Instruments and methods for preparing an intervertebral space for receiving an implant. An adjustable trial implant has an adjustable stop mechanism having a stop member connected thereto to vary the distance that a body portion of the trial implant can move into the intervertebral space. Cutting tools for forming cutouts in the adjacent vertebrae use the trial implant and/or a guide to position a cutting tool which may be a burr or a chisel. The chisel cutting tool can be moveable relative to a selected trial implant or the chisel cutting tools can be fixed onto a trial implant shaped body portion.

Instruments and methods for inserting an intervertebral implant. Insertion of the implant is accomplished by grasping the implant between the arms of an insertion instrument having arms which separate from each other and close against each other onto the implant, such that the ends of the arms of the insertion instrument engage recesses of the implant. A spacer may be provided between the arms of the insertion instrument to help position the implant while held by the arms.

摘要:
An instrument and method are disclosed for inserting an artificial intervertebral disc implant having upper and lower parts and a pivot element therebetween into an intervertebral space. The instrument has a mounting structure, and an elongated upper arm and elongated lower arms, the arms being pivotally attached to the mounting structure. A distractor separates the upper and lower arms, and hence the upper and lower parts, when moving along the arms so as to permit insertion of the pivot element. The distractor includes a fork arm that extends beyond a main body thereof to engage and support with heads thereof a facing surface of the upper and/or lower part during and following separation of the parts.
