Atlantoaxial pseudoarthrosis. a Right lateral radiograph of the cervical spine showing pseudoarthrosis at C1-C2 and osteophyte formation between the dorsal neural arch of the atlas and the spinous process of the atlas in case 1. b Transverse computed tomography of the cervical spine revealing proliferative changes encroaching the vertebral canal in case 7. c Mid-sagittal T2W image of the cervical spine revealed cervical vertebral canal stenosis both dorsally and ventrally. The spinal cord was severely compressed at the C1-C2 level, and it was possible to identify arthrosis and beak osteophyte projecting into the vertebral canal. d Right lateral post-operative radiograph revealing satisfactory implant positioning. E) Mid-sagittal computed tomography of the cervical spine showing the partial odontoidectomy, ventral atlantoaxial stabilisation and significant reduction in the dorsal spinal cord compression
