It is so confusing. I have exposed bone and a PET scan last week has shown 2 areas of necrotic bone. For the last 6 weeks I had been feeling better and off antibiotics so i was shocked to see it had got worse,before it was only a marginal area of necrotic bone - the bit exposed. my surgeon still recommends taking away the dead bone and sealing it up but I am worried it will cause more trauma to the bone and the ORN will get worse. On the other hand I am afraid to leave it in case it gets worse. Any experience of this position?
