An intervertebral implant inserter, comprising:

Expandable trials

An expandable implant is made via a central strut having a pivotable arm on each end. The implant can be inserted into a disc space either horizontally or vertically with the arms in a closed position and then (if inserted horizontally) optionally rotated up into place. The arms are then pivoted out, thereby increasing the foot print of a horizontally inserted implant. The expanded implant can be locked in place through the use of an additional insert or ratchet that fits between the arms and locks the arms in place.

The present invention provides a system, device, instruments and methods for inserting and/or improving the holding strength and purchase of a bone screw, bone pin, or bone dowel in bone. Embodiments include monolithic allograft tissue forms, multi-piece allograft tissue forms, distally expandable portions, partially and fully demineralized portions, and flexible connecting portions. Advantages of the allograft tissue forms of the present invention include improved pedicle screw blackout strength and improved filling of bone voids. Methods for making and instruments and techniques for inserting the augmentation device, system and screws or pins are also disclosed.
