Generally, the causes of this deformity are 1. In the fetal or infant period, the development of sternum, spine and ribs is unbalanced, leading to chest deformity. 2. After babies are born, they can't get enough nutrition and suffer from some malnutrition diseases, such as rickets in children, which will affect the development of sternum for a long time and cause thoracic deformity. 3. Secondary thoracic diseases. For example, some congenital heart diseases, the enlarged heart compresses the chest wall, forming a chicken breast deformity.
