Your child has been placed in a Petrie cast to keep the ball of the femur (the thigh bone) in the hip socket. He / she will adjust to the position shortly, and will be able to resume many normal activities.
Your support in helping your child adjust is very important. If your son or daughter had surgical release of some of the tight structures about the hip, you may see some swelling near his / her groin areas, or private parts, for three to six weeks. If the swelling becomes worse or does not decrease after this time, notify your child's doctor.
