Abstract:
C1/2 posterior transarticular screw fixation has become an accepted method of rigid internal fixation for patients requiring posterior C1/2 fusion. Especially,Surgery for Os odontoideum can be troublesome due to its severe tranlational instability, canal stenosis requiring decompressive laminectomy and defective C1 posterior arch. The author reports three cases of complicated Os odontoideum(one case of failed occipito-C2 fusion, two cases requiring C1 laminectomy) with C1/2 transarticular screw fixation and interarticular bone fusion. All required decompressive laminectomy and demonstrated highly unstable translational instabilities. On the basis of these experiences, it is postulated that C1/2 transarticular screw fixation seems to be superior to other methods in stabilization and fusion for complicated Os-odontoideum.
