The revolutionary OPRA™ Implant System
The OPRA™ Implant System is the only FDA approved bone-anchored solution for amputees.

What is the OPRA™ Implant System?

Are you still wearing a socket? It’s time to look ahead. The OPRA™ Implant System allows for a direct connection between your prosthetic leg and your bone. Instead of wearing a traditional socket prosthesis, a specialized titanium implant is placed into your femur (thigh bone) to secure the attachment. The Axor™ II is the connection and safety device between the implant and the prosthetic leg. As a result, you’ll be able to experience freedom of movement, improved mobility, and confidence that your leg can be a natural part of you – while leaving behind the daily aches and pains of a socket.

Did you know? The OPRA™ Implant System is the only FDA approved bone-anchored device for amputees.



Traditional sockets can take minutes or even half an hour to properly attach. With the OPRA™ Implant System, you’ll spend less time putting on your leg and more time doing the things you love.


Because the OPRA™ Implant System allows you to attach your prosthetic leg to your bone, you can get a better sensory feedback through your prosthesis and be able to tell the difference between grass, carpet, tile, and more.


Without a traditional socket, you’ll be free from the aches and pains that go along with it. The OPRA™ Implant System enables freedom of movement and allows you to wear your leg all day, every day.
