What is Osseointegration?

Osseointegration offers a surgical method to directly attach the prosthesis to the bone via an implant, thus eliminating the need for a prosthetic socket. Pioneered by Dr Per-Ingvar Branemark in Sweden in the 1960s, the World’s first transfemoral osseointegration surgery was performed in 1990. Since then, Integrum has developed the OPRA™ (Osseointegrated Prostheses for the Rehabilitation of Amputees) Implant System which has been used by hundreds of amputees helping to improve their quality of life.

The OPRA™ Implant System for bone anchored prostheses serves as a stable, direct connection to the prosthetic limb. It is developed for both upper and lower limbs, and is the only system approved by the FDA in the USA. The system utilises a modular design consisting of three main parts that have been developed and refined based on many years of development and clinical research. The unique design ensures protection of the patient by avoiding bone fractures from accidental loads.


Fixture: Anchoring element inserted into the patient’s bone

Abutment: Skin penetrating connection attached to the fixture

Abutment Screw: A screw made of titanium alloy that locks the Abutment to the Fixture
