Abstract:
Fractures of the second cervical vertebra with involvement of the odontoid process can mostly be treated conservatively by immobilization. In the case of high-grade unstable fractures and pseudarthrosis dorsal C1/2 spondylodesis should be considered.Based on established atlantoaxial osteosynthesis techniques for dorsal C1/2 spondylodesis, a polyaxial screw-rod system with C1/2 transarticular screws connected with C1 lateral mass screws was carried out in a 56-year-old male patient with dislocated odontoid fracture.No intraoperative or postoperative complications occurred. During a follow-up of 36 months there was no screw loosening or dislocation.The presented alternative technique of dorsal C1/2 spondylodesis is a safe and effective method for stabilizing the atlantoaxial movement segment in cases of posttraumatic instability.

Self-Locking Screw
A square-threaded screw jack carrying a load is considered self-locking if the screw retains its position even after the moment applied to it is removed.
Frictional Forces on Screws
A jack with a square-threaded screw is a mechanical device used to lift heavy loads by applying a force at its handle. When the force is applied, the screw turns, raising the load. The screw can...
