Endoprosthesis design is based on the geometry of the femur in regard to the biomechanical properties which will be parametrized through the new endoprosthesis research.

Endoprosthesis length and basis position, manufacturing material and endoprosthesis surface geometry are sellected considering the femur's geometry and type, the hip’s damage degree and the patient’s age. The outcome is the best support for the femur prosthesis, the proper stress for the bone in order to avoid atrophy causing bone-chalasis and the facile insertion of the implant during surgery.
