In-situ-Kopplung eines hohlen Marknagels mit einer gestielten Knieprothese bei periprothetischer Fraktur

Periprosthetic fractures often reveal problems and complications because of poor bone quality. A case report is presented, in which a hollow intramedullary nail was connected, in situ, with the stem of a knee prosthesis (Blauth knee). Two plate osteosyntheses had previously failed. As ultima ratio, a hollow intramedullary nail was placed antegrade on the stem of the knee prosthesis. Afterwards excellent callus formation developed and resulted in consolidation.
