The mainstream screw placement method is still the auxiliary free-hand experience screw placement during C-arm surgery. Due to the stenosis of the upper cervical spinal canal and the thin pedicle (about 3-4mm in diameter), it is close to the vertebral artery and spinal nerve, especially the high span of the vertebral artery malformation. For patients, there is only one chance for nail placement. Experienced nail placement is very easy to damage nerves and blood vessels, resulting in sensory and motor disorders of the limbs, paralysis, cerebral infarction, and even life-threatening situations. Statistical analysis is very rich in the experience of spine surgeons. The success rate of bare-handed nail placement is 84%-86%, effectively improving the success rate of screw placement and reducing the incidence of surgical complications are the problems that spine surgeons urgently need to solve.
