After an accident, Tonney Forsberg had to have his left forearm amputated. This does not prevent the Swede from renovating his house, repairing cars and building all kinds of things. His osseointegrated prosthesis makes this possible. "The change was immense. To experience what I can do with this prosthesis was a big step for me. It’s really good, but I would like to see more reliability in hardware design," Tonney says. After competing in the CYBATHLON 2020 Global Edition, Tonney is eager to compete again.

Osseointegration as a medical technique has been developed in the 1960ies and initially made a name for itself with dental implants. Later, the research shifted towards prostheses and their attachment to the bone. Today, the OPRA team relies on their intelligent technology, which makes sensory feedback possible in everyday life thanks to implanted eletrodes. "Prostheses often have difficulties in their implementation in clinical use, mostly due to reliability problems. Osseointegration solves this problem and enables us to use implantable neuromuscular interfaces in everyday life. We want to help patients regain the functionality lost through amputation and thus improve their quality of life," says team manager Max Ortiz Catalan.
