C2–C3 spinal fracture subluxation with ligamentous and vascular injury . . . We present the case of a 29-year-old polytrauma patient with an unstable C2–C3 fracture subluxation secondary to hyperextension and rotation injury with complete ligamentous dissociation and vertebral artery dissection after a high-velocity injury
AO Spine upper cervical injuries classification system Type C injuries are any injuries that lead to a displacement between C2 and C3 This is the most severe type of hangman fracture with or without dislocation of the facet joints
Upper Cervical Spine Injury – C1 and C2 Fractures A catastrophic injury characterized by disruption of the tectorial membrane, alar, and transverse ligaments, leading to separation between the skull base and upper cervical spine
Cervical Spine Fractures • LITFL • CCC Trauma bilateral fracture of the posterior arch of C2 and disruption of the C2-3 junction neurological injury may result from damage to the posterior longitudinal ligament allowing significant anterior displacement of C2 on C3
Cervical injury - The Radiology Assistant Atlanto-occipital dislocation is an uncommon injury characterized by complete disruption of all ligaments between occiput and atlas with subluxation or complete dislocation of the occipitoatlantal factes
Spinal Trauma Specific Injuries - OrthoPaedia This mechanism of injury can also cause rupture of the transverse ligament which normally prevents the atlas from slipping forward relative to the axis In cases where the transverse ligament is ruptured, surgical arthrodesis (fusion) of C1 to C2 is indicated
