The present invention relates to a system and a method for planning pedicle screw fixation and, more specifically, to a system and a method for planning the length, insertion path, etc. of a pedicle screw on the basis of a C-arm image. The system for planning pedicle screw fixation of the present invention comprises: a C-arm for taking an image of the spine of a patient; an insertion path provision unit for providing an entry point and insertion endpoint of a pedicle screw, on a C-arm image; a registration unit for calculating the spatial coordinates of the entry point and insertion endpoint on the basis of a reference coordinate system; a guide device which determines an insertion position of the pedicle screw on the basis of the spatial coordinates of the entry point and insertion endpoint, and which guides insertion of a probe towards the entry point according to the insertion position; and a screw determination unit which determines a length condition of the pedicle screw by acquiring the coordinates of a
