broken fibia no X Ray ????????

Hi there I had spiral fractured my fibia they said I will need a plate and screws in it because where they jion at the ancle they came apart a month after surgery I went in to get an X-ray and he said just take the cast of and try to walk on it if it hurts take some pressure off. Is this the proper procedure??? I can’t put pressure on my foot because it hurts and that is why he said to work into it?? how does he know if it is healed properly with out an X-ray???
