Aim

The first osseointegrated transfemoral amputation prosthesis operation was performed in Gothenburg in 1990. The aim is improving quality of life for patients who cannot use conventional socket prosthesis. In 1999 the prospective OPRA-study (Osseointegrated Prosthesis for Rehabiliation of Amputees) was initiated with standardized surgery, equipment and rehabilitation program.

Method

The surgery consists of a two-stage procedure. At the primary surgery (S1), a titanium screw (the fixture) is inserted into the remaining diaphyseal bone. The fixture is 80 mm long with a diameter of 16–20 mm (+0.5 mm increments). The patient is hospitalized 5-7 days.

At the secondary surgery (S2), six months later, an abutment is inserted into the fixture. The abutment has a hexagonal press-fitting into the fixture and is secured by an abutment screw. The patient remains hospitalized 10–12 days. Gradual increase of load and activity is initiated over a 6 month period.
