C1C2 Distraction and Compression Technique for Craniovertebral Junction Anomalies with Basilar Invagination and Irreducible Atlantoaxial Dislocation
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 CRANBERRY 500MG principles of the reduction achieved in all the planes by C1C2 screw placement, the cage insertion in the C1C2 joint, and manipula
