Hand transplantation
Hand Transplantation
Hand transplantation is a surgical procedure to replace a damaged or missing hand or arm with a healthy one from a donor. The procedure is also known as Composite Tissue Allotransplantation (CTA).
Pronunciation
Hand Transplantation: /hænd/ /trænsplɑːnˈteɪʃən/
Etymology
The term "hand transplantation" is derived from the English words "hand", referring to the part of the human body at the end of the arm, and "transplantation", which comes from the Latin word "transplantare" meaning to move from one place to another.
Procedure
Hand transplantation is a complex procedure that involves the connection of bones, arteries, veins, nerves, tendons, and skin of the donor hand to the recipient. The procedure is performed under general anesthesia and can take up to 12 hours to complete.
Risks and Complications
Like all surgical procedures, hand transplantation carries risks including infection, bleeding, and complications from anesthesia. The recipient's body may also reject the new hand, a condition known as graft rejection. To prevent this, patients must take immunosuppressive drugs for the rest of their lives.
