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%.

Abstract Objective To review the management of atlanto-axial instability by means of posterior transarticular screw fixation with specific reference to intraand postoperative complications and rates of fusion. Method Clinical records and X-rays of 22 consecutive patients were reviewed. Rheumatoid arthritis was the aetiology in six patients, ankylosing spondylitis in one and the rest post-trauma...
متن کاملDiagnosis of acute atlanto-axial rotatory fixation.
We report three cases of atlanto-axial rotatory fixation in adults. Early diagnosis was made by clinical tests showing restricted head rotation in maximal neck flexion and asymmetry of the transverse processes of the atlas, confirmed by cineradiography. Early treatment by traction may obviate long-term problems of torticollis and instability.
متن کاملAtlanto-axial fusion: Magerl transarticular versus Harms instrumentation techniques
Atlanto-axial instability may occur following indirect trauma resulting in transverse ligament disruption or dens fracture. It may also occur insidiously in inflammatory conditions such as rheumatoid arthritis with progressive attenuation of the transverse ligament. Less frequently it may be associated with dysplasias such as achondroplasia, Down’s syndrome with a small dens or mucopolysacchari...
متن کاملBiomechanical 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...
