Techniques of posterior C1-C2 stabilization.

摘要: Instability of the atlantoaxial complex may result from inflammatory, traumatic, congenital, neoplastic, or degenerative disorders and often requires surgical stabilization. Initial dorsal wiring techniques allow safe fixation but require rigid external immobilization have been associated with high fusion failure rates. Rigid screw including transarticular C1-C2 rod-cantilever offer higher rates less need for are more technically demanding. using crossing C2 laminar screws offers without technical demands pars placement. The history reviewed, success complications each discussed.
