I am suffering from right femur mid shaft fracture. I have underwent an operation with traditional nailing. my fracture isn't healing. I am suffering from delayed union. my surgery has been done 6 months ago yet there is very poor calcification seen in x-ray as well as CT scan. I have swelling on my knee and the pain rediates to ankle. i am 18 years old with obesity problem. kindly suggest any option to reduce the pain.
