Abstract
An instrument system, associated milling or drilling guide and method include use of a trial implant of a size corresponding to an actual implant for the intervertebral space, with a milling guide mounted on the trial implant. The milling guide includes a longitudinal guide chamber which is tapered from a forward end to a rearward end. The system also includes a cutting tool which is received in the guide chamber in order to form a cutout in an adjacent vertebra. This cutting tool includes a bearing member which pivotally engages the rearward end to form a pivot axis for the cutting tool in the tapered guide chamber. Either the milling guide can be inverted to form the cutout in the other vertebra; or the milling guide can be provided with two guide chambers, to be used with one cutting tool moved between them or two respective cutting tools.
