[|Human|] My son had a bike wreck. He landed on his elbow. He had elbow pain and could not extend his arm fully. Dr. could not see the fracture on X-ray but fat pads were pushed out. Sail sign. He was put in a cast for 5 weeks. It has been off for a week and a half. He still cannot extend his arm much more than he could after the wreck. What do you suggest?
[|AI|]  Hi, thank-you for providing the brief history. As per the history it looks to me that post wreck injury the bodies protective mechanism has started and to safeguard the joint, the muscles have gone into spam and contracture for time being. I will advise you to wait till the cast is removed post which with physical therapy your son will regain the full elbow functionality. This is a common reaction and there is nothing to worry.
