The treatment of protruding sternum is different for different age groups. For protruding sternum in infants and children, it may be caused by calcium deficiency and requires active hospitalization to improve the calcium ion level check in the body. If there is a calcium ion deficiency, calcium should be supplemented, including calcium carbonate D3 tablets, calcium gluconate oral solution, and also intravenous calcium gluconate injection, as well as more sunshine, more milk, and appropriate physical exercise, most of them can be well recovered. For adult patients with protruding sternum, most of the cases may be caused by developmental abnormalities, and generally do not have obvious symptoms and do not require special treatment. If there is local pain or discomfort, it is necessary to improve the examination to clarify whether there is scoliosis or some internal diseases, and if there are indications for surgery, active surgical treatment. Sternal protrusion may also be caused by a sternal fracture, which may result in a bone scab to promote healing of the fracture, and may also lead to local sternal protrusion, which also does not require treatment.
