First of all you must decide that physiotherapy is helping you. Your mind is your medicine. In physical therapy are usually strengthening ligaments and muscles so that the bone gets stronger foothold. It is best if you are doing exercises for strengthen at home too, so that the results come sooner (don't overdo it). Second, operation might not also be the worst option because these fracture-if they are incorrect overgrown, will only be once more broken, that they will overgrow correct.. I have problems with ankles since I fell down the stairs when I was 6 years old and I twisted both of them. My ligaments are weak even if I am training, I don't pay attention to the exercises the doctor gave me. Last year I stepped a little wrong during the training and the bone in ankle cracked. I was resting for 2 weeks and then I started with exercises. It relly helped much. Hope you will be ok and don't worry too much, take care.
