A method and apparatus for minimally invasive total joint replacement is disclosed. The method involves sculpting the articular surface of a second bone that normally articulates with a first bone by attaching or supporting a bone sculpting tool directly or indirectly to the first bone with the tool in sculpting engagement with the articular surface of the second bone, and then sculpting the articular surface of the second bone with the joint reduced. The reamer system includes a reamer drive, a grater, a handle and a femoral broach.
La présente invention concerne une méthode et un appareil destinés à remplacer totalement une articulation de la manière la moins invasive possible. Cette méthode consiste à sculpter la surface d'articulation d'un second os, qui s'articule normalement avec un premier os, en fixant ou en appuyant un outil de sculpture d'os directement ou indirectement sur le premier os en mettant l'outil en position de sculpter la surface d'articulation du second os, puis à sculpter la surface d'articulation du second os lorsque l'articulation est réduite. Le système alésoir comprend une commande d'alésoir, une râpe, un manche et broche fémorale.
