Coccygeal Nerve Radiofrequency Treatment in Coccydynia

Study Overview
=================
Brief Summary
-----------------
Coccydynia or coccygeal pain is a painful syndrome that affects the coccyx region. The most important etiological factors in the formation of coccidynia are; external and internal trauma. Patients with coccydynia typically complain of coccyx pain. This pain increases with prolonged sitting, bending backwards during sitting, standing for long periods of time, and standing up after sitting. Conservative treatments such as nonsteroidal anti-inflammatory drugs (NSAIDs), levator sudden relaxation exercises, seat cushions, and transcutaneous electrical simulation have all been used to relieve pain, but these methods are ineffective in 10% of patients. In the patient group unresponsive to conservative treatments, there are various interventional treatment options, including caudal epidural steroid injection, ganglion impar blocks, radiofrequency ablation of the sacral nerves, block of the coccygeal nerves and radiofrequency ablation, and coccygectomy.

Detailed Description
-----------------
In algoloji clinic, routinely apply ultrasound-guided coccygeal nerve block and radiofrequency ablation to patients with coccydynia. During the procedure, after imaging the sacral and coccygeal corns with ultrasonography, a radiofrequency ablation needle is inserted at the level of the coccygeal horn and radiofrequency ablation is applied at 90 degrees for 60 seconds. Patients are followed for a while in our post-procedure service for possible hypotension and allergic reactions. In this study, it was planned to apply the Visual Pain Scale (VAS) and Paris Functional Coccydynia Questionnaire at the 1st week, 1st month and 3rd months after the treatment to patients who had coccygeal nerve block and radiofrequency ablation in our clinic due to the complaint of coccydynia resistant to conservative treatment methods. In this way, it is planned to evaluate the efficacy of treatment.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Paris Functional Coccydynia Questionnaire | It is a scale that measures the severity of coccygeal pain. Scored between ''0: no pain'' and ''10: worst pain. | 4 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Visual analog scale (VAS) | It is a scale that measures the severity of pain. In this questionnaire, the patient's pain in sitting position, getting up from sitting position, standing and walking, traveling and at night is recorded. Scored between ''0: no pain'' and ''10: worst pain. | 4 weeks |
