Abstract

Objective: This study aimed to describe and evaluate the anatomical characteristics of the upper cervical spine on multi-detector computed tomography scans in adult Vietnamese individuals. Materials and Methods: A retrospective cross-sectional descriptive study on 288 cervical computed tomography scans of adults at Viet Duc University Hospital. Results: The mean dimensions of the posterior arch of C1 in terms of width, length, and height were 12,0±2,7mm, 20,9±1,9mm, và 6,4±1,9mm, respectively. The lateral mass of C1 had an average width, length, and height of 9,8±1,5mm, 28,1±2,2mm, và 14,6±1,9mm, respectively. The C2 pedicle had mean dimensions of 6,3±1,6mm in width, 31,2±3,0mm in length, 10,0±1,2mm in height, and a pedicle angle of 38,0°±5,8°. The mean dimensions of the C2 lamina were 5,9±1,3mm in width, 32,7 ± 3,4mm in length, 12,8±1,9mm in height, and a laminar angle of 48,2°±3,8°. Conclusion: The study confirms that the anatomical characteristics of the C1–C2 spine are similar to those of Asian populations, but show significant differences when compared to European populations. Notable anatomical variations were observed between sexes and between the left and right sides. The results of this study help optimize surgical technique selection, improving safety and effectiveness.
