Why dual mobility? A small head diameter leads to a reduced wear, the principle of «LOW FRICTION». A large head diameter insures maximum stability. The combination of these two concepts enables to reduce wear, while maintaining a good stability thanks to the dual mobility. Longevity and Stability Dual articulation contributes to less wear and more stability: The small articulation, the most solicited one, results in a minimum wear. The large articulation, solicited only during extreme movements, ensures a maximal stability. Around the concept Since the beginning of the 80’s, the dual mobility has proven its clinical efficiency in terms of: - Increased articulation stability - Increased range of movements For primary intention, as well as for acetabular revision and reconstruction, this concept includes a range of homogeneous implants. INTEGRA HAP revision cup Quattro cemented cup / Marc. K acetabular cross Quattro VPS SP HAP cup INTEGRA HAP cup Preventing instability The geometry of the implant, as well as its macrostructure and coating optimize primary stability without screw fixation. 4 tropical spikes preventing tilting Truncated Polar cap avoiding contact with the deep end of the acetabulum and increasing press fit stability Quattro VPS SP HAP cup Size range from 46 to 60* Quattro cemented cup Size range from 44 to 60* Dual mobility liner Size range from 44 to 60, Ø 22,2 and 28 mm* *Please, refer to our complete reference list 7 equatorial fins ensuring rotation stability Cylindrical shape for an increased range of movement VPS dual coating with porous titanium and hydroxyapatite Optimizing reconstruction The Marc. K acetabular cross system acts as a guiding and reinforcement system during the acetabular reconstruction. For this kind of indication, the dual mobility is the best solution for: -limitation of constraints -joint stability Marc. K acetabular cross Size range from 4 to 6, right and left* Quattro cemented cup Size range from 44 to 52* Dual mobility liner Size range from 44 to 52, Ø 22,2 and 28 mm* *Please, refer to our complete reference list Using a strong bone fixation support During the destruction phase of the acetabulum, there is always an area of solid bone remaining (where you can insert a fixation peg in the iliac isthmus). You can use this area (iliac isthmus) to guarantee a good stability for Integra dual mobility cup, avoiding a peripheral legs fixation. In this case, the external legs fixation is no longer required. INTEGRA HAP revision cup Size range from 50 to 62* INTEGRA HAP cup Size range from 50 to 62* INTEGRA insert Size range from 50 to 62* Dual mobility liner Size range from 50 to 62, Ø 22,2 and 28 mm* Cortical screw Length 20 to 60 mm* *Please, refer to our complete reference lis Stability guaranteed without peripheral support Optimizing the dual mobility concept (recognized for over 20 years), groupe lépine stretches out its expertise and skill to offer a range of implants covering all indications. This option ensures combined joint stability and implant longevity.
