1 COMMERCIAL LEAFLET Inventor of dual mobility Novae range in 1975

2 Novae range Novae concept SUNFIT TH The dual mobility concept was invented in 1975 by Professor Gilles BOUSQUET and the engineer André RAMBERT, the founder of SERF. The main focus of their work was to increase joint stability and reduce surface wear. The system consists of a thin metal back cup into which a mobile polyethylene insert is fitted. This retentive insert, the distinctive geometry of which was patented in 1975, articulates around the prosthetic head. The result is a very stable implant that reproduces the natural anatomy and movement of the joint far more accurately than any other hip replacement system. The dual mobility concept, which was considered ground-breaking at the time, has now been widely adopted.

3 Internal Geometry of the Metal-back shell + 3 mm High quality internal surface geometry and polish. The 3-mm cylindrical extension plays a key role in prosthesis stability, considerably increasing the dislocation distance. External Geometry of the Metal-back shell front The front of the cup features three 120 areas. A ridged pattern is arranged around three slightly higher (by several tenths of a millimetre) points, intented to be positioned opposite to the illium, pubis and ischium. The series of ridges between these three higher points gradually decreases to create a perfect pressfit. The trough of these structures gives the cup s reference diameter. External Geometry of the Metal-back shell from the equator to the pole area + 3mm Volume, the thickness and height of which varies depending on the size of the cup, is added to the equatorial area by numerous ridges (circular spur-shaped grooves broken up by recesses, the base of which gives the cup s reference diameter). The gradual flattening out of the pole around a wide radius (up to 0.5mm) helps to absorb stresses from the base of the cup at the time of final impaction. External Geometry of the Metal-back shell between the equator and the pole area The intermediary area between the pressfit and the pole consists of grooves which contribute to secondary stability once bone in-growth has filled them. The external surface of NOVAE TH cups is coated with both a titanium spray and a layer of hydroxyapatite. This dual coating strengthens its primary fixation stability and increases longevity.
