ABSTRACT
Shoulder pin and dislocation usually occur more frequent in young athletes, this study was carried out to assess the role of MRI and US in evaluation of chronic shoulder pain and instability of the shoulder joint. 43 patients complaining of chrome shoulder pain and some of them complaining shoulder instability were examined by MRI, MR arthrography and high resolution ultrasonography. All patients had anterior glenohumeral dislocation [41 males, 95.3% and 2 females, 4.7%]. On MR arthrography, the antero-inferior labrum was torn in 35 case "81.4%", the anterior labrum was torn in 4 cases "9.3%" and attenuated in 4 cases "9.3%", while on conventional MRI the percentages were 44.3% [19 case], 4.7% [2 cases] and 4.7% [2 cases] respectively. US depicted full anterior labral tear in 39 of 43 patients. Sensitivity was 92%, and accuracy was 92%. MR arthrography has been proved to increase the sensitivity and accuracy of MRJ for detecting labor-ligamentous complex and rotator cuff tendon abnormalities. Accuracy of US in depiction of labral tears and associated fractures indicates that US can provide a useful information in patients with anterior shoulder instability
