retrolisthesis

The term retrolisthesis (less commonly known as retrospondylolisthesis or posterolisthesis) refers to posterior displacement of a vertebral body relative to the caudal vertebral body.

Pathology

Causes include:

• trauma
• facet joint osteoarthritis
• congenital anomalies: e.g. pedicle underdevelopment

Radiographic features

Lateral spinal radiographs are able to characterize spinal alignment, including the presence of retrolisthesis. MRI has a role in assessing any consequent neurological compression due to resultant foraminal stenosis or spinal canal stenosis.
