Expandable vertebral body replacement device and method

An expandable cage system, comprising:

• a vertebral body device, comprising:
• a body with a first end and a second end, the body comprising:
• at least one aperture positioned on the body along a midpoint between the first end and the second end;
• at least one first locking hole positioned superior to the at least one aperture;
• and
• at least one second locking hole positioned inferior to the at least one aperture;
• a first rotating member coupled to the first end;
• a second rotating member coupled to the second end;
• a first extension member moveably coupled to the first end;
• and
• a second extension member moveably coupled to the second end;
• and
• an insertion instrument, wherein the insertion instrument is sized to be placed around the at least one aperture, the at least one first locking hole, and the at least one second locking hole.

A method of using an expandable cage system, comprising:

• obtaining a vertebral body implant, the vertebral body implant comprising:
• a body with a first end and a second end;
• a first rotating member rotatably coupled to the first end;
• a second rotating member rotatably coupled to the second end;
• a first extension member moveably coupled to the first end;
• and
• a second extension member moveably coupled to the second end;
• obtaining an insertion instrument;
• coupling the vertebral body implant to the insertion instrument;
• inserting the vertebral body implant into a patient between two vertebral bodies;
• expanding the vertebral body implant;
• and
• removing the insertion instrument.
