Stress radiographs for evaluating acromioclavicular joint separations in an active-duty patient population: What have we learned?

This study identified substantial practice variation amongst military surgeons treating a relatively homogenous population with AC joint separations, reflective of a lack of definitive evidence to guide diagnosis and treatment. Overall, nonoperative management is the preferred initial approach for Type III injuries and operative treatment is the preferred initial approach for Type V injuries. The diagnostic evaluation varied across the surgeon cohort, but 87% elected against the use of weighted stress radiographs for the evaluation of AC joint separations, with only 10% relying upon them to dictate their recommended treatment. Future research identifying optimal diagnosis and treatment of AC joint separations is needed.
