The aim of the study was to assess the accuracy of ultrasound-guided needle placement for sacroiliac joint injections.
Institutional review board approval was gained for a prospective cohort study of 50 patients (N = 50). Study patients who were referred for sacroiliac joint injections for sacroiliac joint mediate pain and met inclusion/exclusion criteria were enrolled in the study. Each patient underwent needle placement with ultrasound guidance in the procedure suite. After the needle was placed with the ultrasound guidance, fluoroscopy was used to confirm correct placement via contrast injection confirming a sacroiliac joint arthrogram. The arthrogram was confirmed via the performing physician and radiologist.
The placement of the needle with ultrasound guidance into the sacroiliac joint was confirmed successful in 96% (48/50) patients by fluoroscopic arthrogram. The two patients with unsuccessful arthrograms after initial placement of the needle with ultrasound were morbidly obese. There was intravascular uptake during the arthrogram of one patient who had a successful arthrogram.
Ultrasound-guided injection of the sacroiliac joint is successful and accurate upon confirmation of fluoroscopic arthrogram and should be used as an imaging modality for needle guidance.
本研究旨在评估超声引导下骶髂关节注射的准确性。
本前瞻性队列研究纳入了 50 名患者（N=50），均经机构审查委员会批准。研究患者因骶髂关节中轴性疼痛而接受骶髂关节注射，并符合纳入/排除标准。每位患者均在介入治疗室内接受超声引导下的针置放。在超声引导下将针放置到位后，通过对比剂注射透视确认正确的位置，以确认骶髂关节关节造影。关节造影由实施医生和放射科医生确认。
通过透视关节造影，96%（48/50）的患者的超声引导下的针置放被确认成功。最初超声引导下针置放后关节造影不成功的 2 名患者为病态肥胖。1 名关节造影成功的患者在关节造影期间出现了血管内摄取。
超声引导下的骶髂关节注射在透视关节造影确认后是成功且准确的，应作为一种用于引导针的影像学方法。
