[The ESKA femoral neck prosthesis--an alternative to standard endoprosthesis of the hip joint for patients of younger age groups].

The ESKA femoral neck prosthesis introduces a new metaphyseal anchorage principle for total hip replacements. Primary stability of the conical-oval shaped implant is achieved through the use of a lateral traction screw, and permanent stability through bony growth into the macroporous TRIPO metal structure. The system is used in combination with the standard ESKA acetabulum, and metal-polyethylene, ceramic-polyethylene, ceramic-ceramic and metal-metal articulations are all possible.
