Body Mass Index (BMI). Body Mass Index (BMI) is measure of body fat based on height and weight that applies to both adult men and women. BMI does not differentiate between body fat and muscle mass. Therefore, body builders and people who have a lot of muscle bulk will have a high BMI but are not overweight or obese.
The bump: or hematoma as we call it, can last for 1-2 weeks. Sometimes it gets slightly worse before it gets better. If the child is acting normally, and not vomiting uncontrollably, she should be fine. If she starts doing those things, call your pediatrician.
For the bone to heal, your child will need to wear a sling. The sling helps to keep your child's arm and collarbone still so the bone can heal. Your child may need to wear the sling for about 2 to 3 weeks.fter 10 to 14 days of wearing the sling, the fracture will stabilize and have new bone growth at the injury site. Your child may feel a bump on the collarbone. This is normal; it means that the fracture has healed. The bump will get smaller over the next year, but it may not disappear completely.
