Bone anchored prostheses are an innovative technology based on osseointegration. It allows the direct connection of an artificial limb (prosthesis) to the patient´s skeleton, thus avoiding the use of a socket. A bone anchored prosthesis will always fit, attach fast and correctly, and since it is not supported over the skin, all issues related to the sockets are eliminated. It allows wearing the prosthetic limb continuously with higher wearing comfort, endurance, and furthermore, only a bone-anchored prosthesis provides the liberating possibilities of free movement and osseoperception.
The OPRA (Osseointegrated Prostheses for the Rehabilitation of Amputees) Implant System is the pioneering treatment for bone anchored prostheses. It is based in decades of extensive research and experience in osseointegration since its discovery in the 1950’s by Prof. PI. Brånemark. Over 200 patients have been treated with the OPRA Implant System up until 2012, and keep reporting functionality for up to 20 years after treatment. The OPRA treatment offers a higher degree of freedom in daily routines and improves quality of life.
The OPRA Implant System consists of an anchoring element (the Fixture) and a skin penetrating connection (the Abutment), which is surgically inserted into the bone of the amputation stump in 2 separate surgical sessions. The patient’s prosthesis is then attached to the outer part of the Abutment through a connection device.
Bone anchoring of amputation prosthesis is a pioneering treatment, built on experienced concepts that improves the quality of life for amputees and their families.
