BACKGROUND Chronic hip pain is one of the most common and difficult-to-treat causes of disability. Our study’s primary aim was to investigate the effects of ultrasound and fluoroscopy-guided radiofrequency thermocoagulation of the femoral and obturator nerve articular branches on chronic hip pain, and the secondary aim was to determine its effects on hip function and quality of life. METHODS Fifty-three patients with hip pain lasting more than three months were enrolled in the study. VPS scale and WOMAC, SF-12 questionnaires were applied to the patients before and in the first, third, and sixth months following the procedure. RESULTS Of the patients, 60.4% were female, and 39.6% were male. Hip pain was caused by osteoarthritis in 77.1%, postoperative hip pain in 12.5%, malignancy in 8.3%, and avascular necrosis in 2.1%. The VPS scores were 8.9 ± 1.1 (mean±SD) in the baseline period, 2.4 ± 2.5 in the first postoperative week, 3.8 ± 2.5 in the first month, 5.1 ± 2.8 in the third month, and 5.8 ± 2.7 in the sixth month, with a significant decrease in VPS score (p < 0.001). One patient developed a motor deficit that improved spontaneously. CONCLUSIONS We concluded that radiofrequency thermocoagulation application to the articular branches of the femoral and obturator nerves provides pain relief, hip function improvement, and better quality of life (better physical component scores but no improvement in mental component scores in SF-12) for up to 6 months in chronic hip pain.

股骨和闭孔神经关节支的常规射频热凝术对慢性髋部疼痛的影响：一项前瞻性临床研究

背景技术慢性髋部疼痛是最常见且难以治疗的残疾原因之一。我们研究的主要目的是研究超声和透视引导下股骨和闭孔神经关节支射频热凝术对慢性髋部疼痛的影响，次要目的是确定其对髋部功能和生活质量的影响。方法 53 名髋部疼痛持续超过三个月的患者被纳入该研究。在手术前以及术后第一、第三和六个月内对患者进行 VPS 量表和 WOMAC、SF-12 问卷调查。结果 患者中女性占60.4%，男性占39.6%。髋部疼痛由骨关节炎引起，占77.1%，术后髋部疼痛占12.5%，恶性肿瘤占8.3%，股骨头缺血性坏死占2.1%。基线期 VPS 评分为 8.9 ± 1.1（平均值±标准差），术后第一周为 2.4 ± 2.5，第一个月为 3.8 ± 2.5，第三个月为 5.1 ± 2.8，第六个月为 5.8 ± 2.7 ，VPS 分数显着下降 (p < 0.001)。一名患者出现运动缺陷，但随后自行改善。结论 我们的结论是，射频热凝应用于股骨和闭孔神经的关节支可以缓解疼痛，改善髋部功能，并提高生活质量（SF-12 中身体成分评分更好，但精神成分评分没有改善）长达慢性髋部疼痛 6 个月。
