Background: The advantages of USG include low cost,
accessibility, and capability for real-time high-resolution imaging
that enables a dynamic assessment. Dynamic examination of
shoulder can be carried out in multiple planes and areas of concern
can be focused promptly to make a diagnosis. The aim of this
study was to evaluate the role of ultrasound in diagnosis of
common shoulder joint lesions. Methods: Our cross-sectional
study was carried on 36 patients who were referred from outpatient
clinics to the radiology department with shoulder complain. The
first assessment was done by US and finally confirmed by MRI as
a gold standard. Results: US predicted patients with SSP
tendinopathy, with accuracy, sensitivity, specificity, PPV and NPV
was 55.6%,100%, 72.7%, 70% and 100% respectively (p < 0.001).
US was able to predict patients with SSP partial tear, with
accuracy, sensitivity, specificity, PPV and NPV was 88.9%,80%,
100%, 100% and 80% respectively (p < 0.001). US was able to predict patients with SSP full
thickness tear, with accuracy, sensitivity, specificity, PPV and NPV was 100%,100%, 100%,
100% and 100% respectively (p < 0.001). US was able to predict patients with Biceps long head
tenosynovitis with accuracy, sensitivity, specificity, PPV and NPV was 94.4%,100%, 91.7%,
85.7% and 100% respectively (p < 0.001). Conclusion: USG can be used as an initial line of
investigation for evaluation of all patients who are clinically suspected to have rotator cuff
