Abstract
The present invention is a rotatable cam lift. The distal end of the rotatable cam lift has a plurality of cam lift lobes and nesting surfaces that allow an expandable bone cage to be expanded with maximum control and predictability of expansion and which hold the bone cage firmly in position when expanded. Cam lift edges prevent over-rotation of the cam lift.
