Fluoroscopic injection through the rotator cuff interval (RCI) is a common technique for diagnostic arthrography and therapeutic intervention. Ultrasound approaches through the RCI have been less commonly studied, but there is a growing body of literature.
The purpose of this study was to present a standardized technique of ultrasound-guided injection into the glenohumeral joint utilizing the RCI in magnetic resonance imaging (MRI) arthrography (MRA) and to report one medical group's experience with the technique.
A retrospective chart review of all ultrasound-guided injections into the glenohumeral joint utilizing the RCI was performed from July 1, 2014 through June 1, 2021. Data were compiled for age, gender, body mass index (BMI), and prior surgery on the shoulder. The primary endpoint was successful administration of intra-articular dilute gadolinium contrast adequate for radiologic interpretation. A total of 487 injections into the glenohumeral joint via the RCI were performed. One hundred and fifty-five patients had previous shoulder surgery, with the remainder naive to intervention.
The success rate of injections into the glenohumeral joint was 99.4 %, with only three injections considered unsuccessful. The three unsuccessful injections did not succeed because of a lack of intra-articular contrast media present. This success rate is impressive and promising, particularly when considering that 155 of the patients had previous surgery, which could potentially cause complications, and because these injections were performed over a long period of 7 years.
Accessing the RCI under ultrasound guidance is a very successful technique for injection within the glenohumeral joint.
经肩袖间隔（RCI）行荧光透视注射是诊断性关节造影和治疗性介入的常用技术。经 RCI 的超声入路研究较少，但文献越来越多。
本研究旨在介绍一种在磁共振成像（MRI）关节造影（MRA）中经 RCI 行超声引导关节内注射的标准化技术，并报告一个医疗组应用该技术的经验。
对 2014 年 7 月 1 日至 2021 年 6 月 1 日期间所有经 RCI 行超声引导关节内注射的病例进行回顾性图表审查。收集年龄、性别、体重指数（BMI）和肩部既往手术的数据。主要终点是成功注射关节内稀释钆造影剂，以便进行影像学解读。共对 487 例经 RCI 行肩关节注射。155 例患者有肩部手术史，其余患者为初次接受介入治疗。
关节内注射的成功率为 99.4%，只有 3 次注射被认为不成功。这 3 次不成功的注射未能成功，因为关节内缺乏造影剂。这一成功率令人印象深刻，很有前途，特别是考虑到 155 例患者有既往手术史，这可能会导致并发症，而且这些注射是在 7 年的时间内进行的。
在超声引导下进入 RCI 是一种非常成功的肩关节内注射技术。
