Summary
C1-C2 pedicle screw fixation offers a viable alternative for patients unsuitable for transarticular screw fixation. This rigid fixation technique expands treatment options for complex spinal instability.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- Transarticular screw fixation of the C1-C2 complex is a standard method for achieving rigid fixation in unstable spines.
- Certain patient anatomies or vertebral artery positioning can preclude the use of transarticular screw fixation.
Observation:
- A novel rigid screw technique was employed for a patient excluded from transarticular C1-C2 screw fixation.
- The patient presented with C1-C2 complex instability requiring surgical stabilization.
Findings:
- C1-C2 pedicle screw fixation was successfully implemented using a fixed moment arm cantilever beam system.
- This method achieved immediate and rigid fixation of the C1-C2 complex.
Implications:
- This pedicle screw fixation technique is technically more adaptable than transarticular screw fixation.
- It broadens the applicability of rigid C1-C2 fixation to a wider patient population.
