Title
(EN) ORTHOPAEDIC IMPLANT SYSTEM WITH BONE CONSERVING FEATURES
(FR) SYSTÈME D'IMPLANT ORTHOPÉDIQUE AYANT DES CARACTÉRISTIQUES DE CONSERVATION DE L'OS
Abstract
(EN)
A tibial insert includes an articular surface and a bottom surface opposite the articular surface. The bottom surface includes one or more bone-conserving features. In some embodiments, the bottom surface may be curved to match a curvature of the articular surface such that a thickness of the tibial insert is relatively constant. In other embodiments, the bottom surface may be relatively planar but include a protrusion extending from a planar base surface to maintain a minimum thickness of the tibial insert. The described features may be incorporated in a uni-compartmental tibial prosthesis, a bi-compartmental tibial prosthesis, or a total knee prosthesis.
(FR)
La présente invention concerne un insert tibial qui comprend une surface articulaire et une surface inférieure opposée à la surface articulaire. La surface inférieure comprend une ou plusieurs caractéristiques de conservation de l'os. Dans certains modes de réalisation, la surface inférieure peut être incurvée pour correspondre à une courbure de la surface articulaire de telle sorte qu'une épaisseur de l'insert tibial est relativement constante. Dans d'autres modes de réalisation, la surface inférieure peut être relativement plane mais peut comprendre une saillie s'étendant à partir d'une surface de base plane pour maintenir une épaisseur minimale de l'insert tibial. Les caractéristiques décrites peuvent être incorporées dans une prothèse tibiale à compartiments multiples, une prothèse tibiale à deux compartiments, ou une prothèse totale du genou.
