Question
When do newborns develop hip bones?
Answer
Hip bones in newborns typically begin to develop within a few months after birth, but it may take several years for them to fully mature. The hip bone develops due to the growth and fusion of the epiphysis plate at the top of the femur. The epiphysis plate is a special layer of cartilage responsible for the growth of long bones. During infancy, the epiphysis plate of the hip bone has not yet fully fused, so the hip bone is still developing. Generally, a girl’s hip bone may fuse before puberty, while a boy’s may fuse after puberty. However, the exact timeline varies from person to person and is influenced by many factors, including genetics, nutrition, and overall health status. To ensure normal development in children, it is recommended to monitor their growth and consult a doctor if necessary.
