Here you need to know if its a normal fracture with just a cut in bone it takes 1 month to heal, if there is cut with segmental fracture where the fracture piece is not in touch with bone above and bone below then it takes 2-3 months time to heal. But if there is segmental fracture along with crushed bone pieces then it takes 4-6 month time to heal. Now here you need to see which kind of fracture you are having along with this age as well your diet and calcium with vitamin D tablets also matter a lot for healing. Here you have inform some of the doctors have suggested for bone grafting and some of the doctors have suggested to wait. I suggest if your fracture is healing and is better then what it was before after few months on x ray then Dont worry it will be all right. It may take some time. You need to have good enough of calcium with vitamin D in diet as well as suppliment. But if there is no healing sign even after 3-4 month and it is still as it is means you can try with calcium and vitamin D suppliment for 2 month and see later on x ray. Or else you can go ahead for surgery that is bone grafting. If its paining too much then make sure there is no infection as well no displacement of implant. And you can keep using hot and cold pack for some more relief. I have give you here general guideline but I am sure this will be useful for you. Take care.
