Paragraph Number

141

The surgical device 200c may be used with a method for intraoperatively confirming a pedicle screw insertion trajectory on a vertebra of a patient. The method may start by positioning a patient on a table for a spinal surgery procedure such that a coronal plane of the patient is parallel to a floor supporting the table. Next, the surgical device 200c may be calibrated by positioning the surgical device 200c superficial to skin of the patient and substantially centering the surgical device 200c above the patient’s spine. Next, the surgical device 200c may be calibrated to set a reference axis for the hand-held surgical device relative to the patient’s spine. Next, a distal end 214 (e.g., bone probe 216) of the shaft 210 and/or surgical device 200c is placed on a surface of a pedicle of a vertebra of the patient’s spine.
