Range of cervical rotation after posterior atlanto-axial fusion.

Biomechanical Comparison of Five Different Atlanto-axial Posterior Cervical Fixation

Introduction: Previous investigations have demonstrated that threepoint fixation, using bilateral transarticular screws in combination with posterior wiring, provide the most effective resistance to minimize motion about C1-C2. However, transarticular screws are technically demanding and require considerable experience. Posterior wiring techniques affording one point of fixation, such as Brooks...

Transoral decompression and posterior fusion for rheumatoid atlanto-axial subluxation.

Cervical myelopathy is an uncommon but potentially fatal complication of rheumatoid atlanto-axial subluxation. Computerised myelotomography with three-dimensional reconstruction shows that rheumatoid pannus, together with the odontoid peg, contributes significantly to anterior cervico-medullary compression. These findings were the basis for treatment by transoral anterior decompression and post...

Atlanto-axial fusion with transarticular screw fixation.

We reviewed 161 patients, from four centres in Switzerland, who had undergone posterior fusion of the upper cervical spine with transarticular screw fixation of the atlanto-axial joints. They were followed up for a mean 24.6 months. The vertebral artery and the medulla escaped injury and only 5.9% of the complications were directly related to the screws. The rate of pseudarthrosis was 0.6%.
