Abstract

Spinal cage devices, systems, and methods of assembly and implanting the devices and systems are disclosed. The cage system includes a cage and at least one locking screw assembly configured to couple to the cage. The spinal cage system includes a cage with a body portion, an external plate, and a rod. The body portion includes at least one opening positioned between the first and second ends, a center opening in the first end, and at least one hole adjacent the center opening. The external plate includes an opening and at least two holes on opposite sides of the opening. The rod extends through the center opening in the cage, the first end configured to couple to the external plate, and the second end positioned in the at least one opening. Methods for assembling a spinal cage system and for implanting a cage system are also disclosed.

Dependent claims

A spinal cage system comprising:

a cage;
said cage includes a body;
said body includes a body cavity opening and a cage rod opening;
said body cavity opening is positioned in a central region in said body;
said body cavity opening opens to at least one exterior surface of said body of said cage;
a rod;
an external plate;
said external plate includes an external plate rod opening;
a first connection arrangement;
and
an internal plate;
said internal plate includes an internal plate rod opening;
and
wherein at least a portion of said external plate is configured to be positioned on or near an external surface of said body of said cage;
and
wherein a portion of said rod is configured to be positioned in said cage rod opening in said body of said cage such that at least a portion of a first end portion of said rod extends outwardly from said external surface of said body of said cage;
and
wherein at least a portion of said internal plate is configured to be positioned in said body cavity opening of said body of said cage;
and
wherein said first rod connection arrangement is configured to secure said external plate to said first end portion of said rod when said first end portion of said rod is at least partially positioned in said external plate rod opening and a portion of said rod is positioned in said cage rod opening in said body of said cage and said external plate is positioned on or near said exterior surface of said body of said cage;
and
wherein said internal plate is configured to be secured to said second end portion of said rod when said second end portion of said rod is at least partially positioned in said internal plate rod opening and a portion of said rod is positioned in said cage rod opening in said body of said cage and when at least a portion of said internal plate is positioned in said body cavity opening of said body of said cage.
