I have a finger deformity and i want to do finger transplant, what are transplantation methods that don't require immune-suppressant drugs?

Your posted question is interesting but likely not one that anyone can answer. I know of no physician in the US that would consider this a worthwhile project & want to be involved. If you want any form of transplant and are not willing to go anti-rejection meds it would never happen. Many finger deformities can be modified by well trained hand surgeons. This would not require those meds.
