Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults aged 18-65 who have chronic coccygodynia lasting at least three months and have not responded to conservative treatments.
✕Probably not a fit
Patients who have had previous surgeries in the coccyx region or have undergone recent interventional procedures in the lumbar or sacral areas may not benefit from this study.

What this trial studies
This clinical trial evaluates the effectiveness of two interventional pain management techniques, the impar ganglion block and the sacral erector spinae plane block, in treating patients suffering from coccygodynia, or tailbone pain. Patients who have experienced chronic coccygodynia for at least three months and have not found relief from conservative treatments will be recruited for the trial. The procedures will be performed under sterile conditions with ultrasound or fluoroscopic guidance to ensure accuracy and safety. The study aims to determine which technique provides better pain relief and overall patient outcomes.
Why it matters
Potential benefit: If successful, this study could provide patients with a more effective treatment option for managing chronic tailbone pain.
How similar studies have gone: While the specific comparison of these two techniques may be novel, both approaches have been utilized in pain management with varying degrees of success in other studies.

Inclusion Criteria: * Those who have had chronic coccygodynia for at least 3 months * Being between the ages of 18-65 * Patients who do not respond to conservative treatments (analgesics, physical therapy modalities etc.) and are scheduled for interventional pain procedures Exclusion Criteria: * Patients who have undergone surgery to the coccyx region * Having undergone an interventional pain procedure in the lumbar, sacral and coccyx regions within the last year * Patients with systemic infection, local infection at the application site, and coagulopathy * Pregnant and breastfeeding patients * Having endocrine or rheumatological disease that may affect the musculoskeletal system in the relevant region and lead to diagnostic complexity (such as spondyloarthropathy) * Patients with musculoskeletal system pathology that may contribute to symptoms in the relevant region and affect the evaluation of treatment results (such as lumbar disc herniation, sacroiliitis, spinal stenosis) * Those with lumbar, sacral or coccygeal vertebra fractures * Those with a history of allergic reactions to the contents of the injectate to be administered during an interventional pain procedure (especially contrast agent and local anesthetic) * Those with mental disorders that may affect the evaluation during the follow-up periods during the study
