Expanding interbody implant and articulating inserter and method

摘要

A device to space vertebral members with first and second members that may have at least one ramped section. The first and second members may be positioned in a vertically overlapping arrangement with interior sides of the members facing together. The device may be positionable between a first orientation with the ramped section of the first member positioned away from the ramped section of the second member, and a second orientation with the ramped section of the first member positioned against the ramped section of the second member. The device may include a greater height measured between the exterior sides in the second orientation than in the first orientation.

1. A method of spacing vertebral members comprising the steps of:
placing a spacer between the vertebral members, the spacer being in a first orientation and having opposing exterior sides distanced at a first height; and moving a first ramped surface within the spacer along a second ramped surface within the spacer until the first ramped surface is spaced apart from the second ramped surface to move the spacer to a second orientation in which the opposing exterior sides are distanced a second height that is greater than the first height.
