Osseointegration is derived from the Greek ‘osteon’ meaning bone, and the Latin ‘integrare’, which means to make whole. It is defined as the direct contact between living bone and the surface of synthetic (often titanium based) implant.

Osseointegration’s original application was in bone and joint replacement surgeries and not only has it dramatically enhanced these surgeries and their outcomes but now it is also used to vastly improve the quality of life for amputees.

Clinically it has been used since 1995, utilising a skeletally integrated titanium implant, which is connected through an opening in the stump (stoma) to an external prosthetic limb.  The suction prosthesis is not required and perfect fit is achieved via a torque controlled knee connector.

This allows for direct contact to the ground, which provides greater stability, more control and minimises energy exerted.

The Osseointegration Group of Australia Osseointegration Prosthetic Limb (OGAP-OPL) implant is modeled on the anatomy of the human body and takes the load back to the femur and hip joint when walking. In a traditional socket prosthesis both the femur and hip joint are not loaded naturally which results in degeneration and atrophy of the bone and can lead to osteoporosis.

The OGAP-OPL is suitable for both above and below knee amputees and is implanted directly into the tibia or femur accordingly.
