CA 2615721

The present invention provides a method and device for restoring individual patient joint kinematics using minimally invasive surgical procedures. The instrumentation of the invention sculpts the articular surface of a first bone that normally articulates in a predetermined manner with a second bone. The instrumentation includes a bone sculpting tool and a mount for attaching the tool to the second bone. The implant system is comprised of implants that provide intraoperative surgical options for articular constraint and facilitate proper alignment and orientation of the joint to restore kinematics as defined by the individual patient anatomy.

Cette invention concerne un procédé et un dispositif permettant de restaurer la cinématique d'une articulation chez un patient, en utilisant des procédures de chirurgie effractive minimale. A cet effet, le système d'instruments de cette invention sculpte la surface articulaire d'un premier os qui s'articule normalement selon un mode prédéterminé par rapport à un second os. Ce système d'instruments comprend un instrument de sculptage d'os et un support pour fixer cet instrument au second os. Le système d'implants est composé d'implants qui offrent des options chirurgicales intraopératives pour la contrainte articulaire et qui facilitent le bon alignement et la bonne orientation de l'articulation, afin de restaurer la cinématique telle que définie par l'anatomie individuelle du patient.
