In January 2013, Dr. Rickard Brånemark led the world’s first surgery where neuromuscular electrodes were permanently implanted in an amputee, connecting prostheses to the patient’s bone, nerves, and muscles. Today, robotic prostheses controlled via implanted neuromuscular interfaces are about to become a clinical reality thanks to Integrum’s osseointegrated technology. This technology is under development and currently in an ongoing clinical trial, and as soon as it is CE-marked, it will be the natural upgrade for people using the OPRA™ Implant System.
The Next Generation Robotic Arm
Conventional robotic prostheses available today are attached with a socket and controlled via electrodes placed on the skin. Robotic prostheses can be very advanced, but such a control system makes them unreliable and limits their functionality, and patients commonly reject them as a result. By connecting the prosthesis directly to bone, nerves and muscles, the Integrum robotic system can provide a significantly improved user experience.
- Unrestricted range of motion
- Precise and reliable prosthetic control
- Direct and intuitive neural sensory feedback
- Stable mechanical attachment
- Reduced phantom limb pain
Magnus – a Man Who Made History
Magnus, 42 years old from Haparanda in Northern Sweden, was the first person to receive a prosthesis directly connected to bone, nerves, and muscles. Thanks to his new robotic arm, Magnus has been able to cope with all the situations he faces in his physically demanding job driving trailers in between Sweden, Norway, and Finland.

How Does it Work?
The technology is built around the OPRA™ Implant System and has been developed in close collaboration with Chalmers University of Technology and Sahlgrenska University Hospital. The artificial arm is directly attached to the skeleton, thus providing mechanical stability. Then the human’s biological control system, that is nerves and muscles, is also interfaced via neuromuscular electrodes to the prosthesis via Integrum’s advanced control system. This creates an intimate union between the body and the prosthesis; between biology and mechatronics.
The stack connector interfaced with a pin connector extending from the central sealing component, from which leads extended intramedullary and then transcortically to a final connector located in the soft tissue. The leads from the neuromuscular electrodes are mated to connector.
