Computerized 3D reconstruction of the male occipito-atlanto-axial joints and the adjacent structures

Objective To build digitized visible model of the male occipito atlanto axial joints of the Chinese visible human to provide morphological data for image diagnosis and operation of the occipito atlanto axial joints. Methods Data of the cross sectional images of the fresh tissues from the Chinese visible human dataset were reviewed. Three dimensional computerized reconstruction of the occipito atlanto axial joints and the surrounding structures were generated from these data using an SGI workstation and imaging softwares. Results The digitized visible model of the male occipito atlanto axial joints could clearly display the structures of the occipito atlanto axial joints, especially the 3D anatomical relationship between the ligaments of the occipito atlanto axial joints, blood vessels, and bone structures. The 3D reconstruction could display the ligaments of the occipito atlanto axial joints independently and jointly. Any diameter of the structures reconstructed could be measured at any angle conveniently. Conclusion The Chinese visible human dataset provides complete and accurate data. The digitized model offers unique insights into the anatomy of the occipito atlanto axial joints, and can be used for the surgical teaching of the occipito atlanto axial joints and the design of the new surgical approaches.
