The fastest growing bone in the human body is the tibia, which is the larger of the two bones in the lower leg. It's responsible for bearing the majority of the body's weight.
Antlers are the fastest growing bone tissue in the animal kingdom. They can grow an inch per day and a moose can grow an 80-pound rack in a summer.
The growth plates in bones, which are the areas of cartilage that allow for bone growth, are particularly vulnerable to injury during childhood and adolescence. This is because these plates are still developing and are not as strong as the surrounding bone.
Sever's disease, which affects the growth plate at the end of the heel bone, is a common example of this type of injury.
