Replantation
1. Literally, the act of planting again. 2. In surgery, the restoration of any part of the body to its original site. Also known as reimplantation.
The Chinese surgeon Zhong Wei Chen (1929-2004) was the “father of replantation.” Dr. Chen was the first to reattach a severed hand with success which he did in 1963. Dr. Chen also developed many microsurgical procedures including techniques for preserving severed extremities, reattaching amputated fingers and thumbs, reconstructing muscles and repairing nerves and blood vessels.
