Retrolisthesis

Retrolisthesis is backward displacement of one vertebra relative to the vertebra immediately below it. This imaging finding may accompany disc degeneration or trauma. Its significance depends on stability, symptoms and whether associated changes are compressing a nerve or the spinal cord.

Interpreting an alignment finding

The term describes position rather than automatically identifying a pain source. Loss of disc height and joint changes can alter alignment. A small stable displacement has a different meaning from a new displacement after trauma or a segment with demonstrated mechanical instability.

Manifestations and warning signs

Some people have no symptoms. Others develop low back pain or leg pain when associated abnormalities compress a nerve root. New urinary retention, saddle numbness or loss of bladder or bowel control requires immediate emergency assessment. Rapidly progressive weakness also requires immediate emergency assessment; slowly progressive weakness warrants prompt medical evaluation.

Diagnosis

Examination compares pain, daily abilities and neurological findings with imaging. Standing radiographs, sometimes appropriately prescribed movement views, assess alignment. MRI is useful when nerve compression is suspected. Disc herniation, spinal stenosis and hip disorders are among the alternative explanations considered during assessment.

Treatment and outlook

Treatment addresses the clinical problem through continued activity, progressive exercise and individualized pain management. Surgery is considered for selected documented compression or instability, not for the word retrolisthesis alone. Studies of patients undergoing disc surgery cannot predict the course of every incidental imaging finding.

Role of TAGMED care

TAGMED may support a functional programme after instability and urgent conditions have been excluded. Treatment should not promise permanent vertebral repositioning through manipulation. NICE advises against traction for low back pain with or without sciatica; motorized decompression is a form of traction.

Frequently asked questions

Is this a forward slip?

No. Retrolisthesis describes backward displacement.

Is it always painful?

No. It may be an incidental, asymptomatic finding.

Do a few millimetres require surgery?

No. Stability and clinical effects matter more than the report wording alone.

Must the image change for symptoms to improve?

Not necessarily. Pain and function can improve without visible realignment.

Can walking continue?

Often yes, with suitable adjustment, unless trauma or new neurological warning signs require assessment first.
