摘要:
Improved methods and apparatuses for vertebral body distraction and fusion in accordance with various embodiments of the present invention employ flexure members. Flexure members connect a plurality of structural members to end plates on one end and blocks on another end. Upon insertion into the disc space, a drive screw or similar mechanism can be actuated to drive expansion blocks closer together, which causes flexure members to deflect, resulting in expansion of the structural members and distraction of the end plates. The distracted device can then remain in the body and be used for vertebral body fusion.
