One method for performing effective shoulder arthrography with a fluoroscopically guided anterior approach is described. The technique can ensure success while injury to the cartilaginous labrum is avoided, which is essential when arthrography is performed in conjunction with magnetic resonance (MR) imaging. The key features of the technique include supine positioning of the patient with the shoulder in external rotation, marking the skin just lateral to the humeral head cortex, inserting the needle perpendicular to the fluoroscopy beam, testing the injection with an anesthetic agent, and confirming intraarticular needle placement with iodinated contrast material. The procedure can be followed by an injection of dilute gadolinium solution for subsequent MR imaging. Proper patient and needle positioning as well as accurate confirmation of intraarticular needle placement are critical to a successful and atraumatic shoulder arthrographic examination.
本文描述了一种在荧光透视引导下经前路进行有效肩关节造影的方法。该技术可确保成功，同时避免损伤软骨盂唇，这在肩关节造影与磁共振成像（MR）联合进行时至关重要。该技术的关键要点包括患者仰卧，肩部外旋，在肱骨头皮质外侧标记皮肤，将针垂直于透视束插入，用麻醉剂测试注射情况，并用碘化造影剂确认针在关节内的位置。该操作之后可注射稀释的钆溶液以便后续进行MR成像。正确的患者和针的定位以及准确确认针在关节内的位置对于成功且无创的肩关节造影检查至关重要。
