<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a nonunion fibul a fracture. I have had a bone graft and intrnal plate but after 3 months there is still no sign of the bone growing together. I Have no pain snd can walk normally Cani just leave it alone snd use my leg normally or do i have to be very creful until such time as union occurs?  <response>: Hello welcome to ChatDoctorFibula fracture is of concern if its involving lower third of fibula. Only point I want to know is which part of fibula was fractured?and whether there was associated fracture of tibia or not?fibula is involved only with 15 weight transfer, so you are not experiencing any issues with weight-bearing.X-ray are advised to see union nonunion and its causes therefore your X-ray of involved leg along with ankle and knee is desired before we can discuss treatment protocol as all depends upon type of non-union. Please follow up with X-ray so that I can better understand your condition and provide you feasible treatment option. Thanks for visiting ChatDoctorWARM REGARDS Chat Doctor.
