Aim: The aim of this study is to evaluate role of magnetic resonance imaging and ultrasound in diagnosis of traumatic shoulder injuries. Patients and methods: Fifty patients who had one or more of post traumatic shoulder dislocation, pain or limitation of the affected shoulder joint movements were examined by gray scale ultrasound and conventional magnetic resonance imaging. Results: 18 cases were diagnosed as supraspinatus tears (11 partial tear and 7 complete tear). 8 cases were diagnosed as supraspinatus tendinosis. Four cases were diagnosed as acromioclavicular joint lesions 2 of them were diagnosed as acromioclavicular joint separation and 2 cases were diagnosed as acromioclavicular joint osteoarthritis and all of cases with acromioclavicular joint lesions were associated with impingement syndrome. 11 cases were diagnosed as Hill Sach`s fracture; 5 of them were associated with Bankart lesion. Two cases were diagnosed as biceps tendon instability. Four cases were diagnosed as biceps tenosynovitis. Conclusion: ultrasound should be increasingly used as the first-line imaging modality in the assessment of traumatic shoulder lesions. Further magnetic resonance imaging is needed in order to evaluate the joint in more detailed manner
