Spinal Stenosis

 Understanding the Condition and Management Approaches

Introduction

Spinal stenosis refers to a narrowing within the spinal canal, which may contribute to pressure on the spinal cord or the nerves branching from it. This condition is commonly observed in the lower back (lumbar spine) or neck (cervical spine) and may develop gradually over time. While often associated with ageing, various anatomical and pathological changes may play a role in its progression.

At Alton Pain Clinic, we aim to support individuals experiencing symptoms possibly linked to spinal stenosis through structured, evidence-informed approaches. Our clinicians offer ultrasound-guided procedures, including Caudal Epidural Steroid Injections and Nerve Block Injections, tailored to individual patient profiles.

Anatomy of the Spine

The spine is a complex structure made up of:

  • Vertebrae — The individual bones forming the spinal column
  • Intervertebral discs — Cushion-like structures between vertebrae, supporting movement and absorbing shock
  • Spinal cord and nerves — The central nerve bundle and its branches extending throughout the body
  • Facet joints and ligaments — Components that stabilise and support flexibility in the spine

In spinal stenosis, one or more of these anatomical components may change in a way that narrows the spaces through which nerves pass.

Causes and Risk Factors

Several factors can contribute to the development of spinal stenosis:

  • Degenerative changes — Wear and tear affecting discs, joints, or ligaments
  • Herniated discs — Protrusion of disc material possibly pressing on nerves
  • Thickened ligaments — Ligaments may become less flexible or enlarged with age
  • Bone overgrowth (osteophytes) — Bony spurs that form as part of degenerative processes
  • Spinal injuries — Trauma may lead to inflammation or dislocation
  • Congenital conditions — Some individuals are born with narrower spinal canals

Spinal stenosis is commonly observed in adults over the age of 50, though younger individuals with congenital spinal narrowing or spinal injury may also develop symptoms.

Symptoms and Presentation

Symptoms may vary depending on the location and severity of the narrowing. Common features may include:

  • Pain in the back, neck, or radiating along arms or legs
  • Numbness or tingling in the limbs
  • Muscle weakness, especially in the lower extremities
  • Difficulty with walking or balance
  • Heaviness or fatigue in the legs, particularly after standing or walking for extended periods

In the lumbar spine, this presentation is often referred to as neurogenic claudication — a form of pain that is usually relieved by sitting or bending forward.

Management Approaches

Management of spinal stenosis may be multifaceted and tailored to the individual’s symptoms, lifestyle, and overall health status.

Conservative Measures

  • Activity modification — Adjustments to daily activities to reduce strain on the spine

These approaches may be considered in early or mild cases, or as part of a broader treatment plan.

Ultrasound-Guided Injections at Alton Pain Clinic

For individuals whose symptoms remain difficult to manage with conservative strategies, minimally invasive injection therapies may be considered. At Alton Pain Clinic, we offer ultrasound-guided Caudal Epidural Steroid Injections and Nerve Block Injections delivered by experienced clinicians.

Caudal Epidural Steroid Injections

A Caudal Epidural Steroid Injection involves introducing corticosteroid medication into the epidural space at the base of the spine via the sacral hiatus. This approach may support inflammation management and is typically combined with a local anaesthetic to assist with comfort.

Ultrasound guidance ensures precision in needle placement, potentially enhancing the safety and efficiency of the procedure.

Nerve Block Injections

Nerve block injections aim to interrupt pain signals transmitted through specific nerve roots. These injections may help clinicians identify the likely pain source while also offering temporary relief, particularly in targeted areas of discomfort.

The use of ultrasound guidance enables real-time imaging of anatomical structures, which supports accuracy in delivering the medication to the intended location.

Role of Imaging in Ultrasound-Guided Injections

Ultrasound imaging offers a radiation-free, real-time visualisation of the relevant anatomical features. Benefits include:

  • Avoidance of ionising radiation
  • Dynamic visual feedback during injection
  • Improved localisation of nerves, muscles, and blood vessels
  • Enhanced patient comfort and reduced procedure time

At Alton Pain Clinic, clinicians utilise advanced ultrasound equipment to help ensure procedures are as tailored and accurate as possible.

Individualised Care at Alton Pain Clinic

Each individual’s experience of spinal stenosis may vary, and so should their treatment plan. At Alton Pain Clinic, our approach is guided by:

  • Detailed assessment by experienced clinicians
  • Ultrasound-guided interventions for greater precision
  • Clear communication about all available options

We aim to provide structured care plans with ongoing review and adjustments based on individual progress.

Final Thoughts

Spinal stenosis is a common spinal condition, particularly in older adults, and may lead to a range of symptoms affecting daily life. A careful clinical approach, guided by imaging and tailored interventions, may help in managing symptoms and improving comfort.

At Alton Pain Clinic, our team is experienced in providing ultrasound-guided Caudal Epidural Steroid Injections and Nerve Block Injections, with a strong focus on individual needs and preferences. Through structured planning, imaging-guided precision, and collaborative care, we aim to support patients in navigating spinal conditions with clarity and care.

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...
