The wrist is continuing to progress. As far as I know it has not become a commercial product yet, but a number of the prosthetic manufacturers are involved in the development. The goal is to design a disconnect that is different than the existing design (originated by Otto Bock) that would allow for a stronger connection. As you know with your hand, it is easy to rotate the hand at the wrist. A powered (or locking) wrist can only be as strong as the force it takes you to spin it.
Liberating Technologies, Motion Control, RIC, and UNB (and I think also Steeper and Touch Bionics) have all been involved as the design progresses. If you are interested in learning more, I would suggest contacting Jon Sensinger who was at RIC and has moved to UNB.
