| Abstract: | In order to understand the role of the alar ligaments in limiting 3D movements of the occipito-atianto-axial complex, fresh cadaveric specimens of occiput (CO) to C3 were subjected to 1.53 Nm pure moment which caused physiological 3D movements of the complex. The experiment confinned that the alar ligaments also limit contralateral bending of occipito-atianto-axial complex and flexion of CO-C1 joint. Functional loss of the alar ligaments indicates a potential for rotatory instability of the occipito-atianto-axial complex, which should be considered in conjunction with the clinical signs. |
