ABSTRACT
Background: Stability to the shoulder joint which has great range of motility, is provided by the rotator cuff, the coraco-acromial arch and the glenoid labrum along with the capsule and glenohumeral ligaments. The common disorders involving the rotator cuff tendons include impingement, tendinopathies and tears. Magnetic Resonance Imaging (MRI) has good spatial resolution for identifying tendon edema and tears in the rotator cuff. Aim and objectives: To describe the MRI characteristics of rotator cuff pathologies. To describe the rotator cuff pathologies in terms of age, gender, symptomatology and predisposing factors among the study population. Materials and methods: The study was performed in the Department of Radiodiagnosis, NRI General Hospital, Chinakakani, Guntur from September 2015 to August 2017 and comprises of 100 patients with suspected rotator cuff pathologies who were referred for MRI shoulder. Results: The age distribution of patients with rotator cuff abnormalities was in the range of 21 and 74 years. The most commonly affected was supraspinatus tendon followed by subscapularis and infraspinatus tendons. Among the rotator cuff abnormalities the frequently encountered finding was tendinosis followed by partial tears. Conclusion: Magnetic Resonance Imaging is very useful in depicting rotator cuff disease in patients with painful, weak or stiff shoulder for prompt and accurate diagnosis.
