Joint fusion surgery is mainly to fix the necrotic phalanx with the adjacent normal bone, so that they can be fused into a bone in the later healing process. This kind of operation can solve the pain problem of your toes now, but because the joints of your toes are fixed, it will have a certain impact on your toe movement function in the future. However, it also depends on the position of the phalanx. If it is not the proximal phalanx, the impact will be relatively small. The biggest point of this kind of operation is that the treatment cost is relatively cheap, and it may be done within 10 thousand yuan. The effect of artificial prosthesis replacement is relatively better, but the operation cost is relatively high, and there may be the possibility of reoperation after 10 years. Therefore, it's up to you to choose which operation method.
It can be said that taking medicine or sticking plaster in some advertisements can't cure osteonecrosis. It's like boiling an egg, and then no matter what medicine you use, it's impossible to turn the boiled egg into a raw egg again. The same is true of many pathological changes in the human body. Once it happens, it is irreversible.
So I suggest you go to a regular hospital for treatment, otherwise spending money will not be good for your illness. If it is joint fusion surgery, any regular hospital above grade 3 will be fine. However, if you want to do artificial toe replacement, I suggest you go to a hospital with a relatively professional ankle surgeon for surgery.
