What is the difference between spondylosis and spondylolisthesis?
Spondylosis is general spinal arthritis. Spondylolisthesis is the slippage of one vertebra forward over the one below it. This slippage can cause instability and pinch nerves.

What is Spondylolisthesis?
Spondylolisthesis occurs when one vertebra slips forward over the one beneath it, typically in the lower back. This misalignment can lead to mechanical instability and significant nerve compression.
The condition can result from degenerative changes, stress fractures (common in athletes), or trauma. At Mountain Spine & Orthopedics, we use standing flexion-extension X-rays to grade the slippage and determine the best path to stability.
Common Symptoms of Spondylolisthesis
Patients with spondylolisthesis often experience:
What does the grade of my spondylolisthesis actually mean?
Grading measures how far one vertebra has slipped forward on the one below, in quarters of the vertebra's width: Grade I is up to 25%, Grade II up to 50%, and so on. Most adult degenerative slips are Grade I or II - and a low grade that has been stable for years is common, manageable, and often found incidentally.
Two things matter more than the grade alone. First, stability: standing and flexion-extension X-rays show whether the slip moves when you do, because a mobile slip explains mechanical pain that a static image cannot. Second, what the slip is doing to the nerves: as the vertebra shifts, it drags the exit doorways narrow and can produce foraminal stenosis and leg symptoms. A stable, low-grade slip with back pain is treated very differently from a mobile slip with progressive nerve compression - which is why the imaging workup is designed around motion, not just a single picture.
Causes and Risk Factors of Spondylolisthesis
Repetitive spinal stress, such as gymnastics or football, increases risk. Other factors include spinal arthritis, genetic predisposition, and the natural aging process of the facet joints.
Stabilization Without Surgery for Spondylolisthesis
Many cases respond well to strengthening the muscles that support the spine.
- Core-focused rehabilitation
- Anti-inflammatory medications
- Image-guided injections for nerve relief
- Activity modification and bracing
- Hamstring stretching programs
Surgical Stabilization for Spondylolisthesis
If slippage progresses or symptoms are severe, minimally invasive spinal fusion may be recommended to stabilize the spine and relieve nerve pressure.

Frequently Asked Questions
Is walking good for spondylolisthesis?
Yes, walking is beneficial. It strengthens the core and legs without placing heavy stress on the spine. However, avoid hyperextending (arching) the back, which can worsen the slip.
What grade of spondylolisthesis requires surgery?
Surgery is typically required for Grade 3 or 4 slips (over 50% slippage) or if lower grades cause intractable nerve pain. Spinal fusion stabilizes the slipped vertebra.
Can a chiropractor fix spondylolisthesis?
Chiropractors can provide symptom relief for mild slips, but they cannot push the vertebra back into place. High-velocity adjustments should be avoided in unstable, high-grade slips.
What exercises should be avoided with spondylolisthesis?
Avoid exercises that involve extension (arching the back), such as 'Superman' poses or heavy overhead lifting, as these can push the slipped vertebra further forward.
