<p>The present invention enables, with a simple structure and without increasing the diameter of the device, a space inside a vertebral bone to be filled with a filler material while preventing leakage through cracks formed in the vertebral bone by compression fractures or the like, thereby reducing the length of time required for treatment. The present invention provides a device for vertebral repair used in procedures to repair vertebral fractures, comprising a pipe-like tubular body that is inserted into an introduction hole formed in a vertebral arch pedicle and can fill the vertebral bone interior with a filler material through an internal through-hole, and a sheet member attached in a folded state to the front end of the tubular body so as to obstruct the opening at the front end, wherein the sheet member is attached in such a manner as to separate from the tubular body when subjected to a compressive force from the filler material introduced through the through-hole in the tubular body.
