Abstract
A method for guiding symmetric implantation of bone screws is provided. The method includes the steps of: providing a spinal image of a spine, wherein the spine has a first bone screw implanted in one side of a spinous process of the spine; obtaining a first implanting information of the first bone screw; setting a reference line in the spinal image; generating a second implanting information by mirroring the first implanting information with respect to the reference line; and guiding a second bone screw to be implanted in the other side of the spinous process according to the second implanting information. The method generates a second implanting information that is based on and symmetric to the first implanting information, thus allowing the bone screws to be precisely implanted in both sides of the spinous process and aligned with each other in the same transverse section of the spinous process.
