What condition is characterized by an irregular sternum due to the fusion of connecting tissue of the ribs and/or breast-bone?

The condition characterized by an irregular sternum due to the fusion of connective tissue of the ribs and/or breast-bone is known as a deviated sternum. This condition can result in a misalignment of the sternum, which may not only affect the physical appearance of the chest but also have implications on respiratory function and overall health. The fusion of the tissues means that the ribs or breastbone do not articulate as they would normally, creating an abnormal structure that can vary in severity.

While conditions like Pectus Excavatum involve a depression of the sternum, a deviated sternum specifically refers to the misalignment or irregularity as a result of fusions or other structural abnormalities. This distinction is important for understanding different types of chest wall deformities. Other options, like Rib Fusion Syndrome, do not specifically describe the irregularity of the sternum itself and are not recognized medical terms for this particular condition.
