<s>[INST] Hi, i had bilateral femur fractures. One side I have nearly no pain but the other side is complete opposite. I cannot weight bear on it and also the titanium rod has moved down and snapped the bottom nail. I ve been told that this is good but I cannot do any rehab to get stronger. What do I do? Its been 9 months since the injury. [/INST] Hi, 9 months post injury and fixation, and still tender and painful means some problem with union of fracture, I would suggest you to get fresh X-Rays of your both limbs and send to me so that I can see the level of union that has been attained yet. Also, sometimes subtle infection can be the culprit, which will need blood investigations, CBC, ESR,CRP and sometimes IL6. If you can furnish details we can proceed further on advise on what could be the right course of treatment now. Thanks </s>
