The cemented, collared, tapered stem which is wedge shaped, reduces shear stress while increasing the compress stress and tensile hoop stress. This provides reduction in subsidence and promote rotation stability with excellent self-locking taper.
The connecting taper to ball head has clinically proven 12/14 taper with surface roughness. This enables both metal taper and ceramic head to fit with more stable configuration.
Proximal textured surface increase strength of cement-stem interface.
The cement collared stem is composed of Co-Cr alloy with neck shaft angle formulating 132 degrees. It is also design to have anatomical medial curve within the neck.
Grit blasted satin surface finish on entire stem shaft.
