For patients with a leg amputation who experience problems when wearing a socket prosthesis, there is now a new method for anchoring the prosthesis to the body. The surgeon can insert an orthopedic implant made of titanium through the skin directly into the bone of the stump. The leg prosthesis can be attached to this implant by means of a quick release click system. In The Netherlands this new technique is called a click prosthesis. Doctors use the term osseointegration prosthesis. The skin opening through which the implant protrudes is called a stoma.
What is the principle of osseointegration?
The osseointegration prosthesis comes from dentistry. In the sixties, the Swedish dentist Branemark discovered that bone adheres very well to the surface of a titanium screw. This tight connection of metal with bone is called osseointegration and this principle is now used by orthopedic surgeons to fixate hip and knee prostheses to the bone. Since the 1990's the osseointegration technique has also been developed for people with an amputation. Unlike a hip or knee prosthesis, the implant protrudes through the skin so that an arm or leg prosthesis can be clicked on. Since 2009, the osseointegration (click) prosthesis has also been used in the Netherlands in people with arm or leg amputation.
