Safety Issues and Neurological Improvement following C1 C2 Fusion using C1 Lateral Mass and C2 Pedicle Screw in Atlantoaxial Instability

The evolution of instrumentation methods for C1 C2 fusion from the use of posterior wiring methods to transarticular screws and C1 lateral mass with C2 pedicle screw construct have improved fusion rates to almost 100%. However, the C1 lateral mass and C2 pedicle screw technique is technically demanding. This is a prospective review of a series of ten patients who was planned for C1 C2 fusion using C1 lateral mass and C2 pedicle screw technique between January 2007 and June 2009. The procedure was converted
