Abstract
Objective To develop magnetic resonance imaging (MRI) protocol for assessing acromioclavicular joint (ACJ) in patients with dislocation of the acromial end of the clavicle, grading severity of injury after trauma and evaluating outcome of surgical treatment. Material and methods MRI was performed for 15 patients with ACJ injury before and after treatment. Based on MRI findings patients were subdivided into three groups depending on the degree of ACJ injury. Results In addition to radiography MRI yields important findings on a complex of pathological changes in ligaments, muscles and subcutaneous tissues. The imaging showed edema and a partial-thickness injury to the trapezius muscle (n=7), swollen subcutaneous tissue (n=15), a glenoid labral tear (n=4) and a rotator cuff injury (n=7). Conclusion MRI has been particularly effective in characterizing ACJ injuries and associated changes in the bone and soft tissues. The capabilities of MRI in visualization of soft tissues have made this imaging modality invaluable in the assessment of outcomes of the dislocation of the acromial end of the clavicle.
