ABSTRACT

Coccydynia is a rare but painful condition that affects the coccygeal region. The incidence is not well known but obesity and female gender are increased risk factors for developing. The management is complicated for the clinicians due to unknown etiology with no universally accepted treatment. Our aim is to evaluate the results of radiofrequency thermoablation (RFT) of ganglion impar treatment for coccydynia.

We conducted a prospective, cross sectional study including 42 patient who suffers from coccydinia. Visual Analog Scale (VAS) and Oswestry Low Back Pain Disability Questionnaire (Oswestry) score were used to determine the progression of pain under treatment.

Treatment with RFA has a better clinical outcome supported with or without medical treatment when compared with medical treatment alone.

The study included 42 patients with coccydynia. Of these 15 (% 35.7) were male and 27 (% 64,3) were female. The average body mass index(BMI) is 28,6 kg/m2 and weight 78,1kg. Men were significantly taller and heavier than women but there is no statistically difference in age, BMI, duration of pain. After six months follow-up VAS was dramatically decreased but in the first year examination, minimally increased again. Oswestry and VAS had a correlation in one year follow-up.
