Locked-in Syndrome After Traumatic Atlantoaxial Subluxation: A Case Report

Abstract

Traumatic atlanto-axial subluxation is a rare and underdiagnosed condition due to its high rate – reported to be between 60 and 80% – of early mortality. Its diagnosis takes into account the trauma mechanism, precise analyses of the imaging tests and the clinical presentation of the patient. This article describes a rare presentation of atlanto-axial subluxation associated with craniocervical dislocation as a case of locked-in syndrome. Level of evidence V; Retrospective observational study – Case report.
