Pediatric exostosis is actually a very common phenomenon in children’s growth and development, especially in babies aged 0.5-2 years old, because the growth and development and nutritional status of children are now much better than those in the past, which also leads to his regular diet not keeping up with the growth rate, especially the intake of calcium is definitely far from enough. Therefore, without the usual routine calcium supplementation, children often have hair loss behind the occipital area, excessive sweating behind the occipital area, as well as noisy nights, easy to wake up, talking in their sleep, grinding their teeth, etc. There is also a common manifestation of rib cage exostosis. If you want to check the body, you need to lay down the patient and expose the front chest wall, you can feel a protrusion like two small planes at the junction of the chest and abdomen on both sides, which is typical of rib exostosis. Routine calcium supplementation is important. It is generally recommended that children within 6 months of age take vitamin AD supplements and get more sunlight, and during the period of 0.5-3 years of age routinely take calcium carbonate D3 granules and zinc gluconate oral solution, which are taken every other day, and it is best to do bone density measurement, and also consult a child health care practitioner and have regular medical checkups so that calcium supplementation is safer and more effective.
