An expandable vertebral body implant, and methods of assembly and using the implant. The vertebral body implant includes a body with a first end and a second end, a rotating member rotatably coupled to the first end of the body, wherein an end includes a plurality of first notches inset into the rotating member, an extension member moveably coupled to the rotating member, and a locking member positioned on an interior of the body. Methods for assembling and using the vertebral body implant are also disclosed.

Expandable vertebral body replacement device and method

An expandable vertebral body device, system, instrument, and methods of assembly and using the device, system, and instrument are disclosed. The vertebral body device includes 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. The expandable cage system comprises a vertebral body device and an insertion instrument. Methods for assembling and using the vertebral body device and instrument are also disclosed.

The present invention provides expandable devices and insertion tools for deploying the expandable devices. The expandable devices are capable of increasing in height and width when expanded from a closed configuration to an open configuration to occupy a larger volume and to present a larger surface area. The expandable devices are lockable and are capable of rigidly occupying a space after expansion. In some embodiments, the expandable devices are useful as interbody devices for spinal fusions.
