■用于SIJ的超声(US)引导RFA技术,利用双极射频套管沿外侧骶骨(LSC)放置,已在解剖学研究中提出。这项研究评估了疼痛强度的变化,功能和生活质量遵循这种技术。
■两组疼痛缓解≥50%的患者(一个FL-和一个US-指导)被纳入研究。使用沿LSC放置的两个多色RF套管,对顺序双极病变进行了US引导的SIJRFA。疼痛,残疾,生活质量问卷-脊柱(PDQQ-S),其中包括疼痛强度的11分(0-10)数字评定量表(NRS),在RFA之前完成,RFA后2、6、9、12和16个月。在RFA后2个月的结果比较了美国指导和FL指导的SIJRFA与先前FL指导的SIJRFA的参与者。
■包括31例患者。在美国指导的SIJRFA后9个月内观察到疼痛强度的统计学显着下降(基线NRS:平均值=6.8SD=1.6,95CI[6.169,7.347];9个月:平均值=4.8,SD=2.6,95CI[3.891,5.786];p=0.0005),PDQQ-S长达12个月。在9个月时,有48.4%的参与者在NRS上观察到临床上显着的疼痛强度降低≥2分。11名参与者先前接受过FL指导的SIJRFA;RFA后2个月,美国和FL指导的SIJRFA之间的疼痛强度或PDQQ-S评分无统计学差异。
■初步结果表明,可以使用美国指南进行SIJRFA。需要进一步研究以确定有效性。
UNASSIGNED: An ultrasound (US) guided RFA technique for the SIJ, utilizing bipolar RF cannula placements along the lateral sacral crest (LSC), has been proposed in anatomical studies. This study evaluated changes in pain intensity, function and quality of life following this technique.
UNASSIGNED: Patients achieving ≥50% pain relief on two blocks (one FL- and one US-guided) were included. US-guided SIJ RFA was performed with sequential bipolar lesions using two multitined RF cannulae placed along the LSC. The Pain, Disability, Quality of Life Questionnaire-Spine (PDQQ-S), which includes an 11-point (0-10) numeric rating scale (NRS) for pain intensity, was completed pre-RFA, and 2, 6, 9, 12 and 16 months post-RFA. Outcomes at 2 months post-RFA were compared between US-guided and FL-guided SIJ RFA in participants with previous FL-guided SIJ RFA.
UNASSIGNED: 31 patients were included. Statistically significant decreases in pain intensity were observed up to 9 months after US-guided SIJ RFA (Baseline NRS: mean = 6.8 SD = 1.6, 95%CI [6.169, 7.347]; 9 month: mean = 4.8, SD = 2.6, 95%CI [3.891, 5.786]; p = 0.0005), and up to 12 months for PDQQ-S. A clinically significant ≥2 point reduction in pain intensity on the NRS was seen in 48.4% of participants at 9 months. 11 participants had previous FL-guided SIJ RFA; no statistically significant differences were found in pain intensity or PDQQ-S scores between US- and FL-guided SIJ RFA 2-months post-RFA.
UNASSIGNED: Preliminary results suggest that SIJ RFA could be performed using US guidance. Further study is required to establish effectiveness.
