OBJECTIVE
To assess the effectiveness of repeated radiofrequency neurotomy (RFN) on pain, disability, and treatment effect duration.
PATIENTS
One hundred-four patients who underwent repeat RFN for chronic neck or back pain were prospectively followed using a Pain Disability Questionnaire-Spine (PDQ-S). Complete data sets were available for 73, 73, and 36 patients for the 1st, 2nd, and 3rd RFN, respectively.
RESULTS
Pain intensity, pain frequency, and patient-specific disability measures were significantly improved post-initial, second, and third RFN. Moreover, there was no statistically significant difference among the PDQ-S scores post-RFN 1, 2, and 3. There was no statistical significance between the duration of pain relief post-RFN 1 and pain relief post-RFD 2.
CONCLUSION
Repeated cervical and lumbar RFN reduces pain and disability with equal effectiveness for approximately 10 months in patients with facetogenic chronic neck and back pain.
目的
评估重复射频神经切断术（RFN）治疗慢性颈痛或腰痛的有效性，包括疼痛、残疾和治疗效果持续时间。
患者
104 例接受重复 RFN 治疗慢性颈痛或腰痛的患者前瞻性地使用脊柱疼痛残疾问卷（PDQ-S）进行随访。分别有 73、73 和 36 例患者可获得第 1、2 和 3 次 RFN 的完整数据集。
结果
初始、第二次和第三次 RFN 后疼痛强度、疼痛频率和患者特定残疾指标均显著改善。此外，RFN 后第 1、2 和 3 次 PDQ-S 评分之间无统计学差异。RFN 后 1 缓解疼痛的持续时间与 RFN 后 2 缓解疼痛的持续时间之间无统计学意义。
结论
在 facetogenic 慢性颈痛和腰痛患者中，重复颈腰椎 RFN 可减轻疼痛和残疾，约 10 个月内疗效相当。
