REVISION OF CEMENTED HIP ARTHROPLASTIES - 101 HIPS FOLLOWED FOR 5 (4-9) YEARS

101 hips were revised with cemented Lubinus prostheses after failed pr imary cemented arthroplasty, and followed for 5 (4-9) years. Radiograp hically, 41 hips (36 femoral stems and 13 acetabular components) had b ecome loose. The use of an intramedullary plug at the revision did not prevent sinking of the prosthesis. No difference was found between co nventional or pressure-injection cementation techniques. In cases wher e the stem was inserted in varus or the acetabular component was in ma lposition there was increased loosening. Patients below 50 years of ag e had oftener more than 5 mm sinking of the stem and more prosthesis l oosenings.
