Distraction, Compression, and Extension Reduction of Basilar Invagination and Atlantoaxial Dislocation

Abstract

Distractive compressive extension and reduction of BI and AAD seems to be an effective and safe method of treatment. It is different from the earlier described techniques, because it is the first procedure that uses a spacer not, only for distraction, but also as a pivot to perform extension to reduce the AAD.
