A new artificial joint restores important wrist-like movements to forearm amputees. In the new joint, an implant is placed into each of the two bones of the forearm and a wrist-like artificial joint acts as an interface between these two implants and the prosthetic hand. Together, this allows for much more naturalistic movements, with intuitive natural control and sensory feedback.

The device offers a much more natural range of movement, which could dramatically improve the day-to-day lives of many forearm amputees.
