Junction system for connecting tubular diaphyseal part to metaphyseal part of femoral stem of modular transfemoral prosthesis, has female junction unit with cavity provided with bore at internal wall, where bore is complementary to wedge

摘要

The system has a conical or truncated cone shaped male junction unit (3) with a wedge that is arranged parallel to a longitudinal axis of the male junction unit and protruded beyond a distal end of the male junction unit. A female junction unit (8) includes a conical or truncated cone shaped cavity provided with a bore at an internal wall, where the bore is complementary to the wedge. An independent claim is also included for a modular transfemoral prosthesis comprising a junction system connecting a tubular diaphyseal part to a metaphyseal part of a femoral stem of a modular transfemoral prosthesis.
