Hand transplantation

Common card · No. 421085

Hand transplantation, or simply hand transplant, is a surgical procedure to transplant a hand from one human to another. The donor hand, usually from a brain-dead donor, is transplanted to a recipient amputee. Most hand transplants to date have been performed on below-elbow amputees, although above-elbow transplants are gaining popularity. This was the first of a new category of transplants in which multiple organs are transplanted as a single functional unit, now termed "vascularized composite allotransplantation" (VCA). The operation is extensive, and typically lasts from 8 to 12 hours. In comparison, a typical heart transplant operation lasts 6 to 8 hours. Surgeons usually connect the bones first, followed by tendons, arteries, nerves, veins, and skin.
