Various surgical instruments for use in the treatment of vertebral body compression fractures, used respectively for: widening a working path; reducing deformity; inserting a filler; and impacting a filler are provided. A set of surgical instruments including these instruments makes it possible to treat collapsed vertebral bodies easily and reliably are provided. The set includes a guide rod 1 (an instrument for widening a working path), a vertical elevator 2 (an instrument for reducing deformity), a horizontal elevator 3 (an instrument for reducing deformity), an inserter 4 (an instrument for inserting a filler), and an impactor 5 (an instrument for impacting a filler). The guide rod 1 is used for widening a path 93 formed in a collapsed vertebral body 91. The vertical elevator 2 is used for returning the upper anterior portion of the collapsed vertebral body 91 to a substantially original shape. The horizontal elevator 3 is used for returning the upper middle portion of the collapsed vertebral body 91 to a substantially original shape. The inserter 4 is used for inserting a filler into the reduced vertebral body 91. The impactor 5 is used for increasing the density of the filler inserted into the reduced vertebral body 91.
