DOUBLE MOBILITY PRESS FIT CUP
The Versafitcup Double Mobility is based on the original Dual Mobility design developed by Prof. Bousquet and the Medical School of St. Etienne, France, back in 1976.With more than 30 years of successful clinical history this concept is widely used in Europe and in particular in France, where it represents about 25% of the primary hip cup market. With the introduction of the Highcross Double Mobility liner, the Versafitcup can be considered a valid alternative to hard/hard big head articulation.
DUAL MOBILITY - Articulation Liner/Shell
DUAL MOBILITY - Articulation Head Liner
THIRD ARTICULATION - Articulation Neck/LinerWHY CHOOSE A DOUBLE MOBILITY CUP?Better than standard fixed liner cups:
Low wear rate thanks to the Dual Mobility and Third Articulation.
Low dislocation rate thanks to increased head diameter.
High Range of Motion (ROM) thanks to increased head/neck ratio.In the Versafitcup Double Mobility product range, the minimal diameter of the liner is 38mm for the 46mm cup and increases with 2 mm steps up to 56mm for the 64mm cup. (Liners can be coupled with 28 mm head for acetabular shells from sizes 48 mm to 64 mm; 22 mm head coupling available for shell sizes 46 mm and 48 mm).MATERIAL
Acetabular shell: high nitrogen stainless steel cup, interior mirror finish.Coating: 100 µm plasma-sprayed coating of porous Titanium.90 µm outer coating of HA.Mobile liner: UHMWPE and Highcross poly-ethylene.
The Versafitcup elliptical press-fit cup geometry with equatorial macrostructure and surface effect provides a gradual load transfer avoiding peaks and ensuring excellent primary stability.
