Infantile rib eversion is a common disease in infancy. Because the two ribs at the bottom of the human sternum are not connected with the sternum, and infants mainly breathe in the abdomen, the breathing mobility is large, and rib eversion is more common in infancy. Its occurrence and development may be related to vitamin D deficiency, heredity, improper nursing and other factors. Vitamin D deficiency: Vitamin D is closely related to human skeletal development. Due to the lack of vitamin D, calcium and phosphorus metabolism disorder can occur in children, which leads to incomplete calcification of bones, which leads to valgus of ribs and eventually leads to skeletal deformity. Heredity: If there are rib eversion patients in the family, the chances of rib eversion will also increase. Therefore, genetic factors may also be one of the reasons for the baby's rib eversion. Improper nursing: If the baby's family members take improper daily care, such as tying the baby's belt above the baby's ribs, or tying the baby's belt too high and too tight, it will lead to the symptoms of one or both ribs everting. In this case, most babies' rib eversion can be quickly corrected by adjusting nursing methods.
Basically every child has a little rib eversion. This physiological feature is not calcium deficiency, but because the baby's bones are soft and the breathing range is relatively large, so the bottom of the ribs often expands outward with breathing, forming rib eversion. In addition, due to the rigidity of the infant diaphragm (located inside the penultimate intercostal rib), there will be different degrees of rib valgus. When the child is lying, sitting or standing, the rib valgus will be more obvious. However, parents need not worry too much. The phenomenon of rib eversion will gradually disappear when the baby is 2 to 3 years old.
