Background: The optimal surgical treatment of atlanto-axial instability rem
ains controversial despite the variety of modifications and supplemental te
chniques currently available. Methods: We describe a modification of the Br
ooks posterior wiring technique supplemented with transarticular screws for
C1-C2 instability. Results: This method has been implemented in 30 patient
s in our institution with no radiological failures. Conclusions: The modifi
cation provides several technical advantages and potentially stronger fixat
ion compared to methods currently in use.
