Clinically, there are not many diseases caused by a bulging sternocostal process because the structure of the process is relatively simple, so there is no disease that can cause it to bulge. If the patient is thin, the sternal eminence may look more obvious, so this is a normal phenomenon. If there are no other accompanying symptoms, it is recommended that the patient can observe it first, perhaps because it is caused by a thin or special figure, there are no other accompanying symptoms and there is no need to go to the hospital. The sternal saber is generally a relatively uncommon cause of disease, saber syndrome is a benign syndrome of arthrosis, a clinical disease caused by sterile inflammation of the saber tissue.
