World’s first muscle and nerve controlled arm prosthesis

For the first time a surgical team at Sahlgrenska University Hospital, led by Dr Rickard Brånemark, conducted an operation where electrodes have been permanently implanted in nerves and muscles of an amputee to directly control an arm prosthesis. The result allows natural control of an advanced robotic prosthesis, similarly to the motions of a natural limb.

The operation was possible thanks to new advanced technology developed by Max Ortiz Catalan, supervised by Rickard Brånemark at Sahlgrenska University Hospital and Bo Håkansson at Chalmers University of Technology. “We believe that implanted electrodes, together with a long-term stable human-machine interface provided by the osseointegrated implant, is a breakthrough that will pave the way for a new era in limb replacement,” says Rickard Brånemark.

For more information about the procedure and to see an animation of the advanced technique, please visit Chalmers University of Technology. Dr Rickard Brånemark, along with his team, developed the pioneering implant system OPRA. This means that a titanium screw, so-called osseointegrated implant, is used to anchor the prosthesis directly to the stump, which provides many advantages over a traditionally used socket prosthesis. Overall, it contributes to a better quality of life for people who are amputees.

Osseointegrated prostheses is one of three Centers of Excellence that Sahlgrenska I.C. and Sahlgrenska University Hospital has decided to highlight on an international market. Visit Our Cooperations for more information.
