Spondylolisthesis

 

Introduction

Spondylolisthesis is a spinal condition that occurs when one of the vertebrae in the spine slips forward over the one below it. This displacement can potentially lead to nerve compression, discomfort, and functional limitations. While the condition can vary widely in its severity and impact, early recognition and a tailored approach to management may help improve overall quality of life.

At Joint Injections, our clinicians utilise ultrasound-guided caudal epidural steroid injections and nerve block injections as part of a broader strategy to manage symptoms in appropriate cases of spondylolisthesis. This blog aims to provide an overview of the condition, its underlying anatomy and causes, clinical presentation, diagnostic methods, and commonly employed non-surgical management techniques.

Spinal Anatomy in Focus

The human spine consists of 33 vertebrae, segmented into five regions: cervical, thoracic, lumbar, sacral, and coccygeal. Each vertebra is separated by intervertebral discs and interconnected by facet joints and ligaments that help maintain structural integrity and facilitate movement.

In spondylolisthesis, the misalignment typically affects the lumbar spine, particularly at the L4-L5 or L5-S1 levels. When the vertebra slips forward, the spinal canal may narrow, possibly affecting nearby nerves. This can lead to symptoms that extend into the lower back, hips, or legs.

Types of Spondylolisthesis

Spondylolisthesis is categorised into several types based on the underlying cause:

  • Congenital: Present at birth due to abnormal vertebral formation.
  • Isthmic: Caused by a defect or fracture in a part of the vertebra called the pars interarticularis.
  • Degenerative: Common in older adults, resulting from age-related wear of the spinal discs and joints.
  • Traumatic: Arising from direct trauma or injury.
  • Pathological: Associated with disease processes such as tumours or infections.
  • Post-surgical: Following spinal procedures.

Among these, degenerative spondylolisthesis is particularly prevalent and often linked with other spinal changes such as facet joint osteoarthritis and disc degeneration.

Risk Factors

Certain factors may increase the likelihood of developing spondylolisthesis, including:

  • Ageing, particularly over 50
  • Repetitive spinal strain or trauma
  • High-impact sports
  • Congenital spinal anomalies
  • Previous spinal surgery
  • Family history of spinal disorders

Symptoms

The severity and type of symptoms can vary significantly depending on the extent of vertebral slippage and whether nerves are affected. Commonly reported symptoms include:

  • Localised lower back pain
  • Stiffness or reduced range of motion
  • Radiating pain to the buttocks or legs (sciatica-like symptoms)
  • Tingling or numbness in the lower limbs
  • Muscle weakness
  • In rare cases, changes in bladder or bowel habits

Not every person with spondylolisthesis experiences noticeable symptoms. In fact, some cases are discovered incidentally during imaging for unrelated issues.

Diagnosis

A detailed clinical history and physical examination by a clinician often guide the diagnostic process. Imaging studies may be utilised to confirm the diagnosis and assess the degree of vertebral slippage.

Non-Surgical Management

The goal of non-surgical management is to address discomfort and functional limitations while improving spine stability and flexibility. Treatment strategies may vary based on the individual’s symptoms, age, and activity level.

Activity Modification

Temporary adjustments to daily activities can help avoid aggravating movements and provide the spine with time to stabilise.

Ultrasound-Guided Interventions at Joint Injections

In individuals where symptoms persist despite initial conservative measures, image-guided injections may play a role in managing inflammation or nerve irritation.

Caudal Epidural Steroid Injection

At Joint Injections, our clinicians use ultrasound guidance to deliver corticosteroid medication into the caudal epidural space — the lowest part of the spinal canal. This approach helps with precise delivery while avoiding the need for fluoroscopy or ionising radiation.

This type of injection is considered in selected individuals with lower back pain and/or radiating leg symptoms associated with spondylolisthesis.

Nerve Block Injections

Ultrasound-guided nerve block injections may be used to target specific nerves that are potentially irritated or compressed by the slipped vertebra. These injections are generally used in specific diagnostic or therapeutic contexts and are tailored to the individual’s presentation.

All procedures are carried out by experienced clinicians in controlled environments with appropriate monitoring.

Tailored Management at Joint Injections

At Joint Injections, we aim to provide individualised care that incorporates:

  • Detailed clinical assessment
  • Ultrasound-guided injections to enhance accuracy and reduce risks
  • A collaborative approach with other clinician including physiotherapists and spinal specialists when necessary

By tailoring care to the specific presentation and needs of each person, we strive to support improved daily function and long-term spinal health.

Final Thoughts

Spondylolisthesis can present with a range of symptoms from mild discomfort to more persistent nerve-related issues. A structured, stepwise approach to evaluation and management often provides the best outcomes. At Joint Injections, our use of ultrasound-guided caudal epidural steroid injections and nerve block injections allows for precise, image-guided care where appropriate.

If you’re dealing with lower back pain or symptoms suggestive of spondylolisthesis, a thorough assessment may help guide your next steps. Our team is here to support you through evidence-informed strategies tailored to your needs.

Ultrasound-Guided Cortisone Injections for Baxter’s Nerve Entrapment

Image
  Introduction Baxter’s Nerve Entrapment , also known as inferior calcaneal nerve entrapment, is a condition that can contribute to chronic heel pain. It is often misdiagnosed as plantar fasciitis due to the overlap in symptoms. The condition arises when the first branch of the lateral plantar nerve, known as Baxter’s nerve, becomes compressed or irritated. Anatomy of Baxter’s Nerve Baxter’s nerve is a branch of the lateral plantar nerve, which originates from the tibial nerve. This small but significant nerve travels along the medial aspect of the heel and innervates the abductor digiti minimi muscle of the foot. Due to its anatomical course, Baxter’s nerve is prone to compression between the deep fascia of the abductor hallucis muscle and the medial calcaneal tuberosity. Pathology and Causes of Entrapment Baxter’s nerve entrapment  occurs when the nerve is compressed or irritated due to various factors, including: Repetitive stress and overuse  — Activities such as prol...
