I broke both bones in my left leg, below the knee , on Oct.8, 2012. Today, Jan. 31, 2013, the x-rays show that the bones have not consolidated. There is a plate and 8 screws on the larger bone but nothing was done on the other bone. I have been asked to start physiotherapy putting 25 -50% of my weight (240 lbs) while wearing crutches. Is this OK?
