Summary
Transarticular screw fixation for C1-C2 joint instability is a safe and effective surgical technique. This method demonstrates high fusion rates and minimal complications, offering a reliable treatment for cervical spine disorders.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- Atlantoaxial instability is a common complication in various spinal disorders.
- Transarticular screw fixation of the C1-C2 joint is a proposed biomechanically superior treatment.
- This study evaluates the clinical outcomes of this fixation technique.
Purpose of the Study:
- To assess the safety and efficacy of transarticular screw fixation for C1-C2 joint instability.
- To report the surgical experience and outcomes in a cohort of patients.
Main Methods:
- Retrospective analysis of 23 patients undergoing C1-C2 transarticular screw fixation.
- Mean follow-up duration of 39.5 months.
- Evaluation of complications, screw positioning, and osseous fusion.
Main Results:
- Mean hospitalization was 3.4 days; no intraoperative or early postoperative complications.
- Satisfactory screw positioning in 91.3% of patients; 82.6% achieved solid osseous fusion.
- Four patients (17.4%) experienced unrelated postoperative complications; no reoperations were needed for suboptimal screw placement.
Conclusions:
- Transarticular C1-C2 screw fixation is a safe and reliable surgical technique.
- Continued refinement of technique and application criteria enhances its therapeutic potential.
- This method offers a versatile treatment option for atlantoaxial instability.
