Abstract

Atlanto-axial instability in children with Down syndrome(trisomy 21) has become a wel! Known entity and it has been reported frequently since it was first reported over 25 years ago. However, symtomatic atlanto-axial dislocation associated with cord compression is relatively rare and it had seldom been reported. We recently experienced a 14-year-old mongoloid female with progressive quadriparesis, who have no prior cervical inflammation and we detected atlanto-axial dislocation with ossculum terminale and cord compression through radiological evaluations. We report a case of symptomatic atlanto-axial dislocation in Down syndrome with review.
