Title
(EN) IMPLANT WITH MULTI-DIRECTIONAL PIVOTING
(FR) IMPLANT À PIVOTEMENT MULTIDIRECTIONNEL
Abstract
(EN)
Implant with multi-directional pivoting has a first component including a first articular surface and a fore-to-aft and side-to-side rotation device; and a second component including a second articular surface for mating with the first surface and a rotation device receptacle. The first component can be mated to the second through cooperation of the rotation device and receptacle, and the first component can cooperate with the second in articular surface contact. The joint may be a knee prosthesis comprising first femoral and second tibial components, with the first surface a femoral condylar surface and the second surface a tibial condylar surface. Therein, the fore-to-aft component can be considered flexion, with the side-to-side component considered version. A knee prosthesis can also be provided with a patella support on a smooth counter surface from full extension to flexion well past 100 degrees and/or with a mechanism preventing excessive downward tibial component travel.
(FR)
L'invention concerne un implant à pivotement multidirectionnel, qui comporte un premier composant comprenant une première surface articulaire et un dispositif de rotation avant-arrière et latéral ; et un second composant comprenant une seconde surface articulaire en vue d'un appariement avec la première surface articulaire et un récipient de dispositif de rotation. Le premier composant peut être apparié au second composant grâce à la coopération du dispositif de rotation et du récipient de dispositif de rotation, et le premier composant peut coopérer avec le second composant par mise en contact des première et seconde surfaces articulaires et par articulation de l'articulation lorsque le premier composant est apparié au second composant. L'implant peut être une articulation artificielle qui a généralement une capacité de transfert de charge naturelle. Dans un mode de réalisation particulier, l'articulation est une prothèse de genou ; dans ce cas, les premier et second composants sont des composants fémoral et tibial, la première surface articulaire étant une surface condylienne fémorale et la seconde surface articulaire étant une surface d'appariement condylienne tibiale. Dans un tel genou, le composant avant/arrière peut être considéré comme étant une flexion, le composant côté/côté étant considéré comme une bascule. Ainsi, une prothèse de genou peut être dotée d'un dispositif pour supporter la rotule sur une contre-surface lisse de l'extension totale à la flexion bien au-delà de 100° et/ou par mécanisme pour empêcher un déplacement vers le bas excessif du composant tibial.
