US 2005/0038445 A1 · Instrumentation for repositioning and extracting an artificial intervertebral disc from an intervertebral space

Abstract

Instrumentation for implanting an artificial intervertebral disc includes repositioners/extractors for repositioning and extracting the static trials or the artificial intervertebral discs, each of the repositioners/extractors including a shaft and at least two pins coupled to the shaft distal end and extending in a same direction and perpendicular to a plane passing through the shaft longitudinal axis, each pin being parallel to all others of the pins, wherein the disc includes at least two holes, at least two of the pins being sized, directed, and spaced for simultaneous engagement with at least two of the holes, and wherein such simultaneous engagement enables repositioning of the implant via application of pressure to the shaft.
