Abstract

A method and apparatus for minimally invasive total joint replacement. The method involves sculpting the articular surface of a second bone that normally articulates with a first bone by attaching a bone sculpting tool directly or indirectly to the first bone with the tool in bone sculpting engagement with the articular surface of the second bone, and then sculpting the articular surface of the second bone with the joint reduced and moving one bone with respect to the other. An implant is placed to replace the articular surface of the second bone using an impaction device directly or indirectly attached to the first bone.

Claims

1. A system for imparting force between adjacent first and second bones to seat an implant in the second bone, the system comprising:

an implant; and

an impaction device including an attachment portion slidably receivable by a bone mount placed in the first bone, the impaction device including a handle having a curved shaft and first and second ends, said first end including a strike plate threadably received thereon and structured to receive an impaction force, said second end structured to receive said implant, wherein upon application of force to said strike plate the implant is press fit in the second bone, said force reacted by said adjacent first and second bones.
