OPRA™ Implant System

Get your life back with the OPRA™ Implant System


The OPRA™ Implant System is an innovative method allowing the direct connection of an artificial limb to the skeleton. The prosthesis is firmly attached through a quick connection, which lets your prosthesis become a true extension of your body and mind, controlled by you. The system is available for both upper and lower limbs, and has given hundreds of amputees from all over the world the ability to once again enjoy what most people take for granted – ordinary, wonderful, daily stuff like free movement or feeling the ground you are walking on.


What is the OPRA™ Implant System?

The OPRA™ Implant System is a bone-anchored prostheses system based on osseointegration, where the prostheses are directly attached to the bone and therefore avoiding the use of a socket.

  • The system consists of three parts; an anchoring element (the Fixture) and a skin penetrating connection (the Abutment), secured with a screw (the Abutment Screw).
  • The unique design ensures the protection of the patient by avoiding bone fractures from accidental loads.
  • The system has been used by hundreds of amputees since the world’s first surgery in 1990 and has been proven in several clinical studies.

How does it work?

The OPRA™ Fixture is coated with a new surface technology, BioHelix™, that has been developed by Integrum after 15 years of research and clinical testing. The surface will take osseointegration to the next level and promote faster, stronger attachment to the bone, thereby increasing the strength of the bone-to-implant interface. The prosthesis is connected to the OPRA™ Implant System using a connection, load controlling device. Integrum has developed specific components each customized for different indications levels, including both upper and lower limb.

Benefits of the OPRA™ Implant System

  • Elimination of Socket Related Problems (Hagberg et al 2014)
    • Skin irritations, ulcers and perspiration – all eliminated
    • Allows volume fluctuation and weight gain/loss
    • Greater comfort during sitting
  • Enhanced Proprioception & Osseoperception (Häggström et al 2013)
    • Intuitive awareness af limb positioning in space
    • Increased sens of feel through the prosthesis
  • Ease Prosthetic Attachment (Carroll et al 2006)
    • Donning and Doffing in less than 10 seconds
    • Extremely easy and the same way every time
  • Increased Range of Motion and Limb Strength (Hagberg et al 2008)
    • Wear time and daily steps increase
    • Improved force production in residuum

Bone-anchored Prosthetics

The science behind bone-anchored prosthetics is powered by the principles of osseointegration. Osseointegration relates to the ability for certain implant materials to interact with bone in a way which makes the interface between the implant and the patient’s bone produces solid fixation.

The entire field of osseointegration was established by the pioneering work of Prof PI Brånemark, who in 1962 identified complete titanium integration into bone while studying microcirculation in the bone of an animal model. Over the past 50 years, this discovery has lead to new treatments and entirely new fields of medicine. The impact of osseointegration has helped millions of individuals with the technology applied to restoration of teeth by way of the modern dental implant and the bone-anchored hearing aid.

Prof PI Brånemark and Prof B Rydevik performed the first surgery in 1990, rehabilitating a female transfemoral amputee who had been unable to use a traditional socket prosthesis. Dr. Rickard Brånemark, orthopaedic surgeon and Integrum’s Founder, expanded upon his father’s pioneering work and applied the principles of osseointegration to rehabilitation and transfemoral amputees.

“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. ”
