Abstract

BACKGROUND: Coccygodynia is a clinical condition characterized by pain and tenderness around the coccygeal region. Trauma is the most common etiologic factor. We aimed to investigate the effectiveness of pulsed radiofrequency (PRF) treatment in patients with coccygodynia that could not be relieved by classic treatment protocols and presenting our long-term results of caudal epidural PRF.
METHODS: Study included 21 patients that were treated for coccygodynia by caudal epidural PRF in our Pain Clinic. Sixteen patients (76%) had a history of trauma; three patients (14%) had previous surgery whereas two patients (10%) had idiopathic coccygodynia with no identifiable cause. All patients had been previously treated by conservative methods, but none had pain relief. Pain level of the patients was assessed by visual analog scale (VAS) score. A questionnaire to evaluate subjective patient satisfaction was also used at third week and at sixth month follow-ups.
RESULTS: Median VAS score was 8 at the beginning, decreased to 2 by the third week and measured as 2 at the sixth month. VAS at 3 week and 6 m were significantly lower compared to baseline (p<0.001). At sixth month twelve patients (57%) had excellent result, 5 patients (24%) had good results and only 4 (19%) patients had poor results regarding subjective patient satisfaction questionnaire.
CONCLUSIONS: Caudal epidural PRF may be an alternative to surgery for coccygodynia patients that are unresponsive to classic treatment methods.
