Spondylolisthesis is a condition where one of the bones in your spine, known as a vertebra, slips forward over the bone below it. It can lead to back pain and other symptoms, affecting individuals’ quality of life.

What is Spondylolisthesis?

Spondylolisthesis is a spinal condition involving the displacement of one vertebra over another. This displacement can be a forward slip, known as anterolisthesis, or a backward slip, known as retrolisthesis. The severity of the slip is graded on a scale from I to V, depending on the extent of the vertebra’s movement.

5 Types of Spondylolisthesis

There are several types of spondylolisthesis, each with unique characteristics:

1. Isthmic Spondylolisthesis

This type occurs due to a defect in the bone that connects the upper and lower facets of a vertebra. It is commonly seen in adolescents and young adults.

2. Degenerative Spondylolisthesis

Common in older adults, this type results from aging and the general wear and tear on the spine that occurs over time.

3. Congenital Spondylolisthesis

Present at birth, this form is caused by abnormal bone formation, putting the vertebrae at risk for slipping.

4. Traumatic Spondylolisthesis

This type is due to direct trauma or injury to the vertebrae.

5. Pathological Spondylolisthesis

Caused by a condition such as a tumor or disease that weakens the bones.

Causes and Risk Factors of Spondylolisthesis

While the exact cause of spondylolisthesis varies depending on the type, several factors can increase the risk of developing the condition:


  1. Genetics: A family history of spondylolisthesis can increase risk.
  2. Age: Degenerative changes in the spine are more common in older adults.
  3. Physical Activities: Athletes, particularly those in sports that put stress on the back, are at higher risk.
  4. Trauma: Accidents or injuries can lead to vertebral displacement.
  5. Other Spinal Conditions: Conditions like osteoporosis and arthritis can contribute to the development of spondylolisthesis.

Symptoms of Spondylolisthesis

The symptoms of spondylolisthesis vary depending on the severity and type of the slip. Common symptoms include:


  1. Lower Back Pain: Often the most common symptom, especially during activity.
  2. Stiffness and Tightness: In the back and hamstrings.
  3. Pain Radiating Down the Legs: Due to nerve compression.
  4. Postural Changes: Including swayback (lordosis) and rounding of the upper back (kyphosis).
  5. Numbness, Weakness, or Tingling: In the legs or feet.
  6. Restricted Mobility: Difficulty in walking or standing for long periods.

Diagnosis of Spondylolisthesis

Diagnosing spondylolisthesis involves a comprehensive approach:


Medical History and Physical Examination: To assess symptoms and identify any risk factors.

Imaging Tests: X-rays are the primary tool, but MRI or CT scans may be used for a more detailed view.

Grading System of Spondylolisthesis

The severity of spondylolisthesis is typically graded on a scale from I to V:


Grade I: Less than 25% slip.

Grade II: 25% to 50% slip.

Grade III: 50% to 75% slip.

Grade IV: 75% to 100% slip.

Grade V: Complete slip (spondyloptosis).

Complications of Spondylolisthesis

If left untreated, spondylolisthesis can lead to:


Chronic Pain: Persistent back pain.

Permanent Nerve Damage: Leading to weakness, numbness, or even paralysis.

Increased Mobility Issues: Difficulty in walking or performing daily activities.

Postural Changes: Significant changes in spine alignment.

Managing Symptoms of Spondylolisthesis

While treatment options are not discussed here, managing the symptoms of spondylolisthesis is crucial. This can include lifestyle modifications, physical therapy, and techniques to manage pain and improve spinal stability.


Can spondylolisthesis affect children and adolescents?

Yes, spondylolisthesis can affect children and adolescents, particularly those engaged in activities that stress the lower back, such as gymnastics or weightlifting. Early detection is key to managing the condition effectively in younger patients.

Yes, spondylolisthesis involves the slippage of a vertebra, while a herniated disc refers to a problem with the cushioning discs between the vertebrae. Both conditions can cause back pain but have different underlying issues.

Absolutely, lifestyle changes such as maintaining a healthy weight, engaging in low-impact exercises, and practicing good posture can help in managing the symptoms of spondylolisthesis and improve spinal health.

The progression of spondylolisthesis varies; it can remain stable for years or progressively worsen. Regular monitoring and lifestyle modifications can play a significant role in managing its progression.

The progression of spondylolisthesis varies; it can remain stable for years or progressively worsen. Regular monitoring and lifestyle modifications can play a significant role in managing its progression.

Spondylolisthesis can lead to changes in spinal alignment and mobility, potentially contributing to other conditions such as spinal stenosis or increased curvature of the spine (kyphosis or lordosis).


Spondylolisthesis is a complex condition that requires careful attention and management. Understanding its types, causes, and symptoms is crucial for effective symptom management and maintaining a healthy, active lifestyle.
