Patient's question:
How should the baby be treatedDoctor's answer:
It is due to poor calcium absorption caused by a lack of vitamin D, leading to calcification at the bone sites. Square head is more common in infants aged 6-8 months, where the central part of the frontal bone and parietal bone becomes thickened, appearing like a box when viewed from above, hence the name "square head." Pigeon chest refers to chest deformity in children around 1 year old due to calcium deficiency and lack of vitamin D, where the sternum and adjacent cartilage protrude forward, accompanied by the prominence of the costochondral junctions, resembling a string of beads.Advice: Chest deformity caused by a lack of vitamin D, with the sternum and adjacent cartilage protruding forward.
