Abstract
The present specification contemplates a spinal implant device that goes into, for example, a corpectomy defect in any part of the spine. In one aspect, the device is substantially tubular and is comprised of two hollow rods that coaxially slide on one another. The device can thus then expand in length and can be locked or fixed at a particular length. The device is hollow to configure a malleable trocar to be placed into the device. With this trocar, polymethymethacrylate (PMMA) can be injected and packed into the vertebral body cephlad and caudad. Finally the device can be locked at a desired length by crimping it or locking it using other fastening means.
