OBJECTIVE: To compare the analgesic effects between the blockade and bipolar thermal radiofrequency in the treatment of @entity158 . METHOD: Prospective, randomised and experimental study conducted on 60 @entity1 selected in the two hospitals over a period of nine months, who had intense @entity158 (Visual Analogue Scale [VAS]>6) that lasted more than 3months. @entity1 were randomised into three groups (n=20): GroupA (two intra-articular sacroiliac injections of local anaesthetic/corticosteroid guided by ultrasound in 7days). GroupB: conventional bipolar radiofrequency   palisade  . Target points were the lateral branch nerves of S1, @entity69212 , distance needles 1cm. GroupC: modified bipolar radiofrequency   palisade   (needle distance >1cm). @entity1 were evaluated at one month, three months, and one year. Demographic data, VAS reduction, and side effects of the techniques were assessed. RESULTS: One month after the treatment, @entity158 reduction was >50% in the three groups P<.001. Three and 12months after the technique, the @entity1 of the groupA did not have a significant reduction in @entity158 . At 3 months, almost 50% @entity1 of the groupB referred to improvement of the @entity158 (P=.03), and <25% at 12months, and those results were statistically significant (P=.01) compared to the baseline. GroupC showed an improvement of 50% at 3 and 12months (P<.001). All @entity1 completed the study. CONCLUSIONS: Bipolar radiofrequency   palisade  , especially when the distance between the needles was increased, was more effective and lasted longer, compared to join block and @entity230 , in relieving @entity158 sacroiliac joint.
