Translational scissor plate fixation system
First Claim
1. A fixation assembly comprising:
- a first fixation device having a first opening configured to receive a first bone fastener, and a second opening configured to receive a second bone fastener; and
a second fixation device having a third opening configured to receive a third bone fastener, and a fourth opening configured to receive a fourth bone fastener;
wherein the first and third openings form a first pair of openings and the second and fourth openings form a second pair of openings;
the fixation devices arranged so that when first and third bone fasteners are at least partially inserted through the first pair of openings and into a first bone segment, and second and fourth bone fasteners are at least partially inserted through the second pair of openings and into a second bone segment, the first and second bone fixation devices are able to rotate relative to each other.

Abstract
An apparatus for use with bone fasteners comprises a first fixation device having a slot configured to receive a bone fastener, and a second fixation device having another slot configured to receive another bone fastener. The first and second fixation devices are interconnected for rotation relative to each other when the bone fasteners are in the slots. Summarized differently, an apparatus for use with bone fasteners comprises a first fixation device having a first pair of openings defining bone fastener locations, and a second fixation device having a second pair of openings defining bone fastener locations. The first and second fixation devices are interconnected for movement relative to each other such that the bone fastener locations defined by the first and second pairs of openings are located at four corners of a rectangular array.
