摘要：
A three-dimensional guide for a wire for forming a pedicle screw insertion hole is produced based on a CT image of a spine, and includes a contact surface section that comes in surface contact with a morphological surface of a bone at an insertion site, and a guide block section that is provided upright from the contact surface section. The guide block section has a guide hole that restricts the insertion direction of the wire. The guide hole has an inner diameter slightly larger than the outer diameter of the wire. The guide hole has a length of 15 to 30 mm to restrict the insertion position and the insertion direction of the wire.
