Organized sports can be very competitive, even for young children. Little League players are often pushed to develop such skills as perfecting a curve ball. However, repeatedly trying to throw a curve ball can cause injury in growing bone
What part of the bone is most likely affected?
Certain repetitive motions place an undue amount of strain on joints. Since the epiphyseal plate in children has not formed solid bone, it also is subject to stress. The process of throwing a curve ball involves a wrist-flicking motion that can compress the growth plates in the bones of the arm and wrist, causing damage to them.
