Anterior placement of a screw for fixation of an odontoid fracture is performed to maintain axial rotation at the C1, C2 level. This morphometric study was performed to determine the length of anterior odontoid screw trajectory in adult Turkish population. Measurement of the trajectory length was performed on midsagittal T1-W sequence of MRI. Overall average length is 3.52±0.81 cm. Commonly used 35 mm screws are suitable for approximately half of the population.
