Prosthetic device connects bone, nerves and muscles

Dr Max Ortiz Catalan claims that the device is the first of its kind. One section combines a titanium implant surgically placed into the humerus, along with a control system that connects electrodes to the muscles and nerves in the arm. These internal components are linked to removable prosthesis, maintaining a mechanical connection with the bone and an electrical connection with the implanted electrodes.

According to Dr Ortiz Catalan, the electrodes give the user precise control, as well as providing tactile feedback to the nervous system from the prosthetic. This gives an enhanced level of interaction with the environment and allows handling of delicate objects such as eggs. As the only contact between prosthetic and arm is via the titanium implant, the chafing and inflammation problems associated with traditional prosthetics are avoided.

“By having a direct connection to the bone and not having any components that disturb the skin, the use increases considerably, as well as the quality of life,” said Ortiz Catalan.
