Human head transplant possible in two years?

The idea is that a head transplant could theoretically extend the life of a person whose body is gravely damaged

Sergio Canavero, an Italian neurosurgeon at the Turin Advanced Neuromodulation Group, has claimed that by 2017 it will be possible to transplant a human head onto another body. The idea is that such operation could theoretically extend the life of a person whose body is gravely damaged, by transplanting his or her head onto another body. This would allow patients to survive and function normally. Sergio Canavero actually envisions performing a transplant on a human - given sufficient financial and legal support - even if other experts say that this proposal is totally absurd, both from a scientific and from an ethical point of view. Canavero said: "I think we are now at a point when the technical aspects are all feasible."

James Harrop, director of Adult Reconstructive Spine at Thomas Jefferson University in Philadelphia and co-editor of Congress of Neurological Surgeons, says that chances of simply surviving a head transplant are roughly 50 percent, while chances to also walk again are zero. "There's 1,000 things that can go wrong when you're getting your head put onto someone else's body," he commented.
