Self-Centric - Dynamic biarticular head with safety clip
The Self-Centric® biarticular head aligns traction and pressure in one axis and with the positive eccentricity of 2mm leads to a dynamic head adjustment and "stands up" effect. This avoids varus tilting and gives the permanent maximum bone contact during an extensive amplitude of motion. There is little reaction of the acetabulum to the implant because the main articulation takes place between the head and polyethylene inlay. The polyethylene is firmly embodied in the metal shell, preventing micro movements and abrasion.
Handling and assembly is simple and the conversion to a total prosthesis without replacing the femoral stem is easily possible.
