OBJECTIVE: The objective of this study was to determine the efficacy of percutaneous radiofrequency (RF) thermocoagulation of the ramus communicans nerve in @entity1 suffering from @entity1643 . METHODS: Forty-nine @entity1 who suffered @entity1643 at only 1 painful vertebral level, and whose @entity158 continued after undergoing intradiscal electrothermal annuloplasty (IDET), were randomly assigned to 1 of 2 treatment groups. The lesion group (n = 26) received RF thermocoagulation of the ramus communicans nerve. @entity1 in the control group (n = 23) received an injection of @entity3303 without radiofrequency. Visual analog scale (VAS) @entity158 scores, analgesic requirements, SF-36 subscales, and the overall @entity1 satisfaction with the procedure were tabulated. RESULTS: The average follow-up period was 4 months. The @entity1 -reported VAS @entity158 scores were significantly lower (P < 0.05) in the lesion group. The scores of the RF lesion group improved by a mean increase of 11.3 points (P < 0.05) on the SF-36 bodily @entity158 subscale, and by a mean increase of 12.4 points on the physical function subscale (P < 0.05). In a follow-up analysis within the RF lesion group, VAS @entity158 scores improved by a mean reduction of 3.32 (P = 0.001). The scores improved by a mean increase of 14.5 points (P = 0.005) on the SF-36 bodily @entity158 subscale and 15.2 points(P = 0.002) on the physical function subscale within the RF lesion group. One @entity1 in the lesion group complained of mild @entity425 , but he completely recovered at postoperative 15 days without any serious problems. DISCUSSION: In @entity1 with @entity1643 , percutaneous RF denervation of the ramus communicans nerve should be considered as a treatment option.
