Spondylolisthesis
Understanding a slipped vertebra and how stability and nerve symptoms guide treatment.
Request My ConsultationUnderstanding spondylolisthesis
Spondylolisthesis occurs when one vertebra slips relative to the bone below it. This is different from a slipped or herniated disc. Some slips cause no symptoms; others are associated with back pain or narrowing around spinal nerves.
Common symptoms
- Lower-back aching or discomfort with activity.
- Leg pain, numbness, or weakness when nerves are affected.
- Difficulty standing or walking for long periods, sometimes eased by sitting.
What can cause it?
Degenerative changes in discs and joints can allow a vertebra to move forward. Another form involves a defect or stress fracture in a small bony bridge called the pars. The cause and degree of movement influence evaluation.
How it is evaluated
Standing X-rays show vertebral alignment. Flexion and extension views may be used to assess movement, while MRI can show nerve compression. The slip measurement is considered together with symptoms and neurological findings.
Treatment considerations
These are general educational options. A consultation helps determine what is appropriate for your diagnosis and health.

- Is my slip stable, and does it explain my symptoms?
- If surgery is considered, why would decompression alone or decompression with fusion be appropriate?
