Hi, my son is 4 years old. He has had joint laxity since he was born. His had congenital left hip dislocation and was operated for that twice. He had a fall just before his second surgery which was done to remove the plate in his leg. The doctor suspected a mild fracture but it was not visible because he was in lot of pain and refused to walk. He placed him in plaster for 6 weeks. After which he started walking slightly. One day he fell again while slowly running and his ankle twisted. He was bed ridden for quite some time beccause he had severe back painl. We got x ray done and the doctor determined that his L4 and L5 were compressed. He recovered aafter weeks of rest. But now a year since then after a minor fall is complaining of slight back pain......
