Main Article Content
Tóm tắt
Objective: Evaluation of some characteristics of shoulder joint injury lesions by 3.0 Tesla magnetic resonance arthrography (MRA). Subject and method: 39 patients with shoulder joint injuries underwent MRA 3.0 Tesla, cross-sectional descriptive study from February 2012 to August 2017. Result: There were 29 of patients who had rotator cuff lesions, 74.4% respectively. In which, there were 38.5% of patients who had a partial rotator cuff tear, supraspinatus partial thickness tear was the most common with 80.0%. The most common lesion in stage 3 with partial tear classification by Ellman and Habermeyer were 60.0% and 66.7% respectively, the difference between the classified by its is statistically significant with p<0.05 and kappa 0.86. The percent of patients with partial thickness bursal-side tear was the highest 53.3%, articular-side tear was 33.3%, interstitial tear was 13.3%, the difference between the classified by its is statistically significant with p<0.05. There were 25.6% of patients who had a complete tear of rotator cuffs tendon, supraspinatus full thickness tear was the most common with 70.0%, retraction in stage I, which is the lowest in classification by Patte and Baterman both were 20.0%, (kappa = 1.0). Supraspinatus tendon edema were the most common with 71.8%. The labrum lesion with type IV was the most common with 71.4%, type I, II, III were 3.6%, 7.1%, 17.9% respectively. Soft Bankart was the most common with 57.1%, osseus Bankart 28.6%, various Bankart 14.3%. Anatomical labrum varies was 12.8%. Hill-Sachs lesions 25.6%. SLAP lesions were 53.8%, in which, type II was the most common with 57.1%. Inferior glenohumeral ligament lesion was the most common with 45.0%, the difference between the number lesions of glenohumeral ligaments was statistically significant with p<0.05. Humeral head lesions were 71.8%, in which, osseus edema 100%. Conclusion: MRA was useful tools to gives a full and detailed assessment of the level and forms image lesions finding of shoulder join injuries.
