Hip osteoarthritis (OA) has a prevalence of 2.9% in Portugal and is a related cause of pain and disability. A sufficient number of patients report these symptoms even after total hip arthroplasty (THA), while others are contraindicated to such surgery and suffer from uncontrolled pain. Percutaneous denervation of hip nerve branches using radiofrequency ablation (RFA) has emerged as a powerful therapeutic avenue to consider for patients with chronic hip pain.
Between January 2020 and March 2021, 26 patients with chronic hip pain received ultrasound-guided RFA with a pericapsular nerve group (PENG) block technique adaptation. Patients suffering from chronic hip pain for more than three months with radiographic evidence of osteoarthritis were included. A numeric rating scale (NRS) and pain medication reduction were defined as outcome variables assessed before treatment and at three-, six-, nine-, and 12-month follow-ups.
All selected patients underwent the procedure. All the patients had hip osteoarthritis. Twelve-month follow-up data revealed a statistically significant decrease in the numeric rating scale. The mean NRS for pain was 2 after the procedure. Over 75% of patients reported >50% pain relief during the follow-up and 85% reduced pain medication consumption. No side effects were reported.
Hip sensory articular branch RFA is a treatment option with interesting outcomes for chronic hip pain, as demonstrated by our study.
髋关节骨关节炎（OA）在葡萄牙的患病率为2.9%，是疼痛和残疾的相关原因。即使在全髋关节置换术（THA）后，仍有相当数量的患者报告这些症状，而其他患者则因手术禁忌而遭受无法控制的疼痛。使用射频消融（RFA）对髋关节神经分支进行经皮去神经支配已成为慢性髋部疼痛患者可考虑的一种有效治疗途径。
2020年1月至2021年3月期间，26例慢性髋部疼痛患者接受了超声引导下的RFA，并采用了关节周围神经组（PENG）阻滞技术改良。纳入患有慢性髋部疼痛超过三个月且有骨关节炎影像学证据的患者。将数字评分量表（NRS）和疼痛药物减少量定义为治疗前以及随访3个月、6个月、9个月和12个月时评估的结果变量。
所有选定患者均接受了该手术。所有患者均患有髋关节骨关节炎。12个月的随访数据显示数字评分量表有统计学意义的下降。术后疼痛的平均NRS为2。超过75%的患者在随访期间报告疼痛缓解>50%，85%的患者减少了止痛药物的使用。未报告有副作用。
正如我们的研究所表明的，髋关节感觉关节支RFA是一种治疗慢性髋部疼痛且疗效有趣的治疗选择。
