Abstract

The authors describe four cases of basilar invagination (BI) with irreducible atlantoaxial dislocation (AAD) by distraction and compression technique. The article describes the technique in detail and the principles of the reduction achieved in all the planes by C1C2 screw placement, the cage insertion in the C1C2 joint, and manipulation of the joint. They described in the literature well-discussed various modifications and their application for treatment of BI with irreducible AAD.
