Management of basilar invagination: A historical perspective

Abhidha Shah, Elena Serchi

Research output: Contribution to journalArticlepeer-review


For a long time the terms basilar invagination and platybasia were used interchangeably. Basilar invagination has been defined as a prolapse of the vertebral column into the spinal cord. Platybasia is defined as an abnormal obtuse angle between the anterior skull base and the clivus. The authors review the existing literature and summarize the historical and modern perspectives in the management of basilar invagination. From radiological curiosities, the subject of basilar invagination is now viewed as eminently treatable. The more pronounced understanding of the subject has taken place in the last three decades when on the basis of understanding of the biomechanical subtleties the treatment paradigm has remarkably altered. From surgery that involved decompression of the region, stabilization and realignment now form the basis of treatment.
