You don't necessaily need to connect all the nerves. Some prosthetic arms today instead detected the magnetic fields caused by the nerves, rather than attaching them to the nerves (though some surgery is needed to realign the nerves). However I gather it takes a lot of time to learn how to use it, so I doubt you would really see the "plug n' play" stuff that Yang underwent. She'd require therapy and stuff to help.
