Occipito Vertebral Fusion of the Atlanto-Axial Dislocation and Basilar Impression

Abstract

Four patients with the congenital atlanto-axial dislocation or basilar impresion were received the decompression and the occipito vertebral fusion. These patients have either or both of the neurological and circulatory disturbance. Two patients were recieved the decompression and the posterior fusion with the bone graft and wiring. Other two patients were received the decompression and the posterior fusion with the bone graft, wiring and acrylic fixation. One of these patients was failed because of the absorption of bone graft and the rupture of wiring, but others showed good fixation.
