1. A method of percutaneous spinal surgery comprising the steps of:

  • scanning a patient by computed tomography, and producing an image of the patient in a transverse plane;

    determining, on said image, a desired path for insertion of a guide pin;

    measuring, on said image, the lateral distance from the patient'"'"'s midline to the point at which said path intersects the skin of the patient'"'"'s back;

    by viewing the patient'"'"'s spine radiographically in the anterior-posterior direction, marking the skin of the patient'"'"'s back directly over the midline, and marking the skin of the patient'"'"'s back with a line extending transverse to the patient'"'"'s midline in a plane corresponding to said transverse plane; and

    thereafter, establishing an insertion point on the patient'"'"'s back, on the transverse line, at a distance equal to the lateral distance measured on said image.
