Rickets, also known as vitamin D deficiency rickets, is a chronic nutritional disease characterized by skeletal lesions, caused by insufficient vitamin D in children, leading to disturbances in calcium and phosphorus metabolism. The typical manifestation of rickets is incomplete mineralization of the growing long bone epiphyses and bone tissue, presenting as bone softening or deformity. Once rickets is diagnosed, it must be treated aggressively. First, children are given high doses of vitamin D, either orally or through intramuscular injection, with a common practice of administering a single dose of 300,000 units of vitamin D intramuscularly. A month later, a blood sample is taken to measure the vitamin D content; if it is below normal, treatment must continue; if it is within the normal range, it is only necessary to supplement the daily physiological requirement of vitamin D for the child. (Specific medication should be administered under the guidance of a physician.)

Is a square skull definitely rickets?

Square skull is not necessarily rickets; square skull can be seen in rickets and congenital syphilis, especially common in rickets. It is often seen in children with rickets older than 8-9 months, due to a lack of calcium in the bones which leads to inadequate bone deposition and calcification. Under the periosteum of the child's frontal bone, parietal bone, and occipital bone, a large amount of osteoid deposition forms the square skull. Therefore, while square skull is not necessarily indicative of rickets, it is a common manifestation in rickets.

Rickets is a disease characterized by the softening and weakening of bones in children, typically due to inadequate vitamin D.

Rickets is a disease, and its full name is Nutritional Vitamin D Deficiency Rickets. It is caused by a lack of vitamin D in children, leading to a disorder in calcium and phosphorus metabolism in the body. It is a chronic nutritional disease characterized by bone lesions. Its typical manifestation is incomplete mineralization of the growing long bone ends and bone tissue. The symptoms include abnormal development of the bones. Generally, without timely and effective intervention, it may lead to conditions such as pigeon chest, or S-shaped or O-shaped legs, which can seriously affect the child's life later on.

How to treat rickets X-type legs?

If rickets presents with an X-shaped deformity, it generally indicates either an active phase of the disease or the residual phase. During this time, it is advisable to minimize the child's standing and walking at home. For lower limb deformities, muscle massages can be performed. For X-shaped legs, massage the inner muscle groups, followed by internal rotation exercises after massaging the double sliding joints. Typically, early treatment involves corrective rehabilitation techniques, and it is possible to visit a pediatric rehabilitation department for relevant manual treatments. If there is a significant skeletal deformity, surgical intervention may be necessary for correction.

How is rickets diagnosed?

Rickets is a chronic nutritional disease caused by a deficiency in vitamin D, which leads to a disruption in calcium and phosphorus metabolism, resulting in abnormal bone development. Typically, the initial symptoms of rickets are most commonly seen 2-3 months after birth. At this stage, affected children often show neurological symptoms such as excessive sweating unrelated to the season, irritability, particularly in infants under three months old who can become easily agitated, and exhibit straining as if constipated, but these are not specific symptoms of rickets. Early diagnosis generally requires specific tests such as blood biochemistry to check the levels of 125 dihydroxy vitamin D3, as well as calcium and phosphorus levels in the blood, and to see if there is any change in serum alkaline phosphatase. The active phase is mainly characterized by skeletal changes, such as early signs of enlarged fontanelles or delayed closure, late teething, and sometimes a softening of the skull resembling a ping-pong ball, gradually leading to a square skull. Subsequently, changes like pigeon chest or noticeable deformities in the lower limbs such as X-shaped legs, O-shaped legs, or K-shaped legs may appear. Sometimes, there may also be curvature of the spine, with occasional scoliosis. These obvious skeletal changes make the condition more recognizable, though the initial presentations are not very typical, necessitating related biochemical blood tests.

Can rickets be treated with vitamin D3?

Rickets can be treated with Vitamin D3; first, we need to understand the pathology of the disease. It is a metabolic, obstructive disease caused by a deficiency of Vitamin D. Often, this deficiency leads to impaired calcium absorption in the body, causing osteoporosis and bone deformity. Infants typically exhibit symptoms like square skulls, pigeon chests, outward flaring ribs, bow legs, and knock knees. Additionally, it affects the baby's sleep quality. The lack of Vitamin D can increase the baby's neural excitability, leading to poor sleep and easy waking. Moreover, severe cases can affect growth and development. Presence of these symptoms should be confirmed by laboratory testing of 25-hydroxy Vitamin D3 to determine specific levels and choose the appropriate dose of Vitamin D3 supplementation. It is also encouraged to promote children's physical activity and exposure to sunlight to enhance the body's synthesis of Vitamin D, which is beneficial for bone development. (Medication should be administered under the guidance of a professional doctor.)
