Atlanto-axial dislocations

Traumatic atlanto-axial subluxation.

Traumatic atlanto-axial subluxation is a rare injury which may not be revealed on routine radiographs, especially when there is muscle spasm. We report on seven patients with atlanto-axial subluxation as a result of neck injury; only two of them had significant head injuries. Three patients presented with a neurological deficit attributable to the injury, one immediate and two with delayed onse...

Congenital atlanto-axial dislocation.

Atlanto-axial dislocation IS an uncommon condition. It is usually secondary to trauma, infection (tuberculous and non-tuberculous atlas and axis) and rheumatoid arthritis. Other uncommon causes reported include retropharyngeal abscess, malignant deposits, ankylosing spondylitis (Sorin, et al, 1979). Congenital atlanto-axial dislocation is rare. Wadia (1967) first drew attention to its relative ...

Establishment and evaluation of a prognostic model for surgical outcomes of patients with atlanto-axial dislocations

Objective Atlanto-axial dislocations (AADs) are potentially fatal disturbances with high spinal cord compression syndrome. As surgeons are still uncertain who is likely to benefit the most from surgery, a prediction tool is needed to provide decision-making support. Methods The model was established based on 108 patients with AADs using multiple binary logistic regression analysis and evaluated...
