The sternum is a flat midline bone of the anterior thorax composed of the manubrium, body, and xiphoid process, which articulates with the clavicles and costal cartilages of the ribs; it functions to protect vital mediastinal structures including the heart and great vessels while serving as an important attachment site for the ribs, pectoral muscles, and other thoracic structures, with common pathologies including sternal fractures, costochondral injuries, osteomyelitis, and congenital deformities such as pectus excavatum and pectus carinatum.
