Spondylolisthesis
What is Spondylolisthesis?
Spondylolisthesis is a spinal condition characterised by the displacement of one vertebra over another, usually in the lower back. This misalignment can lead to nerve compression and instability in the spine, resulting in various symptoms and complications. Spondylolisthesis is often graded based on the degree of slippage, with mild cases showing minimal displacement and severe cases indicating significant misalignment.
Symptoms
The symptoms of spondylolisthesis can vary widely, depending on the severity of the condition and the extent of nerve involvement. Common symptoms include:
- Lower back pain
- Sciatica, characterised by pain radiating down the legs
- Muscle weakness in the legs
- Numbness or tingling in the lower extremities
- Stiffness in the back
- Difficulty walking or standing for prolonged periods

Treatments We Offer:
At Alton Pain Clinic, two common treatments offered for spinal stenosis are Caudal Epidural Injections and Nerve Block Injections. These non-surgical options aim to relieve pain and improve mobility by reducing inflammation or blocking pain signals.
- Caudal Epidural Injection:
A Caudal Epidural Injection delivers anti-inflammatory medication, usually a corticosteroid, into the epidural space located at the base of the spine (the caudal area). This treatment helps reduce inflammation and swelling of the nerves, providing relief from pain. - Nerve Block Injection:
A nerve block injection targets specific nerves that are causing pain. By injecting an anaesthetic and a steroid around these nerves, the injection interrupts pain signals travelling from the spine to the brain, providing pain relief and reducing inflammation.
Pain relief mechanism of Epidural Steroid Injection
- Reduces Nerve Inflammation
The corticosteroids in the injection decrease inflammation in the epidural space, alleviating pressure on nerve roots affected by spondylolisthesis. - Interrupts Pain Signal Transmission
The injection blocks the transmission of pain signals from the affected spinal segment to the brain, providing immediate relief. - Decreases Swelling in the Epidural Space
The anti-inflammatory properties of the steroids reduce swelling around displaced vertebrae, easing compression on nearby nerves. - Relaxes Spinal Nerve Irritation
By addressing irritation and inflammation, the injection soothes the nerves impacted by the vertebral misalignment. - Inhibits Pain Pathways
Local anaesthetics, often included in the injection, block nerve conduction, temporarily numbing the affected area and reducing pain perception.
Benefits of Epidural Steroid Injection
- Effective Pain Relief
Provides targeted relief from lower back and leg pain associated with spondylolisthesis by addressing inflammation and nerve compression. - Minimally Invasive Procedure
Avoids the risks and recovery time associated with surgical interventions, making it a safer option for many patients. - Quick Onset of Relief
Delivers rapid pain reduction, enabling patients to return to daily activities sooner. - Reduces Inflammation
Corticosteroids work to decrease swelling and inflammation in the epidural space, relieving pressure on nerve roots. - Improves Mobility
Alleviates pain and stiffness, allowing for better participation in physiotherapy or exercise programmes aimed at strengthening the spine.
Pain relief mechanism of Nerve Block Injections
- Interrupts Pain Signal Transmission
The injection blocks the transmission of pain signals from the affected spinal nerves to the brain, providing immediate relief. - Reduces Nerve Irritation
The local anaesthetic component soothes irritated nerve roots compressed or impinged by vertebral slippage. - Decreases Inflammation
The corticosteroids in the injection reduce inflammation and swelling in the surrounding tissues, alleviating pressure on the nerves. - Relaxes Surrounding Muscles
By blocking nerve signals, the injection helps relieve associated muscle tension and spasms, which often contribute to pain. - Targets Pain at the Source
Administered precisely to the affected area, the injection provides focused pain relief at the site of nerve compression.
Benefits of Nerve Block Injection
- Effective Pain Management
Provides targeted relief from pain caused by nerve compression and inflammation associated with spondylolisthesis. - Minimally Invasive
Avoids the risks, scarring, and recovery time associated with surgical interventions, making it a safer option for many patients. - Quick Relief
Often delivers immediate or rapid pain reduction, allowing patients to resume daily activities sooner. - Reduces Inflammation
Corticosteroids in the injection alleviate inflammation around the nerve roots, relieving pressure and discomfort.

Understanding Spondylolisthesis
Ultrasound Guided Procedure
Both treatments are performed under ultrasound guidance to ensure precise placement of the injections. This technique enhances safety and effectiveness, allowing the clinician to accurately target the affected area.
Anatomy
Understanding the anatomy involved in spondylolisthesis is crucial. The lumbar spine consists of five vertebrae, supported by intervertebral discs, ligaments, and muscles. When a vertebra slips out of alignment, it can place pressure on adjacent nerves, leading to pain and other symptoms.
Diagnosis
Diagnosis of spondylolisthesis typically involves a comprehensive clinical assessment, including a physical examination and imaging studies such as X-rays or MRI scans. These methods help determine the degree of slippage and assess any associated complications.
Causes
Several factors can contribute to the development of spondylolisthesis, including:
- Congenital defects in the spine
- Degenerative changes due to age
- Trauma or injury to the spine
- Repetitive stress or strain, particularly in athletes
- Certain medical conditions, such as osteoporosis
Other Treatment Options
In addition to caudal epidural and nerve block injections, other treatment options for spondylolisthesis may include:
- Physical therapy
- Pain management medications
- Bracing
- Surgery, in severe cases
Benefits of Caudal Epidural Injection
Caudal epidural injections provide several benefits, including:
- Targeted delivery of anti-inflammatory medication directly to the affected area
- Reduction of inflammation and pain in the lower back
- Improvement in mobility and function
- Minimally invasive procedure with a low risk of complications
Benefits of Nerve Block Injection
Nerve block injections also offer distinct advantages:
- Immediate pain relief by interrupting pain signals to the brain
- Diagnostic benefit by identifying the specific source of pain
- Potentially longer-lasting relief compared to traditional pain medications
When to Consider This Treatment
Consider caudal epidural or nerve block injections if:
- Conservative treatments have not provided adequate relief
- Pain significantly interferes with daily activities
- You experience symptoms that suggest nerve compression
By addressing the underlying pain mechanisms associated with spondylolisthesis, these treatments can enhance quality of life and facilitate a return to normal activities. If you are experiencing symptoms of spondylolisthesis, consult with a clinician at Alton Pain Clinic to explore your treatment options.
