Fracture without dislocation on the base of the dens axis. The atlanto-dental distance is not widened. In the atlanto-axial joint there is a ventral dislocation both sides.
Case Discussion
This is a type II fracture based on the Anderson and D'Alonzo classification.
Normally, the atlanto-dental distance can not more than 3 mm. In this case this distance is especially narrowed.
Even though this is an unstable fracture, the therapy was conservative.
Unable to process the form. Check for errors and try again.
