Reinforcement endoprosthesis

Abstract

The invention relates to a reinforcement endoprosthesis for use in a femoral bone which is resected at an end of a hip joint and at an end of a knee joint. The endoprosthesis includes a stem part of an artificial hip joint and a condyle part of an artificial knee joint. The connecting part between the stem part and the condyle part is configured as a two-piece intramedullary nail which extends inside the femoral bone. One part of the intramedullary nail is a massive intramedullary nail with a connecting portion for a thread and a thread attached thereto and another part of the intramedullary nail is a hollow intramedullary nail with a female thread matching the thread of the first part. The female thread can be screwed with the thread, thereby allowing a length adjustment of the endoprosthesis.
