Whether the protrusion of the bone of the sternal stalk is normal or not depends on the specific situation of the patient. First, if a patient suffers a serious impact injury to the chest, accompanied by the protrusion of the bone of the sternal stalk and obvious local swelling and pain, it is necessary to consider whether a sternal fracture has occurred, and it is necessary to improve CT or X-ray examination as soon as possible. If the sternum is found to have multiple fractures, which is not a normal phenomenon, the patient needs to go to the hospital as soon as possible and perform surgery in a timely manner, and strengthen the anti-infection, analgesic and edema treatment after surgery in order to control the local swelling and pain symptoms more quickly. Second, for patients with a thin physique, the protrusion of the sternal stalk of the bone can be caused by the absence of more muscles in the chest. In this case, if the patient does not have obvious local swelling and pain, this is caused by individual development, which is a normal physiological phenomenon and does not require special treatment and will not cause serious clinical complications.
