Abstract

Congenital atlantoaxial dislocation (CAAD) presented at variable age, Factors that determining this variability remain obscure. The orientation of these facets disrupted in congenitally deformed joints and this may be the reason for progressive slip and then irreducibility in CAAD Aims and objective. The aim of the current study was to review the specific anatomical and morphological features of the C1-C2 joint orientation and to add to existing knowledge by documenting their anatomical variability Materials and method: this is a prospective as well as retrospective , observational study conducted on patients with congenital atlantoaxial dislocation irrespective of age admitted in the department of Neurosurgery at the G. R. Medical College &J.A. Group of Hospitals, Gwalior(M.P.) Result & Conclusion: patients of AAD concluded that bony and vascular anomalies are more common in patients with irreducible AAD as compared to reducible one, thereby making surgery more challenging. Preoperative detection of irreducible AAD must make the surgeon aware of difficulties and to be prepared for that.
