Abstract

Instrument set for fitting an intervertebral prosthesis, comprising a guide device ( 4 ) for an instrument or a prosthesis part, which guide device ( 4 ) is to be secured on at least one vertebral body ( 2 ). To be able to attach the guide device ( 4 ) precisely on the vertebral bodies despite the difficult operating conditions, an adjustment instrument ( 10 ) is provided which positions the guide device when this is being arranged on the vertebral body ( 2 ). This adjustment instrument ( 10 ) expediently comprises an intervertebral plate ( 11 ) which is fitted into the intervertebral space so as to be positioned exactly in relation to the vertebral bodies.

Claims (10)

1. A method for fitting an intervertebral prosthesis into an intervertebral space between two vertebral bodies, comprising:

removing an intervertebral disk,

positioning and securing an intervertebral plate of an adjustment instrument in the intervertebral space,

sliding a hub of a guide device onto an adjustment rod projecting from the intervertebral plate in such a way that the guide device defines two guide axes made by through holes in a median plane above and below the adjustment rod and parallel thereto,

introducing two pins into the vertebral bodies in the direction of the guide axes,

thereafter, connecting a distraction forceps to the pins so that they are held parallel to one another,

removing the guide device from the adjustment rod,

setting a spacing of the intervertebral bodies,

removing the adjustment rod, and

working the intervertebral space as desired, thereby fitting the intervertebral prosthesis.
