Many treatment techniques have been used for refractory lumbar facet joint pain; however, their efficacy has been controversial. In this study, we investigated the clinical efficacy and safety of intra-articular pulsed radiofrequency for the treatment of refractory lumbar facet joint pain in patients with low back pain.
Twenty patients with refractory lumbar facet joint pain were recruited, and each patient was treated via intra-articular pulsed radiofrequency. The treatment effects were measured with a numerical rating scale, and the technical accuracy of intra-articular pulsed radiofrequency treatment was evaluated independently by 2 radiologists. Any adverse events or complications also were checked.
We performed intra-articular pulsed radiofrequency treatment at 48 levels of the lumbar facet joints in 20 patients (5 men and 15 women; mean age, 64.50 ± 10.65 years) with refractory lumbar facet joint pain. Pain scores were significantly reduced at 1 month, 3 months, and 6 months after treatment (P < 0.05). The face validity revealed good intraarticular pulsed radiofrequency results in all 20 patients, without any serious adverse effects.
Treatment using intra-articular pulsed radiofrequency is an alternative to other techniques in patients with refractory lumbar facet joint pain.
许多治疗技术已被用于治疗难治性腰椎小关节疼痛；然而，它们的疗效一直存在争议。在本研究中，我们调查了关节内脉冲射频治疗下腰痛患者难治性腰椎小关节疼痛的临床疗效和安全性。
招募了20例难治性腰椎小关节疼痛患者，每位患者均接受关节内脉冲射频治疗。用数字评分量表测量治疗效果，并由2名放射科医生独立评估关节内脉冲射频治疗的技术准确性。还检查了任何不良事件或并发症。
我们对20例（5例男性和15例女性；平均年龄64.50±10.65岁）难治性腰椎小关节疼痛患者的48个腰椎小关节水平进行了关节内脉冲射频治疗。治疗后1个月、3个月和6个月时疼痛评分显著降低（P<0.05）。表面效度显示，所有20例患者的关节内脉冲射频治疗效果良好，无任何严重不良反应。
对于难治性腰椎小关节疼痛患者，关节内脉冲射频治疗是其他技术的一种替代方法。
