Abstract
A wedge plate inserter/impactor instrument is provided primarily for holding, inserting, repositioning, removing, impacting, extracting, and otherwise manipulating an artificial intervertebral disc having features suitable for being manipulated thereby. A spring-loaded holding pin of the instrument can be used to engage a corresponding hole on the disc and confront the angled surfaces of the disc to enable the holding and manipulation of the disc. A forward wedge extension of the inserter/impactor has upper and lower surfaces that engage inwardly facing surfaces of the disc to hold the baseplates of the disc at a preferred lordosis angle with respect to one another. The instrument can engage the disc from a variety of surgical approach angles.
