Subaxial sagittal alignment and adjacent-segment degeneration after atlantoaxial fixation performed using C-1 lateral mass and C-2 pedicle screws or transarticular screws

, 2010
Object The purpose of this study was to evaluate the effect of a fixed atlantoaxial angle on subaxial sagittal alignment, and that of atlantoaxial fixation on adjacent-segment motion and degeneration.

Rotary fixation of the atlantoaxial joint.

JBR-BTR : organe de la Societe royale belge de radiologie (SRBR) = orgaan van de Koninklijke Belgische Vereniging voor Radiologie (KBVR), 2004
Rotary fixation of the atlanto-axial joint is a rare disorder in which the atlas gets fixed in a position normally achieved during rotation. A persistent asymmetrical position of the dens in relation to the atlas during head rotation is the clue to the diagnosis. Rotary fixation can be demonstrated by radiography/fluoroscopy and computed tomography (CT)
