Ultrasound-Guided Cortisone Injections for Lower Back Pain

 

Introduction

Lower back pain is one of the most common reasons people seek medical advice. It can affect anyone, regardless of age or activity level, and ranges from mild discomfort to persistent pain that interferes with daily life. The lower back, or lumbar region, supports much of the body’s weight and is essential for movement. Because of this, it is especially prone to strain, injury, and wear.

At Alton Pain Clinic, clinicians provide ultrasound-guided cortisone injections as one option for managing lower back pain. Using advanced imaging, these injections are delivered with accuracy and precision. This blog explores the anatomy of the lower back, common causes of pain, diagnosis, management strategies, and the role of ultrasound-guided cortisone injections.

Anatomy of the Lower Back

The lumbar spine is a complex structure of bones, muscles, discs, joints, ligaments, and nerves.

  • Lumbar vertebrae — Five large bones (L1–L5) that carry much of the body’s weight.
  • Intervertebral discs — Cushions between vertebrae that absorb shock and allow flexibility.
  • Facet joints — Small joints at the back of the spine that guide movement.
  • Muscles and ligaments — Provide strength, stability, and movement.
  • Nerves — Exit the spinal cord and travel to the legs, carrying signals for movement and sensation.

Causes of Lower Back Pain

There are many possible reasons for lower back pain, including:

  • Muscle strain or ligament sprain.
  • Age-related disc degeneration.
  • Herniated discs pressing on nerves.
  • Facet joint irritation.
  • Spinal stenosis (narrowing of the spinal canal).
  • Sacroiliac joint dysfunction.
  • Vertebral slippage (spondylolisthesis).
  • Fractures or trauma.

Symptoms

Lower back pain can vary in type and intensity. Common symptoms include:

  • Aching or sharp pain in the lumbar area.
  • Stiffness, especially after sitting or resting.
  • Pain radiating into the hips, buttocks, or legs.
  • Tingling, numbness, or weakness if nerves are affected.
  • Pain made worse by bending, twisting, or lifting.

Diagnosis

Clinicians use a combination of methods to identify the cause of pain:

  • Detailed history and physical examination.
  • Ultrasound to guide injections.

Management of Lower Back Pain

Treatment depends on the cause and severity of symptoms. Options may include:

  • Activity modification and lifestyle changes.
  • Manual therapy.
  • Injections such as ultrasound-guided cortisone.

Ultrasound-Guided Cortisone Injections

For ongoing lower back pain, cortisone injections guided by ultrasound may be used. These injections target specific areas, including:

  • Facet joints.
  • Sacroiliac joints.
  • Soft tissues around the lumbar spine.

Why ultrasound guidance?

  • Real-time imaging ensures accuracy.
  • Safer placement of the injection.
  • Delivery of cortisone exactly where it is needed.

Cortisone and Its Mechanism of Action

Cortisone is a corticosteroid medicine that reduces inflammation. Its main actions are:

  • Suppressing inflammatory chemicals in tissues.
  • Reducing swelling and irritation.
  • Calming irritated nerves.
  • Helping restore movement and function.

At Alton Pain Clinic, clinicians use ultrasound guidance to place cortisone with precision in the affected area.

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...

Tennis Elbow

  Introduction Tennis elbow , medically known as  lateral epicondylitis , is a condition that affects many individuals, not just athletes. Despite its name, it often arises in people who have never played tennis. It occurs when the tendons in the elbow become irritated, typically due to overuse or repetitive strain. The condition can lead to pain and discomfort, often limiting the ability to carry out daily tasks. At  Alton Pain Clinic , our clinicians frequently see patients experiencing tennis elbow, and we aim to provide an in-depth understanding of the condition. This blog explores its causes, symptoms, anatomy, diagnosis, and various management approaches, including the use of  ultrasound-guided steroid injections  as one of the treatment options we provide. Anatomy of the Elbow To understand tennis elbow, it helps to first appreciate the elbow’s anatomy. The elbow joint connects the  humerus  (upper arm bone) with the  radius  and ...

Ultrasound-Guided Cortisone Injections for Achilles Tendinopathy

Image
  Achilles tendinopathy   is a common condition affecting the Achilles tendon, which connects the calf muscles to the heel bone. This condition is characterised by pain, stiffness, and reduced function in the tendon, often developing due to repetitive strain or overuse. While it is prevalent among athletes, particularly runners, it can also affect individuals who engage in activities that place excessive stress on the tendon. Management options for  Achilles tendinopathy  vary depending on the severity and chronicity of the condition. Among the available treatment modalities, ultrasound-guided cortisone injections have gained attention as a potential intervention for managing tendon-related pain and inflammation. This blog will provide a comprehensive overview of Achilles tendinopathy, including its anatomy, pathology, risk factors, symptoms, diagnosis, and various management approaches. It will also explore the role of ultrasound-guided cortisone injections in manag...
