Cemented or non-cemented acetabular prosthesis Novae®

The Novae® range is based on the Dual Mobility concept invented in 1975 by Professor Gilles BOUSQUET (Saint-Etienne University Hospital) and Mr André RAMBERT, founder of SERF. Dual Mobility is the combination of two principles in orthopaedics: Sir Charnley’s low friction concept: use of thick polyethylene with a small 22.2 mm head to reduce wear. The McKee-Farrar concept: use of a large head to reduce the risk of prosthesis dislocation and instability. The Dual Mobility design is made of two bearing surfaces : Small articulation (or first mobility): articulation of the prosthesis head in the insert. Large articulation (or second mobility): articulation of the insert in the cup. CHARACTERISTICS AND MATERIALS The Novae® cup range includes 5 implants: Novae® SunFit TH is intended for cementless fixation due to its equatorial press-fit and dual coating. Novae® Evolution TH has two pegs secured with fixing screws (one for the Novae® E TH) to complete bone anchoring. Novae® Coptos TH has two pegs secured with fixing screws (4 screws for the Coptos TH) to complete bone anchoring. Novae® Stick must be cemented to the bone and may be combined with the Novae® K E cross plate. Novae® K E cross plate. Novae® implants are made from the materials listed below: Cementless cup: Stainless steel + dual coating made of titanium spray and HA. Cemented cup and fixing screw: Stainless steel. Pins: Alumina-coated stainless steel Novae® K E cross plate: Stainless steel and PMMA CI E liner: UHMWPE
