Aims: To compare Ultra Sonography (USG) with Magnetic Resonance Image (MRI) in evaluation of lesions causing impairment of mobility of the shoulder joint.
Method and Materials: This study was a cross-sectional observational study. Sonographic examination of shoulder was done using a linear high-frequency probe (7.5-15 MHz) on Siemens machine and MRI evaluation was performed on 3T Siemens Skyra machine. Data was analyzed using standard statistical methods and results were compared with Arthroscopy where possible. According inclusion criteria the patients of all age groups presenting with symptoms of shoulder pain or restricted movement referred from department of orthopaedics were studied.
Findings: Fifty patients were included in the study. Sensitivity and specificity of USG in comparison with MRI for diagnosing supraspinatus, subscapularis, infraspinatus and long head of biceps tendon pathologies in our study were 95.4% and 100%, 66.6% and 100%, 60% and 100%, 80% and 100% respectively. Sensitivity and specificity of USG for detecting AC joint arthropathy were 88.2% and 100% respectively in our study. The Sensitivity and specificity of USG were 82.7% and 100% respectively in detecting Subacromial Subdeltoid bursitis (SASD) bursitis, which were similar to as in other studies in literature.
Conclusion: This study revealed that USG has a good sensitivity, specificity and diagnostic accuracy in diagnosing rotator cuff tendon tears and tendinosis as well as for diagnosis of Acromioclavicular (AC) joint arthroplasty. Moreover, it is a non-invasive technique, readily available and cost effective. MRI is best modality for diagnosing labro-ligamentous pathologies at the shoulder.
