What is Spondylolisthesis?
Spondylolisthesis is a condition where one vertebra slips forward over the vertebra below it. This slippage can compress nerves and cause pain, numbness, or weakness in the legs.
The condition most commonly affects the lower back (lumbar spine), particularly at the L4-L5 or L5-S1 levels. Spondylolisthesis is graded on a scale from Grade I (mild slippage) to Grade V (severe slippage).
There are several types of spondylolisthesis, including degenerative (caused by age-related wear), isthmic (caused by a stress fracture), congenital (present at birth), traumatic (caused by injury), and pathologic (caused by bone disease).
Signs & Symptoms
Many people with mild spondylolisthesis have no symptoms. When symptoms occur, they may include:
- Lower back pain, often worse with activity
- Pain, numbness, or tingling radiating down one or both legs
- Weakness in the legs
- Tight hamstring muscles
- Changes in posture or gait
- Difficulty standing or walking for extended periods
How is Spondylolisthesis Diagnosed?
- Physical Examination: Assessment of pain, flexibility, and neurological function
- X-rays: Standing X-rays clearly show vertebral slippage and degree of displacement
- MRI: Shows nerve compression and disc condition
- CT Scan: Detailed bone imaging to assess fractures or defects
Treatment Options
Non-Surgical Treatment
For mild to moderate spondylolisthesis, conservative treatment is often effective:
- Physical Therapy: Core strengthening and flexibility exercises
- Anti-inflammatory Medications: To reduce pain and inflammation
- Bracing: Back braces for support and stability
- Epidural Injections: Steroid injections to reduce nerve inflammation
- Activity Modification: Avoiding activities that worsen symptoms
Surgical Treatment
Surgery may be recommended for progressive slippage, severe symptoms, or when conservative treatment fails:
- Spinal Fusion: Stabilizing the slipped vertebra to prevent further movement
- Decompression: Creating more space for compressed nerves
- Minimally Invasive Approach: Smaller incisions for faster recovery
Frequently Asked Questions
Can spondylolisthesis get worse over time?
Yes, spondylolisthesis can progress, though it often remains stable. Regular monitoring with X-rays helps Dr. Rastegar track any changes and adjust treatment as needed.
What activities should I avoid with spondylolisthesis?
High-impact activities, heavy lifting, and sports that hyperextend the back (like gymnastics or football) may worsen symptoms. Dr. Rastegar will provide specific activity guidelines based on your severity and symptoms.
Is surgery always necessary for spondylolisthesis?
No. Many people with spondylolisthesis manage successfully with conservative treatment. Surgery is typically reserved for cases with significant symptoms, progressive slippage, or nerve compression that doesn't respond to non-surgical care.
How long is recovery after spondylolisthesis surgery?
Recovery varies based on the procedure performed. With minimally invasive fusion, most patients can return to light activities within 6-8 weeks and full activities within 3-6 months. Dr. Rastegar provides a personalized recovery plan.
