The Osseointegration Group of Australia Osseointegration Prosthetic Limb (OGAP-OPL) implant is made up of several components. The components can be divided into an inner (endo) module and an external (exo) module.
The endo module, a titanium stem, is directly implanted into the bone.
The implant surface is made of highly porous titanium, which allows initial stability and long term bone integration (ingrowth). This technology has been successful in clinical use world wide for more than 30 years in joint replacement surgery. The biocompatibility of the titanium implant allows the bone to grow inside the surface of the prosthesis, which makes the bone and implant structure one solid unit. This is known as osseointegration.
A dual adaptor connects the internal implant to the external prosthesis. This adaptor has a highly polished smooth surface to minimise soft tissue friction. It is also coated with a titanium niobium, which has antibacterial properties. The dual adaptor passes through a small opening in the skin at the end of the stump known as the stoma. Externally the adaptor is fixed to a torque control safety device which further connects to the prosthetic limb.
Taking on and off the prosthesis is very easy and takes less than ten seconds. Due to the solid fixture to the bone it accurately connects in the exact spot each and every time you attach the prosthesis. This device can be used with all types of prosthetic knee units and lower limb prosthetic componentry.
Gone are the days of fiddling around with time consuming and cumbersome suction, socks and liners.
