To compare magnetic resonance (MR) arthrography and arthroscopy as a means of assessing the severity of labral tear in anterior glenohumeral instability.
52 patients presenting with traumatic recurrent anterior shoulder instability were evaluated using MR arthrography; 30 shoulders with a labroligamentous lesion were treated with arthroscopic Bankart repair. Their MR arthrographic images were interpreted by 3 senior musculoskeletal radiologists, and a radiological diagnosis was reached by consensus. The sensitivity and positive predictive values of MR arthrography for detecting a labral tear were determined. Agreement between MR arthrography and arthroscopy in terms of the width and depth of the labral tear was analysed.
On arthroscopy, a labroligamentous lesion (Bankart lesion and its variants) was present in all the 30 shoulders. Agreement between the MR arthrography and arthroscopy in terms of the width and depth of the labral tears was good.
MR arthrography is an accurate means of assessing the severity of anterior labroligamentous lesions and yields a good correlation with arthroscopy.
比较磁共振（MR）关节造影和关节镜检查作为评估肩肱关节前侧不稳时盂唇撕裂严重程度的方法。
对52例创伤性复发性肩关节前侧不稳患者进行MR关节造影评估；对30例存在盂唇韧带损伤的肩关节进行关节镜下Bankart修复术治疗。3名资深肌肉骨骼放射科医生解读其MR关节造影图像，并通过协商达成放射学诊断。确定MR关节造影检测盂唇撕裂的敏感性和阳性预测值。分析MR关节造影和关节镜检查在盂唇撕裂宽度和深度方面的一致性。
关节镜检查显示，所有30例肩关节均存在盂唇韧带损伤（Bankart损伤及其变异型）。MR关节造影和关节镜检查在盂唇撕裂宽度和深度方面的一致性良好。
MR关节造影是评估前盂唇韧带损伤严重程度的准确方法，与关节镜检查具有良好的相关性。
