A little background. My 6 year old son had a spiral fracture of his tibia in july.( the fracture was not near his growth plates) He wore a long leg cast for 5 1/2 weeks and a short cast for 3 1/2 weeks. He was permitted to start walking on it after 4 weeks. After his cast came off they said he would limp and his foot would turn out for a couple of months...They did not want to send him to physical therapy because they said the best therapy would be playing and just being an active 6 year old.. which he is very much.
3 months later, He is in pain around his knee. His foot is still turning out, but his knee is facing forward. If he forces his foot forward then his knee turns toward his other leg. We brought him back to the orthopedic doctor and he decided to send him to physical therapy for only 1 month.. He didn't even get more x-rays or an mri or anything to look at his leg. He diagnosed him with cast disease.. Hence, my question. What is cast disease? I can't find any information on it. I'm really bothered by this because the physical therapist that checked my son out noticed that his leg that was not broken appears to be about an inch shorter then the leg he broke. So she measured his legs from his hip bones and it's not that it's shorter.. it's that his hip bone is higher up and when he bends over he has a hump on his back.. So everything is out of alignment. Any info on this or ideas would be greatly appreciated. His physical therapist and myself are completely baffled by this. Thanks in advance.
