MRI对肩袖撕裂的诊断价值

Diagnostic value of MRI in rotator cuff tear

目的评价肩关节MRI对肩袖撕裂的诊断价值,并分析其影像特征及损伤机制。方法回顾性分析76例肩袖撕裂的MRI表现及临床症状。结果肩袖全层撕裂共25例。其中冈上肌腱撕裂23例,同时向冈下肌腱延伸5例,6例合并肩胛下肌腱部分撕裂,1例合并肱二头肌长头腱断裂,2例合并关节盂前上盂唇撕脱。肩袖部分撕裂共51例,全部发生在冈上肌腱。其中上表面侧11例,下表面侧32例,肌腱内部分撕裂8例。其中8例同时在上表面及下表面发生部分撕裂,3例同时合并下表面及肌腱内部分撕裂。结论肩关节MRI是评价肩袖撕裂比较有效的检查方法,为临床制定正确的治疗方案提供可靠的依据。

[Abstract] Objective To evaluate the diagnostic value of MRI in rotator cuff tear and to analyze imaging characteristics and mechanism underlying the damage. Methods MRI manifestations and clinical symptoms of 76 patients with rotator cuff tear were retrospectively analyzed. Results It was found that full thickness tears of the rotator cuff occurred in 25 ca- ses, the supraspinatus tendon tears in 23 cases and, at the same time, the infraspinatus tendon elongation in 5 cases. 6 ca- ses were combined with subscapularis tendon tear, 1 case with the long head of the biceps tendon rupture, and 2 cases with glenohumeral joint anterior glenoid labrum avulsion. Rotator cuff patrial tear appeared in all 51 cases. All occured in the supraspinatus tendon, of which lloccured in the upper surface side, 32 in the lower surface side, 8 within the tendon par- tial tear. Of these, 8 exhibited the partial tear both in the upper surface and a lower surface and 3 presented with partial tear in lower surface and within the tendon simultaneously. Conclusion Shoulder MRI is an effective screening method for evaluating rotator cuff tear, which can provide a reliable basis for setting the right treatment in clinic.
