OBJECTIVES Percutaneous radiofrequency is an established method for treatment of chronic low back pain of intervertebral facet etiology. Endoscopic techniques have the advantage of visualization of the facet joint and the dorsal medial ramus and thus allow for more accurate denervation. It was thus hypothesized that pain reduction is vaster and longer enduring. PATIENTS AND METHODS A total of 98 consecutive patients that underwent endoscopic facet joint denervation (EFJD) were included in this study. Prior to intervention and for follow-up, patients were asked to complete VASpain, ODI, COMI and EQ5D questionnaires. RESULTS VASpain was reduced significantly (EFJD: p < 0.001) at last follow-up. Values for ODI, COMI and EQ5D showed significant improvements towards subjective well-being at last follow-up. CONCLUSION EFJD is a promising technique for the treatment of facet joint syndrome caused CLBP as it contributes to sustaining significant pain reduction and improvement of subjective quality of life parameters.

内窥镜小关节去神经支配治疗慢性腰痛

目的 经皮射频是治疗椎间小关节慢性腰痛的一种既定方法。内窥镜技术具有小关节和背内侧支可视化的优点，因此可以更准确地去除神经支配。因此假设疼痛减轻幅度更大且持续时间更长。患者和方法 本研究共包括 98 名连续接受内窥镜小关节去神经支配术 (EFJD) 的患者。在干预和随访之前，要求患者完成 VASpain、ODI、COMI 和 EQ5D 问卷。结果 VASpain 在最后一次随访时显着降低（EFJD：p < 0.001）。ODI、COMI 和 EQ5D 的值在最后一次随访时显示出对主观幸福感的显着改善。
