Hi Sophie411,
Sorry to hear about your diagnosis. I wish I could put a positive spin on it for you...I had surgery in October last year, where I had a mass removed from my leg (they were initially worried about it...but biopsy came back all clear). They believe that this mass may have contributed to the lack of healing. They also stripped the tibia down and completed a tibial release procedure they then cut a wedge out of my tibia to try and stimulate bone growth. The rehab from the surgery has been a long and frustrating one, I was still on crutches until March, then downgraded to a moonboot - which I got off 2 weeks ago. I am now able to walk unaided. We will not know if the surgery has been a success yet - they were trialling this procedure and hoping it would heal so that I could avoid the IM rod. Still same rehab but a little less intrusive. If successful sport is still another 2 yrs off if at all. They did say that it was biomechanics so could come back.
Good luck - hopefully your recovery is a little speedier than mine.
