Corpectomy device comprising outer component, inner component and riser. The outer component includes a first endplate and first structure. The first structure includes a window and seat in communication with the window. The seat defines an opening to be pre-packed substantially with first grafting material. The inner component includes a second endplate and second structure at least partially disposed in the first structure in a first configuration. The second structure is to be pre-packed substantially with second grafting material. The riser has a third tubular structure to be received through the window into the seat to engage at least a portion of the second structure that extends the second structure into a second configuration with respect to the first structure. The third structure is to be pre-packed substantially with third grafting material such that first, second and third grafting material remain pre-packed substantially and in communication in the second configuration. |
