It was thought that the efficacy of pulsed radiofrequency (PRF) treatment of the medial branch in patients with lower back pain was not as long lasting as that of continuous radiofrequency (CRF) thermo-coagulation techniques.
The goal of this study was to determine the efficacy and the long-term effects of PRF treatment of the medial branch in selected low back pain patients.
We retrospectively reviewed and analyzed patients with lower back pain who underwent PRF treatment on the medial branch at our institute. Pain relief was evaluated by visual analog scale (VAS) score at pretreatment, 2 weeks, 6 months, 1 year and 2 years post-treatment. Oswestry disability index (ODI) score was evaluated pretreatment and at 2 years post-treatment. We also recorded the satisfaction period after PRF treatment.
Twenty-three patients were available for the 2-year follow-up analysis. None of the patients had any side effects or procedure-related complications during the follow up period. The average VAS score declined from 7.1 ± 2.4 pre-treatment to 2.9 ± 2.1 2 weeks post-treatment, 2.6 ± 1.8 at 6 months, 2.8 ± 2.1 at 1 year and 3.0 ± 2.5 at 2 years. The average ODI score decreased from 33.6 ± 13.6 pre-treatment to 15.3 ± 5.7 at 2 years post-treatment. Mean satisfaction period after PRF treatment was 16.6 ± 9.43 months.
PRF treatment on the medial branch is an effective and safe treatment option for patients with lower back pain.
曾有人认为，脉冲射频（PRF）治疗下腰痛患者的内侧支，其疗效不如连续射频（CRF）热凝技术持久。
本研究旨在确定PRF治疗特定下腰痛患者内侧支的疗效及长期效果。
我们回顾性分析了在我院接受内侧支PRF治疗的下腰痛患者。通过视觉模拟量表（VAS）评分在治疗前、治疗后2周、6个月、1年和2年评估疼痛缓解情况。在治疗前和治疗后2年评估Oswestry功能障碍指数（ODI）评分。我们还记录了PRF治疗后的满意期。
23例患者可进行2年的随访分析。随访期间，所有患者均未出现任何副作用或与手术相关的并发症。平均VAS评分从治疗前的7.1±2.4降至治疗后2周的2.9±2.1、6个月时的2.6±1.8、1年时的2.8±2.1和2年时的3.0±2.5。平均ODI评分从治疗前的33.6±13.6降至治疗后2年的15.3±5.7。PRF治疗后的平均满意期为16.6±9.43个月。
PRF治疗内侧支对下腰痛患者是一种有效且安全的治疗选择。
