofrequency Ablation for Chronic Coccydynia
Recruiting now · Not applicable
Conditions studied: Chronic Coccydynia
In brief
This study aims to compare two commonly used radiofrequency ablation (RFA) techniques for the treatment of chronic tailbone (coccyx) pain, also known as coccydynia. Chronic coccydynia can significantly impair daily activities and reduce quality of life, particularly in patients who do not respond adequately to conservative treatments. Participants in this study will be randomly assigned to receive either a single-level or double-level radiofrequency ablation (RFA) procedure targeting the coccygeal nerve pathways. These procedures are minimally invasive and are routinely performed in pain management practice. The primary objective of the study is to determine which technique provides superior pain relief and functional improvement. Patients will be followed for up to two months after the procedure, and pain intensity and quality of life will be evaluated using validated outcome measures. The results of this study may help optimize interventional treatment strategies for patients suffering from chronic coccydynia.
