A system is disclosed for distracting a disc space in a cervical spine at a level adjacent to a previously operated disc space where, in the previous surgery, a cervical plate has been applied to the anterior of the spine to span the previously operated upon disc space and where the cervical plate is attached to the vertebrae bodies on opposite sides of the previously operated upon disc space with the cervical plate covering at least a portion of the vertebrae bodies. A conventional distractor post is screwed into a third vertebrae body, and a second distractor post or member is fixedly and removably secured to the cervical plate. A conventional distractor instrument is applied to the posts of both distractor posts for applying a distraction force to the vertebrae bodies delimiting the disc space to be operated upon. A surgical method of distraction is also disclosed. |
