Recent MRI Study of Acute Shoulder Trauma

Abstract Background: Magnetic Resonance Imaging (MRI) is considered a reliable technique for the evaluation of the different causes of shoulder pain. The anatomy of the shoulder is unique, with amazing flexibility and range of motion. Many causes of painful shoulder syndrome are there; shoulder impingement come on top of the list, large number of factors could cause shoulder impingement syndrome. Two major categories were identified: structural factors and functional factors. Aim of Study: Is to review an accurate and highly sensitive diagnostic evaluation of frequently encountered acute traumas of shoulder joint in athletes. Patients and Methods: 40 patients shared in this study, patients with symptoms of painful shoulder and limited movements of their shoulders to Sport Injuries Orthopedic Clinic. Informed oral consent explaining the procedure details was obtained from all patients prior to inclusion in the study. The privacy of participants and confidentiality of data were guaranteed during the various phases of the study. All patients underwent history taking, clinical provisional diagnosis, radiological investigations in the form of Magnetic Resonance Imaging. Descriptive statistics were done for quantitative data as minimum & maximum of the range as well as mean ± SD (standard deviation). Image analysis was conducted by two radiology fellows, each with an experience in interpretation Musculoskeletal (MSK) MR images, both were blinded to the results and reports and independently evaluated the MR images. Results: Effusion, Bankart, Hillsachs and Rotator cuff tear were the most frequent MRI findings. Majority of cases had two-three findings. No significant difference according to mode of trauma regarding age and sex. Weight lifting was significantly the most frequent regarding traction mode of trauma; team sport was significantly the most frequent regard-ing direct impact mode of trauma, while weight lifting and team sport had non-significant difference regarding Fall on Out Stretched Hand (FOOSH). Conclusion: Careful history taking of the patient like type of the sport, mode of trauma and severity of trauma is a very important tool that can help the radiologist to predict different lesions could be found in the study of each patient and finally reach an accurate diagnosis in an easier way and saving lots of time doing so.
