Introduction: 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.
Methods: About 60 patients with CVJ Anomalies were taken for this prospective study. All the Congenital& 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 & 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 5mm showed 75% improvement after surgery.
Conclusion : The Atlantodental Interval is the important pre operative prognostic marker. The Craniometric lines are very arbitrary. No definite surgical technique is correlated with the post operative surgical outcome
