Atlanto-Axial Facet Joint Distraction Using Interfacet Cages for Basilar Invagination In Chiari Malformation
Abstract
Basilar invagination is defined by the upward migration of the odontoid process into the foramen magnum, leading to compression of the medulla oblongata at the cranio-cervical junction (CCJ). Here, we report the case of a 33-year-old patient with progressive basilar invagination. Surgical management consisted of atlanto-axial cage distraction, expansile duroplasty and posterior cervical fusion from C1 to C5. Atlanto-axial cage distraction is an effective strategy to realign the CCJ in cases of basilar invagination. Publication History Article published online: 27 February 2026 © 2026. Thieme.
