Rickets has a tremendous impact on both the growth of children and external aesthetics. Patients mainly show irritability, occipital baldness, inversion of the knee, ectropion of the knee, and forward protrusion of the sternum. Early manifestations: Patients with rickets in the early stage usually occur in children within half a year of age, and these babies mostly show sweating, occipital baldness, irritability, irritability and crying, etc. When the patient’s condition is further aggravated, the child will have cranial changes, and the cranium will not only become soft, but also have a ping-pong-like sensation if pressed gently. When the child grows to 7 or 8 months old, the head shape will become square and the head circumference will gradually increase; when the child grows to about 1 year old, he/she may develop a chicken chest, which seriously affects the external appearance of the child. When the baby can sit and stand, it is very easy to lead to spinal deformity, and when the child learns to walk, both lower limbs will bear more gravity, which will lead to serious O-leg or X-leg. The symptoms of rickets are quite diverse and vary from period to period, so we need to learn more about this in order to achieve early detection and treatment.
