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 translational instability, canal stenosis
requiring decompressive laminectomy and defective C1 posterior arch.
The author reports three cases of complicated Os odonoideum(one cases of failed
occipito-C3 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 experience, it is postulated that C1/2 transarticular screw
fixation seems to be superior to other methods in stabilization and fusion for
complicated Os-odontoideum.
