An X-ray (radiography) is a simple test in which an X-ray beam (a form of electromagnetic radiation) is passed through the shoulder to create a two-dimensional picture of the bones that form the joint. It can help your doctor view the inside of your shoulder without making an incision. The shoulder X-ray helps the doctor to detect if there are any joint space, bone spurs, or fractures. The doctor may order an X-ray to examine an area where you are experiencing pain or discomfort.
