title: [Revision strategy after failure of Magerl-Gallie fusion procedure].
abstract: For failure of an implant after a Magerl-Gallie stabilization procedure and detection of pseudarthrosis with instability of segments C1 and C2, operative revision and restabilization are necessary in the majority of cases. The following case report summarizes a revision strategy using a modified Goel-Harms procedure to restabilize a persisting C1-C2 instability after a failed Magerl-Gallie fusion procedure. This was necessary because of breakage of both transarticular C1-C2 screws with incompletely consolidated atlanto-axial fusion and persisting C1-C2 instability.
