Summary
Transarticular C1-2 fixation provides excellent stability for atlantoaxial instability, achieving an 87.3% fusion rate at 12 months. This multicentric study confirms its effectiveness with acceptable complication risks.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Fusion Techniques
Context:
- Atlantoaxial instability presents significant challenges in spinal surgery.
- Transarticular C1-2 fixation is a recognized surgical option for managing this condition.
- Multicenter data are crucial for objective evaluation due to small, disparate institutional patient groups.
Purpose:
- To objectively compare the outcomes of transarticular C1-2 fixation across multiple institutions.
- To evaluate the efficacy and safety of this surgical technique in a larger patient cohort.
Summary:
- A 9-year retrospective study analyzed 80 patients undergoing transarticular C1-2 fixation for various causes of atlantoaxial instability.
- Optimal screw placement was achieved in 68.7% of cases, with a 12-month fusion rate of 87.3%. Segmental stability was maintained in all patients.
- Complications included vertebral artery injury (5%) and wound dehiscence (3.7%), with most events having no significant clinical sequelae.
Impact:
- This study validates transarticular C1-2 fixation as a highly stable and effective treatment for craniocervical and upper cervical spine instability.
- Findings support the procedure's high fusion rates and immediate stability, comparable to existing literature.
- The data underscore the importance of respecting anatomical variations to minimize procedural risks, particularly vertebral artery injury.
