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.
