Summary

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.

Conditions

  • Chronic Coccydynia

Interventions

PROCEDURE

Single-Level Ganglion Impar Radiofrequency Ablation

Fluoroscopy-guided radiofrequency ablation of the ganglion impar will be performed using a transsacrococcygeal approach. After appropriate needle placement and confirmation, thermal radiofrequency lesioning will be applied at a single level using standardized parameters.

PROCEDURE

Double-Level Ganglion Impar Radiofrequency Ablation

Fluoroscopy-guided radiofrequency ablation of the ganglion impar will be performed using a combined transsacrococcygeal and transcoccygeal approach. After appropriate needle placement and confirmation, thermal radiofrequency lesioning will be applied at two adjacent levels using standardized parameters.
