Abstract

Introduction: The sacroiliac joint (SIJ), despite limited mobility, plays a crucial role in load transfer and pelvic stability. As a true diarthrodial joint, it accounts for 15%–38% of low back pain cases. This study evaluated the clinical outcomes of radiofrequency ablation (RFA) for SIJ syndrome and examined predictors of treatment response.

Methods: We retrospectively analyzed 101 patients treated with intra-articular RFA between 2017 and 2020. Pain and function were assessed using the Visual Analog Scale (VAS), Oswestry disability index (ODI), and McNab criteria.

Results: The cohort (53.5% female, mean age 69.0 ± 14.2 years, BMI 28.18 ± 4.87) showed significant improvements in pain (VAS: 7.68 ± 1.4 to 2.6 ± 1.54 at 24 h, p < 0.001) and function (ODI: 57.5 ± 17.5 to 37.9 ± 16.97 at 12 months, p < 0.001). McNab scores improved from 2.36 ± 1.03 at 6 weeks to 3.32 ± 0.88 at 12 months (p < 0.001). Higher BMI was strongly associated with poorer outcomes (VAS r = 0.433–0.719, ODI r = 0.990, McNab r = –0.960 to –0.914; all p < 0.001). Prior spinal surgery affected short-term recovery but not long-term results.

Conclusion: Intra-articular RFA is an effective treatment for SIJ syndrome, offering sustained pain relief and functional improvement up to 12 months. High BMI negatively impacts outcomes, highlighting the value of adjunctive strategies like weight management and rehabilitation to enhance long-term success.

骶髂关节综合征射频消融治疗的预测因素、疗效和结果：一项回顾性研究

骶髂关节（SIJ）尽管活动受限，但在负荷转移和骨盆稳定中起着至关重要的作用。作为一个真正的腹泻关节，它占腰痛病例的15%-38%。本研究评估了射频消融（RFA）治疗SIJ综合征的临床结果，并检查了治疗反应的预测因素。方法：回顾性分析2017年至2020年间101例关节内RFA患者。采用视觉模拟量表（VAS）、Oswestry残疾指数（ODI）和McNab标准评估疼痛和功能。结果：该队列（53.5%女性，平均年龄69.0±14.2岁，BMI 28.18±4.87）疼痛（24 h时VAS: 7.68±1.4至2.6±1.54,p < 0.001）和功能（12个月时ODI: 57.5±17.5至37.9±16.97,p < 0.001）均有显著改善。McNab评分从6周时的2.36±1.03分改善至12个月时的3.32±0.88分（p < 0.001）。BMI越高，预后越差（VAS r = 0.433-0.719, ODI r = 0.990, McNab r = -0.960 - -0.914; p < 0.001）。既往脊柱手术影响短期恢复，但不影响长期结果。结论：关节内射频消融术是SIJ综合征的有效治疗方法，可提供长达12个月的持续疼痛缓解和功能改善。高BMI会对结果产生负面影响，强调了体重管理和康复等辅助策略对提高长期成功的价值。

期刊介绍： Acta Neurologica Scandinavica aims to publish manuscripts of a high scientific quality representing original clinical, diagnostic or experimental work in neuroscience. The journal''s scope is to act as an international forum for the dissemination of information advancing the science or practice of this subject area. Papers in English will be welcomed, especially those which bring new knowledge and observations from the application of therapies or techniques in the combating of a broad spectrum of neurological disease and neurodegenerative disorders. Relevant articles on the basic neurosciences will be published where they extend present understanding of such disorders. Priority will be given to review of topical subjects. Papers requiring rapid publication because of their significance and timeliness will be included as ''Clinical commentaries'' not exceeding two printed pages, as will ''Clinical commentaries'' of sufficient general interest. Debate within the speciality is encouraged in the form of ''Letters to the editor''. All submitted manuscripts falling within the overall scope of the journal will be assessed by suitably qualified referees.
