Rickets is due to vitamin D deficiency and is reversible in the early stages. However, if skeletal deformities occur in the later stages, they often have sequelae. Rickets is a systemic chronic nutritional disease, caused by a combination of insufficient vitamin D intake, excessive growth and development, and disease, etc. Early in the child’s life, symptoms such as occipital baldness, nocturnal alarms, excessive sweating, irritability, etc., may occur, and with the development of the disease, there may be cranial softness, square skulls, bracelets of the hands and feet, ribs beading disorder and other skeletal changes. For children in the early stages of the disease, supplementation with vitamin D, calcium gluconate and other medications under the direction of a doctor may result in a cure. However, for patients who have had the condition for a longer period of time and have developed skeletal deformities or changes, they may often be left with sequelae, but some of the skeletal deformities can be improved by surgical correction.
