In 2016, Shreya Sidnagouder, then 18, was seriously injured in a bus accident cutting both hands. Mr. Sidnagouda who lost both hands, but in 2017 performed 20 hours of surgery by 20 surgeons and 16 anesthesiologists and succeeded in transplanting both hands of a man who died at the age of 21 years. did.

After the operation, Sidnagouda continued rehabilitation under a physiotherapist. As a result, Mr. Sidnagouda gradually recovered his athletic ability with his arms and hands, but at the same time, unexpected changes occurred.
This change means that the skin color becomes lighter. The donor's skin was dark brown, but over time the skin color became lighter and closer to Sidnagouda's skin color.
Also, it seems that the transplanted arms have become thinner than at the time of transplantation, but physiotherapist Keaki Dawk thinks that this is because the transplanted arm muscles have accepted the `` host '' I am. 'When 'reinnervation' occurs when the nerves start sending signals, the muscles function according to the body's demands. The arm muscles have begun to accept the female body,' said Dalk.
In addition, Sidnagoudder's mother states that her fingers are getting thinner and longer. The first attempt at transplanting an arm from a man to a woman is unknown, and the exact cause is unknown, but it is believed that female hormones may have changed.

To date, fewer than 200 arm transplants have been performed worldwide, but none of the cases have changed skin color. On the other hand, the number of transplant operations for donors and recipients of different genders is limited, and there is also a problem that research and investigations themselves are limited. The color of the light and shade of human skin is melanin for depends on the amount of, the color of arms that have been ported has become bright, thinking doctors and because Shidonagouda's body does not produce melanin than donor I am. However, further research is needed to give a clear answer.
The transplant recipient was a student from Sachin, a city in Kochi, South India, who was involved in a bicycle accident and was sentenced to brain death, agreeing to his family donating their arms and other organs. Donors who donate their arms will have prosthetic arms, but many families don't like being hurt, so donating arms is very rare.
Some of Sydnagouda's nerves and finger muscles are not yet fully functional, but are expected to improve over time.
