A pedicle augmenter is provided for reconstruction of a vertebra subjected 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 pedicle, a device, fit the pedicle anatomy, was created to reconstruct the fractured or collapsed vertebral body. The device has a rectangular bar-shape, and has a first end, a second end, four sides, a recess on the second end, and a screw hole lengthwise formed on the second end; each of the four sides has a sloping portion near to the first end; the four sides of the body augmenter have cavities on other portions thereof, which cavities communicate with each other to form a hollow area together. The fractured body was reduced and maintained by such device until the bone growth and fracture union.
