Study Comparing Single- and Double-Level Radiofrequency Ablation Procedures for Long-Term Tailbone Pain Relief and Improved Function

What this Trial Is About

Researchers are evaluating two common radiofrequency ablation RFA methods for treating chronic tailbone pain, known as chronic coccydynia. This condition causes persistent pain in the coccygeal region that worsens with sitting and affects quality of life, especially for those who do not respond well to conservative treatments. The study aims to compare the effectiveness of single-level versus double-level RFA targeting the ganglion impar to determine which provides better pain relief and improved function. This is a prospective randomized controlled trial led by Marmara University. Participants will be randomly assigned to one of two groups one receiving a fluoroscopy-guided single-level RFA procedure and the other receiving a double-level RFA procedure targeting two adjacent levels. Both procedures are minimally invasive and performed under sterile conditions by experienced pain specialists using standardized techniques. The study includes baseline evaluations followed by treatments and monitoring over a two-month period. During the study, participants will be assessed at baseline, 1 hour, 3 weeks, and 2 months after the procedure. Pain intensity will be measured using the Numeric Rating Scale, while quality of life and functional status will be evaluated with validated questionnaires at baseline, 3 weeks, and 2 months. Researchers will monitor changes in pain, function, and quality of life to compare the two techniques and help improve treatment strategies for chronic coccydynia.
