APPARATUS AND METHOD FOR SPINE FIXATION

摘要

A spine fixation assembly (100) connecting a first (92) and a second (94) vertebra includes first (112) and second (110) elongated plates that form an X-shaped structure (Figure 2A, Figure 6). The first elongated plate has a first (112a) and a second (112b) end that are attached to a first location of the first vertebra and to a second location of the second vertebra, respectively. The second elongated plate (110) has a first (110a) and a second (110b) end that are attached to a second location of the first vertebra and to a first location of the second vertebra, respectively. The ends of the plates are attached to the various locations of the vertebra via screws (120a, 120b, 122a and 122b) or hooks. The elongated plates may have adjustable length, may be rotated around a central axis passing through the center of the X-shaped structure and may be cross-coupled to each other via a screw. A third (114) and fourth (116) elongated plate may be attached horizontally across the top and bottom of the X-shaped structure, respectively.
