Abstract:
PURPOSE: The purpose of this study was to evaluate the accuracy and the usefulness of MRI in patients with shoulder injuries. MATERIALS AND METHODS: The sensitivity and the accuracy of MRI in the diagnosis of various lesion were evaluated in 20 patients with shoulder injuries. RESULTS: MRI enabled Bankart lesions and SLAP lesions to be accurately predicted with 100% sensitivity and 90% accuracy in both. However, for types of SLAP lesions, the sensitivity and the accuracy were 60% and 70%, respectively, and for full-thickness or partial-thickness tear of rotator cuff, the sensitivity and the accuracy were 75% in both. MRI was also effective at predicting rotator cuff tear with 100% sensitivity and 95% accuracy. Sensitivity and accuracy for the diagnosis of Hill-Sachs lesion were 91.7% and 90%, respectively. For all lesions except Hill-Sachs lesion, the negative prediction value was higher than the positive prediction value, which means MRI overestimated the lesions. CONCLUSION: MRI was accurate and useful in the prediction of prediction of rotator cuff tear, labral tear and Hill-Sachs lesions. However, for the identification of full-thickness or partial-thickness tear of rotator cuff, and types of SLAP lesions, it was less accurate and less useful.
