Dualis

Double Mobility Cups

The concept of DUAL MOBILITY (head-insert and insert-cup) is a tried and tested means of reducing the risk of dislocation and consequent treatment.
The principle is that of combining high articulation stability by means of a large-diameter polyethylene insert and reducing shear forces thanks to the “low-friction” of the head-insert coupling

UNCEMENTED DUALIS

Available in 16 sizes: 42÷72
Three grooves around the circumference for a improved primary press-fit
Spherical shape extended in a cranial direction and protruded edge (+ 3mm) to prevent dislocation
Caudal unloading: prevents conflict with the femoral neck
Mirror finishing on the inside to avoid wear of the polyethylene

CEMENTED DUALIS

Available in 16 sizes: 42÷72
Longitudinal grooves that facilitate proper distribution of cement for an optimum anchoring
Mirror finishing on the inside to avoid wear of the polyethylene

Materials Uncemented Dualis: high nitrogen steel. Double plasma sprayed Ti SPS + HA OSPROVIT coating for greater secondary stability.

Materials Cemented Dualis: high nitrogen steel

DUALIS CEMENTATA E NON CEMENTATA no bordo
