Product Information
Bone sparing
The PROMISE S stem is characterized by an anatomical shape and reduced dimensions thus allowing a minimally invasive approach, preservation of the femoral neck and minimal bone sacrifice in the metaphyseal region.
Physiological load bearing support
The anatomy of the femoral neck and the aspect of the force lines in the calcar region demonstrate an extremely resistant structure with an elevated load bearing capacity. And due to the angled position of the femoral neck, its preservation stabilizes the stem thus avoiding torsion movements.
