A pedicle augmenter is provided for reconstruction of a vertebra subject to loss of bone mass or fracture, and is to be planted into the vertebra from a pedicle of the vertebra for helping maintain or restore normal position and size of the vertebra. Through the vertebral pedicle, a device, fit the pedicle anatomy, was created to reconstruct the fractured or collapsed vertebral body. The device is a rectangular solid with smooth edge and the first-end was with ellipsoid shape. The device has porous surface. The internal screw file for the instrument connection was createdfrom a second-end towars to a first-end. The fractured body was reduced and maintained by such device until the bone growth and fracture union.
