【Abstract】 AIM: To provide the anatomical basis for lateral arch screw fixation in C2 vertebra of Chinese. METHODS: Fiftyseven dry C2 vertebra of Chinese were measured. RESULTS: The parameters obtained of anterior portion of lateral arch were (including Left/Right): Medial inclination from superior view [ αs = (38±8)°/(40±8)°], superior inclination [γ= (63±9)°/(62±8)°], and the superior, middle and inferior width [bs = (±) mm/(±) mm, bm = ± mm/± mm. bi = (±) mm/(±) mm], height of superior articular process [dsa = (±) mm/(±) mm], superior and inferior height [hup=(±) mm/(±) mm, hip=(±) mm/(±) mm]. Other parameters were (including Left/Right ): Horizontal distance from standard screw entrance point (O) to lateral edge of inferior articular process [lla= (±) mm/(±) mm], posterior edge of superior articular process [los= (±) mm/(±) mm] and midposition of isthmus on superior aspect [loi = (±) mm /(±) mm], and vertical distance from O to inferior edge of inferior articular process [hia=(
±) mm/(±) mm]. bm in 26 (%)left and 27(%)right sides was less than mm. If set αs as medial inclination of lateral screw insertion, 36 left screws and 40 right ones would rate into the corresponding side of a
