Sixty-two patients with anterior shoulder dislocations were examined by magnetic resonance imaging (MRI). After a primary dislocation, 30 patients showed 23 (77%) tears of the glenoid labrum, 13 (45%) anterior-inferior separation of the capsula, 24 (83%) Hill-Sachs lesions, 6 fractures of the greater tuberosity and 4 glenoid rim fractures. Thirty-two patients with recurrent shoulder dislocation had 14 (44%) tears and 15 (47%) defects of the glenoid labrum, 16 (50%) anterior-inferior separation of the capsula, 28 (88%) Hill-Sachs lesions and 3 glenoid rim fractures. MRI permits complete non-invasive documentation of glenohumeral instability if joint effusion is present. In the absence of joint effusion, diagnostic accuracy can be improved by application of a contrast medium.
62例肩关节前脱位患者接受了磁共振成像（MRI）检查。初次脱位后，30例患者出现23处（77%）肩胛盂唇撕裂、13处（45%）关节囊前下分离、24处（83%）希尔-萨克斯损伤、6处大结节骨折和4处肩胛盂边缘骨折。32例复发性肩关节脱位患者有14处（44%）肩胛盂唇撕裂和15处（47%）肩胛盂唇缺损、16处（50%）关节囊前下分离、28处（88%）希尔-萨克斯损伤和3处肩胛盂边缘骨折。如果存在关节积液，MRI可对盂肱关节不稳进行完整的非侵入性记录。在无关节积液的情况下，应用造影剂可提高诊断准确性。
