Claims1
A spinal implant comprising:
- a first member and a second member each comprising a distal end, the distal end of the first member coupled to the distal end of the second member via an interlocking scissor feature positioned near the distal end of each member, the first member further comprising an inner surface, an outer surface and a threaded slot passing through the first member from the inner surface to the outer surface;
- and
- an implant distractor comprising a thread feature, the implant distractor adapted to be advanced between the first and second members and separate the first and second members such that the upper and lower members hinge relative to one another about the interlocking scissor feature,
- wherein the threaded slot is adapted to receive the thread feature, the threaded slot comprises a truncated threaded slot and the implant distractor comprises a cross-cut thread, and the cross-cut thread being engaged with the truncated threaded slot helps to resist the implant distractor from backing out from between the first and second members.
