A Comprehensive Study on Craniovertebral Junction Anomalies

Objective: To analyze comprehensively about the incidence of craniovertebral junction anomalies in different age groups, their sex prevalence, their clinical findings, radiological abnormalities, the different surgical procedures done and their outcome.

Materials and Methods: About 60 patients with CVJ anomalies were taken for this prospective study. All the congenital and acquired CVJ anomalies in all the sex groups were taken for the study. The incidental Arnold-Chiari malformation was excluded from this study. All the personal, clinical, radiological, and surgical treatments and the outcomes were entered and analyzed.

Results: The CVJ anomalies are more common in young adults almost equal in both sexes. The congenital (66.6%) are more common than the acquired. Atlantoaxial dislocation (21.6%) is the most common congenital bony anomaly and Arnold-Chiari malformation is the most common soft tissue anomaly. The patients with increased ADI 3 to 5 mm showed 75% improvement after surgery.

Conclusion: The atlantodental interval is the important preoperative prognostic marker. The craniometric lines are very arbitrary. No definite surgical technique is correlated with the postoperative surgical outcome.
