Mittelfristige Ergebnisse mit dem zementfreien individuellen Femurersatz

: Between april 1985 and march 1989 183 individual hip prosthesis of the Aldinger type have been implanted at the university hospital of Tubingen. The time of follow up was 37.3 months. In the average the patients were 55.0 years old. In 39 patients one or several operations had be done at the same hip joint before the implantation of the individual hip. 7 hip prosthesis had to be removed. In two cases 1 respectively 1 1/2 years after the primary operation an infection of the prosthesis mad a replacement necessary. In five cases a aseptic loosening of the prosthesis occurred. 139 patients were painfree. In 13 patients there was an intensive femoral pain; 4 of these patients showed radiological signs of loosening. 159 Patients were satisfied with the result of the operation. In one case a fissure of the femoral shaft occurred; a fracture of the femoral shaft was not found. Our early results with an individual hip prosthesis are promising, but we have to wait for the long-term-results.
