The purpose of this study was to assess the efficacy of pulsed radiofrequency (PRF) applied to the suprascapular nerve for pain relief in medically unfit patients with painful cuff tear arthropathy. Twelve patients with chronic shoulder pain due to cuff tear arthropathy were recruited. The mean age was 68 years (range, 60-83 years). The suprascapular nerve was targeted at the suprascapular notch with PRF. The patients were assessed with the Oxford score, Constant score, and visual analog scale (VAS) pain score before ablation and 3 and 6 months after ablation. Statistical analysis was undertaken by use of the Friedman test. Ten patients showed improvement in the VAS score (P = .24) and Constant score (P = .005) and eleven in the Oxford score (P = .001). There was a deterioration in the VAS scores between 3 and 6 months, suggesting that the benefits were starting to wear off with time (P > .05). We conclude that PRF may be a useful therapeutic adjunct in patients with painful, end-stage rotator cuff tear arthropathy who are medically unfit for surgery.
本研究的目的是评估将脉冲射频（PRF）应用于肩胛上神经对患有疼痛性肩袖撕裂性关节病且身体状况不适合手术的患者缓解疼痛的疗效。招募了12例因肩袖撕裂性关节病导致慢性肩部疼痛的患者。平均年龄为68岁（范围60 - 83岁）。使用PRF将肩胛上神经定位在肩胛切迹处。在消融前以及消融后3个月和6个月，使用牛津评分、Constant评分和视觉模拟量表（VAS）疼痛评分对患者进行评估。采用Friedman检验进行统计分析。10例患者的VAS评分（P = 0.24）和Constant评分（P = 0.005）有所改善，11例患者的牛津评分（P = 0.001）有所改善。在3至6个月之间，VAS评分出现恶化，表明随着时间推移益处开始减弱（P > 0.05）。我们得出结论，对于患有疼痛性终末期肩袖撕裂性关节病且身体状况不适合手术的患者，PRF可能是一种有用的治疗辅助手段。
