Revision acetabular prosthesis Novae® Coptos TH

cementless

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. 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 INSTRUMENTS One instrumentation set common for all Novae® acetabular cups. Additional set for pegs and screw preparation for Novae® Evolution TH and Coptos TH. INDICATIONS Acetabular cups combining “Coptos TH” cups and CI E liners are intended for treatment of the following conditions: Patients with a risk of instability (neurological, tumour, revision, dearthrodesis, cognitive issues, etc.) Initial post traumatic surgery Cases that require one or several extra anchors Surgical revision (including chronic dislocation, loosening) if the bone reconstruction allows, Paprosky type IIA, IIB, IIC and IIIA bone defects
