Anchor removal instruments and methods for using the instruments are provided. In some embodiments, an intervertebral implant anchor extractor tool comprises a support, a support retainer configured to hold the support fixed with respect to the implant, an extractor having an anchor retainer, and an extractor guide. An embodiment of a method of using this implant anchor extractor tool comprises the steps of obtaining access to an anchor, grasping the anchor, and applying a withdrawal force on the anchor while applying a countervailing force against the implant or a vertebral structure.

Instruments and methods for removing fixation devices from intervertebral implants

Anchoring devices, anchoring systems for intervertebral implants, intervertebral implants, and instruments and methods for implanting implants are disclosed. In preferred configurations, these various objects share the feature of comprising or cooperating with an anchoring device () having a body comprising at least one curved plate () elongated along a longitudinal axis (L), designed to be inserted through a passage () crossing at least a part of implant (), in order to penetrate into at least one vertebral endplate and attach implant () onto this vertebral endplate by means of at least one stop retaining the implant, characterized in that the body comprises at least one longitudinal rib () on at least a part of at least one of its faces, said rib () being designed to cooperate with a groove () made in passage () of implant (). In some preferred configurations, anchoring device () comprises withdrawal stops or latches (), and/or means () for withdrawing the anchor from an inserted position.

The present invention relates to an interspinous implant, intended to be implanted between two adjacent dorsal spines, each including an upper edge, a lower edge and two opposed lateral faces, wherein the implant includes at least one body with dimensions arranged so as to maintain or restore a distance between the adjacent edges of the two spinous processes and including at least two wings extending so that at least a part of each wing lies along at least a part of one lateral face of one of the two spinous processes and, additionally, at least one retainer for the implant, designed to retain the body of the implant between the two spinous processes and to be inserted from the same lateral face as the body.
