Spondylolisthesis occurs when one vertebra slips forward relative to the one below it. This can cause low back pain, instability, and, in some cases, nerve compression leading to leg symptoms.
Quick Facts:
- Common cause of low back pain
- Often mild and stable
- May cause nerve compression (leg pain)
- Many cases are treated without surgery
👉 Request an Appointment
👉 Refer a Patient
WHAT IS SPONDYLOLISTHESIS?
The spine is made up of stacked bones (vertebrae) that normally align in a stable column.
Spondylolisthesis occurs when:
- One vertebra shifts forward relative to another
- This can change alignment and stability
- It may narrow the space for nearby nerves
There are different types, including:
- Degenerative (most common, related to aging)
- Isthmic (related to a defect in the bone)
- Traumatic or other less common causes
👉 The key issue is whether the slip is stable and asymptomatic or causing symptoms
IS THIS SERIOUS?
In many patients, spondylolisthesis is not serious.
Typical Cases
- Mild slip
- Stable over time
- Causes back pain but no major nerve symptoms
More Significant Cases
- Progressive slip
- Nerve compression
- Leg pain or weakness
👉 The severity depends on degree of slip and whether nerves are affected
SYMPTOMS
Common Symptoms
- Low back pain
- Stiffness
- Pain with standing or walking
When Nerves Are Affected
- Pain radiating into the legs
- Numbness or tingling
- Weakness
Typical Pattern
- Pain often worsens with standing or walking
- Pain may improve with sitting or bending forward
🚨 When to Seek Prompt Evaluation
- Progressive weakness
- Difficulty walking
- Persistent or worsening leg pain
- Symptoms affecting daily function
👉 These may indicate nerve compression
CAUSES & RISK FACTORS
Common Causes
Degenerative (Most Common)
- Age-related changes in joints and discs
- Gradual loss of stability
Isthmic
- Small defect in part of the vertebra
- Often develops earlier in life
Other Causes
- Trauma
- Congenital conditions
Risk Factors
- Aging
- Repetitive stress
- Genetics
- Prior spine degeneration
HOW IS THIS DIAGNOSED?
A. Clinical Evaluation
Diagnosis begins with:
- Symptom history
- Physical exam
- Assessment of nerve function
B. Imaging
Imaging is essential for diagnosis.
- X-rays to assess alignment and degree of slip
- Flexion/extension X-rays to evaluate stability
- MRI to assess nerves and discs
- CT scan in select cases
👉 Imaging helps determine whether the slip is stable and whether nerves are affected
TREATMENT OPTIONS
A. Non-Surgical Treatment
Many patients improve without surgery.
Common treatments include:
- Physical therapy
- Core strengthening
- Activity modification
- Anti-inflammatory medications
- Injections in select cases
👉 The goal is to improve stability and reduce symptoms
B. When Is Surgery Considered?
Surgery may be considered when:
- Symptoms persist despite conservative care
- There is significant nerve compression
- There is instability
- Pain significantly affects quality of life
C. Surgical Options
When surgery is needed, options may include:
Decompression
- Relieves pressure on nerves
Fusion
- Stabilizes the spine
- Prevents further slipping
👉 The goal is to relieve nerve symptoms and restore stability
OUR APPROACH
We focus on understanding whether the slip actually matters clinically.
- Many patients have mild spondylolisthesis that does not require surgery
- The key is correlating symptoms with imaging
- We emphasize conservative treatment first when appropriate
- Surgery is recommended when there is clear benefit
👉 The goal is to treat symptoms and function—not just the presence of a slip
WHAT TO EXPECT
Before Treatment
- Evaluation of symptoms and imaging
- Determination of stability and nerve involvement
During Non-Surgical Care
- Focus on strengthening and symptom control
- Many patients improve over time
If Surgery Is Needed
- Procedure depends on nerve compression and stability
- Recovery varies based on the extent of surgery
OUTCOMES & RISKS
Outcomes
- Many patients improve with conservative care
- Surgical outcomes are generally good when:
- Nerve compression is addressed
- Instability is stabilized
Risks of Untreated Severe Cases
- Persistent pain
- Progressive nerve compression
- Weakness
- Reduced mobility
FREQUENTLY ASKED QUESTIONS
Does a “slip” mean my spine is unstable?
Not always. Many slips are stable and do not progress.
Will this get worse over time?
Not necessarily. Many cases remain stable.
Do I need surgery?
Most patients do not need surgery.
Why does it cause leg pain?
Because it can narrow the space for nerves.
