The approved cone design of the 3Con stem is developed for cementless application and follows the pressfit anchorage mechanism.
The design with curved lateral overlap supports the proximal seating and optimizes the anchorage stability of the stem-bone system.
It is characterised by extra-ordinary stability and longevity minimising implant rotation.
It is possible to switch intra-operatively from the cementless 3Con to the cementable CemtA Stem procedure without further additional instruments.

The press fit anchorage procedure of stems requires the accurate filling of the femoral diaphysis. To achieve the needed geometric accordance between the femur and the stem implant,1mm upscaling of the stem from one to the next size can be a too huge step.
The new and additional intermediate sizes reduce the upscaling steps of the stem dimensions from previous 1mm to 0,5mm.
