摘    要:Objective To evaluate biomechanic stability of occipitoatlantoaxial reconstruction with different internal fixations. Methods Twelve fresh human cadaveric occipitocervical spine specimens were mounted in a spine-testing machine to record the three-dimensional angular movement at occiput OcC1 and C1,2. The specimens were tested under five different oonditions: the intact, the occipitoatlantoaxial instability, fixation with Ti-cable plus bone graft group (group A), fixation with the transarticular screw fixation (group B), fixation with SUMMIT occipitocervical spinal fixation system (group C).
