About osseointegration

Osseointegration is a natural phenomenon that has revolutionized the implant industry since the discovery mady by Dr. Per-Ingvar Brånemark in the early 1950's.

A strong connection between implant and bone

Osseointegration is a method for anchoring the prosthesis directly to the bone. In the early 1950s, Swedish Professor Per-Ingvar Brånemark discovered that titanium is not rejected by the body but instead integrates with the surrounding bone tissue. Professor Brånemark named his discovery from the Latin word os – which means bone, and integrate – which means make whole, which can also be expressed as interactive coexistence.

The discovery was initially used for the prosthetic replacement of teeth, but it has since been further developed and is nowadays also used for e.g. facial prosthetics and anchorage of hearing aids. In 1990, Dr. Per-Ingvar Brånemark and Dr Björn Rydevik performed the world’s first surgery in which a patient was implanted with a transfemoral osseointegrated prosthesis in Gothenburg, Sweden. This represented a major milestone in the osseointegrated implant industry and a new opportunity for amputees around the world to improve their quality of life.

Utilizing osseointegration for bone anchored prostheses provides significant benefits compared to conventional socket prostheses

  • Improved moving ability

    With a bone-anchored attachment, you can move more freely but also on a more regular basis, as you will not need to worry about chafing or discomfort.

  • Stable

    A bone-anchored prosthesis is attached without using a socket, which ensures stability, as well as the rapid attachment of the prosthesis without any need for additional tools.

  • Enhanced

    The absence of the prosthetic socket enhances comfort and enables above-knee amputees to e.g. sit more comfortably and also giving patients the ability to cross their legs.

  • Reduced pressure, sores and pain

    Heat, sweating and chafing are all common problems among users of socket prostheses. With the OPRA Implant System, you do not need to think about these problems.

“The other prosthesis ruled my life, it was my master in a way, it’s inevitable…it affected my mood and my interest in doing things that I knew would demand an extra effort. You had to weigh the pros and cons and that’s all gone now. Now it’s actually me…I am in command and not the left leg (socket prosthesis) and that’s a big difference.”
