Transarticular C1-C2 screw fixation, first described by Magerl, is a widely accepted used technique for C1-C2 instability with a good biomechanical stability and fusion rate. We present a 69-year-old woman, who was diagnosed with a C2 Odontoid fracture type III and primarily treated with conservative treatment and collar. During first 2 weeks of follow-up, the patient developed cervical pain associated with C1-C2 instability. A minimally invasive posterior C1-C2 transarticular screw instrumentation with a percutaneus approach was performed. Minimally invasive approach with tubular transmuscular approach for C1-C2 transarticular screws instrumentation is safe and effective for C1-C2 instability.
