was changed:
Anterior subluxation of cervical spine (also known as hyperflexion sprain) is a ligamentous injury to the cervical spine.
Clinical presentation
Patient presents with neck pain. There may be symptoms due to spinal cord oedema.
Pathology
It results from ligamentous injury, however, there may be associated wedge fracture.
Radiographic features
RadiographPlain radiograph
- may be normal
- focal kyphosis at the site of ligament disruption
- helps differentiating the condition from diffuse reversal of cervical lordosis
- increased interspinous distance
- concerned disc space shows reduced height anteriorly and increased height posteriorly
-
in few casesmild anterolisthesis may be noted
CT
CT shows the findings of radiograph in more detail.
MRI
MRI can demonstrate disruption of ligaments, including posterior longitudinal ligament, ligamentum flavum and interspinous ligaments.
- soft tissue oedema is usually present: commonly in interspinous space
- spinal cord oedema may be seen: usually result from traumatic disc herniation rather than compression by the bone
