Transcripts: The son's bone age X-ray showed that the bone age was only six years old, parathyroid hormone 12.7 (minimum standard 12), serum phosphorus 1.6 (normal maximum standard 1.5), chlorine and sodium were also low. Calcium is normal. Many people say hypoparathyroidism.
Answer: Parathyroid hormone 12.7 (minimum standard 12), normal low, normal. Serum phosphorus 1.6 (normal maximum standard 1.5). High phosphorus is not explained much, and has a lot to do with diet. For example, children who drink milk regularly will have high values. Chlorine is also low and sodium is also low. Calcium is normal,
Q: Currently 136cm tall and 24kg. But this year it is less than 5cm long.
A: The current height is in the 75-90 percentile, which means that for every 100 children of the same age, our child's height occupies 10-25 places, which means that he is taller than an 8-year-old child with a bone age of only 6 years old, indicating that his height growth potential is greater. The weight is in the 25th percentile, that is, for every 100 children of the same age, our child weighs about 75. Children's low weight relative to height is mostly related to poor feeding, such as picky eating and eating too many snacks.
What are the sites of bone age testing?
Bone age is usually measured on the left wrist, but also in the elbow, knee, and feet. The hands and wrists contain a large number of long bones, short bones and round bones, which can represent the growth and development of all bones in the human body to a certain extent. At the same time, the wrist is easy to take pictures, so it is often used for bone age detection.
What are bone age and bone age criteria?
Bone age is the abbreviation of bone age, which is a developmental age that compares the actual degree of development of children's bones with the standard degree of development. Bone age largely represents the true level of development of a child, so it is more accurate to judge a person's maturity by bone age than actual age. Clinically, an individual's bone maturity is compared to a standard map, and when his bone maturity is equivalent to the standard map of a certain age, that age is his bone age, which is an indicator of bone maturity.
Why do doctors often measure the age of children's bones?
The changes in human bone development are basically similar, and the development process of each bone has continuity and stages. Bones at different stages have different morphological characteristics, so bone age assessment can accurately reflect the growth and development level and maturity of individuals. Not only can the biological age of the child be determined, but also the growth potential and sexual maturity trends of the child can be understood as early as possible by bone age: the adult height of the child can be predicted by bone age, and the determination of bone age is also of great help in the diagnosis of some pediatric endocrine diseases. At the same time, it has great guiding significance for the treatment of some short stature patients.
