The dorsal approach for reposition and stabilisation of dorsal and lumbal spine fractures is widely accepted. It is much easier for the surgeon and with lower risk for the patient. For placement of the pedicle screws 3 steps with X-ray fluoroscopy in transversal and anteroposterior direction are necessary: K-wire placement in the pedicle, drill for opening the pedicle and finally screw placement. With the use of two fluoroscopes and a central cannulated drill which is placed over the K-wire the operation gets much shorter, easier and the fluoroscopy time can be reduced significantly.
