Title: Clinical outcomes of pulsed radiofrequency neuromodulation on dorsal root ganglion combined with nerve blocking for failed back surgery syndrome
Abstract: Objective To investigate the clinical efficacy of pulsed radiofrequency modulation on dorsal root ganglion combined with nerve blocking for failed back surgery syndrome(FBSS).Methods Total of 83 patients suffered from FBSS were randomized divided into two groups: control group(n=41) and treatment group(n=42).All the patients were punctured to the suffered dorsal root ganglion from the safety triangle approach using a 15 cm radiofrequency needle guided by C arm X-ray.In the control group,5 mL anti-inflammatory and analgesia solution were injected to the dorsal root ganglion after successful puncture,while in the treatment group patients were treated by pulsed radiofrequency modulation on the dorsal root ganglion for 240 seconds(42 ℃),then injected 5 ml anti-inflammatory and analgesia solution.The visual analogue scale(VAS) was evaluated before the operation,1 day,1 month,3 months and 6 months after the operation.All potential complications such as epidural infection and nerve injury were followed up after the operation.Results Although the VAS in both group were decreased significantly after treatment,compared with control group,patients in treatment group showed more pain relief at 3 and 6 months after the treatment(P0.05),and no obvious nerve injury and epidural infection occured in both group.Conclusions Pulsed radiofrequency modulation on dorsal root ganglion for patients with FBSS can receive an exact short-term and long-term efficacy;It is a safety method to treat the FBSS patient.
