Abstract: A bone cage placement device used to insert and position a bone cage in the disc space. Once the bone cage is positioned, a selector tool is inserted into the center aperture of the bone cage placement device. The end of the selector tool has a cam lift driving feature which is used to rotate the cam lift of the bone cage and expand the bone cage to the desired height. The selector tool is removed, and a graft placement tool and plunger are used to insert bone graft material into the plug. An end plug installation tool and installer are then used to insert an end plug to prevent leakage of material from the bone cage. The bone cage is released from the bone cage placement device, which is then removed from the patient's body.

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.

Abstract: The present invention is an expandable and adjustable bone cage designed to be used in conjunction with a pedicle screw or plating fusion system. The expandable and adjustable bone cage provides structure for the placement of bone graft material between two adjacent vertebral bodies in order to stabilize or fuse the spine in a predetermined position. The expandable and adjustable bone cage is contoured for easy insertion between vertebral bodies and may be expanded after insertion to maintain, establish or increase lordosis, as well as help secure the bone cage.
