Delayed Femur Fracture Healing in Children: Understanding the Situation

Question
My 5 year old son suffered a femur fracture (closed) in a bicycle accident 4 weeks ago. He was immediately placed in a spica cast which is supposed to come off in 2 weeks. We were told yesterday that the bone looks only "ok", and that instead of being out of a cast in 2 weeks, he will be moved to a long leg cast for an additional 2 weeks. Our orthopedist set the bone so that it overlaps to account for faster growth, but the x-ray now shows the bone at a serious angle. There are no nails, pins or plates, and we are concerned about his leg not healing properly. Should we seek a second opinion, or should we simply stay on our course of action? Any input you can provide would be appreciated.

Answer
There are certain rules that if the bone is at a certain angle, there is no need to straighten or operate... those angles sometimes are 20-30 degrees.  However, kids heel differently from adults and if it were my child, I would make sure I was seeing a pediatric (child) orthopedist.  He may say the same thing, but they are a little more used to working with kids and bones that have not attained full growth yet.  Hope this helps....
