A cervical C1–C2 fixation system is an advanced spinal instrumentation system specifically developed for stabilizing the atlantoaxial region, which includes the first cervical vertebra (C1 – atlas) and the second cervical vertebra (C2 – axis). This region is highly mobile and critical for head rotation, making stable fixation essential in cases of instability or injury.

The system typically includes C1 lateral mass screws, C2 pedicle or pars screws, rods, and connectors, which work together to create a rigid construct. These components are connected using rods to immobilize the C1–C2 segment, promoting bone fusion and restoring proper alignment.

Manufactured from medical-grade titanium or titanium alloy, the system ensures high strength, fatigue resistance, and excellent biocompatibility. The design allows for precise screw placement and secure rod fixation, providing immediate stability and long-term durability.

C1–C2 systems are widely used in treating atlantoaxial instability, odontoid fractures, congenital abnormalities, rheumatoid arthritis involvement, and trauma, where reliable fixation and fusion are critical to protect the spinal cord and restore function.
