Rickets is short for a series of diseases caused by vitamin D deficiency, children with this disease can have the following symptoms: a. Psychoneurological symptoms: sweating, night terrors, crying, etc. Sweating is not related to the climate due to sweat stimulation children often rub the occipital area to form occipital baldness or ring-shaped hair loss; b. Bone iliac manifestations: 1, head: (1) cranial softening: early manifestations of rickets are mostly seen in 3-6 months infants; (2) cranial deformities (2) head deformity: “square skull” “saddle head” or “cross head”; (3) large fontanelle closure can be delayed until 2-3 years of age; (4) late teething can be delayed until 1 year of age or 3 years of age to come into alignment Severe cases of teeth misalignment enamel dysplasia. (2) Chest: (1) Ribs with beads; (2) Thoracic deformity: chicken chest, funnel chest. (3) Extremities and spine: (1) wrist and ankle enlargement to form rickets “bracelet” and “foot bracelet”; (2) lower limb deformity “O” shaped leg (knee inversion) or “(3) spinal curvature: there can be scoliosis or retroflexion deformity serious pelvic deformity (hip ectropion) female children with serious pelvic deformity can cause obstructed labor in adulthood; Third, other manifestations: head lifting, sitting, standing and walking are late joint relaxation and hyperextension phenomenon abnormal cerebral cortex function conditioned reflex formation Slow language development and anemia. Funnel chest can be divided into congenital and acquired. Acquired is mostly due to one of the manifestations of the systemic symptoms of rickets, while congenital funnel chest is mostly a thoracic disease caused by congenital abnormalities in the development of the sternal ribs. Rickets-induced funnel chest can be cured by reasonable calcium supplementation, while congenital funnel chest can only be treated by surgery. As for whether your child has congenital funnel chest, it is difficult to make a judgment because the information you provided is not very detailed. However, in general, congenital funnel chest rarely affects growth and development until the age of three, so we recommend that even if the child is congenitally born with funnel chest, he or she can wait until he or she reaches the age of three before visiting the hospital to decide whether surgery is needed.
