Artificial Joint and Bone Implants Restore Wrist Motion in Forearm Amputees

Researchers from the Biomechatronics and Neurorehabilitation Laboratory at Sweden's Chalmers University of Technology demonstrate the restoration of natural wrist movement and rotation in below-elbow amputees. An implant is placed into each of the two bones of the forearm (ulna and radius) and a wrist-like artificial joint acts as an interface between these two bone implants and a prosthetic hand. The researchers' work was published in IEEE Transactions on Neural Systems and Rehabilitation Engineering .
