[Allograft transplantation in pelvic instability following prosthesis exchange].
The collective consists of 19 patients with 21 operations after multiple revision operations with complete pelvic instability. The reconstruction was done with tibia (11x) and femur allografts (6x). The bridging was reached by pressfit contact. The junction side was supplemented with autologous bone chips. The allografts were fixed with screws or plates. In all patients a good primary stability was achieved. Partial weight bearing was gained within 10.1 week and full weight bearing in 15.1 weeks. We notice one allograft fracture after 4 months and one infection after 3 months. The reoperation rate was 4. The clinical results are encouraging. No lytic lines were seen between the acetabulum cup implant and the allograft within 20.1 months time.
