Abstract: A spinal implant device is provided comprising a body structure and a movable door coupled or configured to couple to the body structure. The spinal implant device can include a distal end, a proximal end, two opposing side walls extending between the distal end and the proximal end, an upper wall, a lower wall, and a central cavity. The movable door is configured to open to allow the central cavity to be packed with material and the movable door is configured to close. A method is provided comprising providing a spinal implant device, packing the cavity with the material, closing the movable door, and inserting the spinal implant device between adjacent vertebrae. A method of manufacturing a spinal implant device is provided comprising 3D printing a spinal implant device, wherein the spinal implant device is 3D printed as one piece.

Abstract: A spinal implant device is provided comprising a body structure with a central cavity and a movable lid configured to cover the central cavity. The movable lid is configured to be opened to pack a material in the central cavity. The movable lid can be connected to the body structure with a moveable joint. The spinal implant device can include a compressible feature. A method for treating the spine is provided comprising opening a movable lid of a spinal implant device, packing a material in a central cavity of a spinal implant device, closing the movable lid, and inserting the spinal implant device between vertebrae.
