ALLOGRAFT TRANSPLANTATION AFTER MULTIPLE REVISION OPERATIONS WITH COMPLETE PELVIC INSTABILITY

The collective consists of 19 patients with 21 operations after multip le revision operations with complete pelvic instability. The reconstru ction was done with tibia (11 x) and femur allografts (6 x). The bridg ing was reached by pressfit contact. The junction side was supplemente d with autologeous bone chips. The allografts were fixed with screws o r plates. In all patients a good primary stability was achieved. Parti al 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 re sults are enchouraging. No lytic lines were seen between the acetabulu m cup implant and the allograft within 20.1 months time.
