Degenerative Disc Disease

 

Introduction

Degenerative Disc Disease (DDD) is a term used to describe the natural wear and tear of the intervertebral discs in the spine. Despite the word “disease,” DDD is not actually a disease but rather a condition that can result in pain, restricted mobility, and functional limitations. It is often associated with ageing, though it may develop earlier in individuals who have experienced repetitive strain, spinal injuries, or genetic predispositions.

At Joint Injections, we offer structured, clinician-led care plans for managing spinal conditions, including ultrasound-guided Caudal Epidural Steroid Injections and Nerve Block Injections tailored to patient needs. This blog explores Degenerative Disc Disease in depth — its causes, symptoms, diagnostic process, and the role of targeted injection therapy.

Anatomy of the Spine

The human spine comprises 33 vertebrae divided into five main regions: cervical, thoracic, lumbar, sacral, and coccygeal. Between each vertebra lies an intervertebral disc made of a tough outer layer (annulus fibrosus) and a softer inner core (nucleus pulposus).

These discs serve several functions:

  • Acting as shock absorbers
  • Allowing flexibility and movement
  • Maintaining spacing between vertebrae to protect nerves

With age or due to other contributing factors, these discs can lose their structural integrity, resulting in Degenerative Disc Disease.

Causes and Contributing Factors

The primary cause of DDD is age-related disc degeneration, but other contributing factors include:

  • Genetics: A familial predisposition to disc wear
  • Repetitive motion: Occupational or lifestyle-related spinal stress
  • Spinal injuries: Trauma leading to disc weakening or early degeneration
  • Obesity: Increased spinal load causing disc strain
  • Smoking: Reduced disc oxygenation and impaired healing capacity

Pathophysiology

Degeneration begins when the intervertebral discs start to lose their water content, leading to a decrease in disc height. This reduces their cushioning ability and can result in:

  • Microtears in the annulus fibrosus
  • Disc bulging or herniation
  • Inflammation of nearby spinal nerves
  • Formation of bone spurs (osteophytes)

As these changes progress, pain and neurological symptoms may develop depending on the location and extent of degeneration.

Symptoms

Symptoms of DDD can vary depending on the affected spinal level. Commonly reported signs include:

  • Persistent back pain (especially in the lower back)
  • Neck discomfort
  • Radiating pain to the buttocks, thighs, or arms
  • Tingling, numbness, or weakness in the extremities
  • Stiffness or restricted mobility
  • Pain that worsens with bending, lifting, or twisting

In some cases, the degeneration may be asymptomatic and only identified during imaging for other concerns.

Diagnosis

A thorough clinical assessment is vital in diagnosing DDD. At Joint Injections, our clinicians perform detailed evaluations which may include:

  • Medical history review
  • Physical examination focusing on range of motion, reflexes, and neurological signs

These investigations help guide appropriate treatment plans tailored to individual needs.

Management Options

There is no universal treatment for Degenerative Disc Disease. Management usually depends on the severity of symptoms and may include:

1. Conservative Treatment

  • Activity modification and rest
  • Heat or cold therapy
  • Analgesics or anti-inflammatory medications

2. Injection-Based Interventions

At Joint Injections, we specialise in ultrasound-guided spinal injections designed to provide targeted care. These procedures are performed by experienced clinicians using real-time imaging for precision and safety.

Caudal Epidural Steroid Injection

A Caudal Epidural Steroid Injection involves administering a corticosteroid and local anaesthetic into the epidural space via the sacral hiatus. This technique is particularly suitable for lower lumbar disc degeneration and can support symptom relief by addressing inflammation around irritated nerve roots.

Benefits may include:

  • Reduction in nerve root irritation
  • Improved mobility

Nerve Block Injections

Nerve Block Injections involve the targeted delivery of medication near specific spinal nerves that may be contributing to pain. These injections are guided via ultrasound to ensure accurate placement.

They are commonly considered for:

  • Localising the source of pain
  • Managing neuropathic symptoms such as tingling or shooting pain

At Joint Injections, we prioritise patient comfort, accuracy, and procedural safety. All injections are performed under ultrasound guidance, allowing for real-time visualisation of anatomical structures.

Role of Ultrasound Guidance

Ultrasound technology enables clinicians to visualise soft tissue structures and needle placement dynamically. This helps:

  • Enhance procedural accuracy
  • Minimise risk to surrounding tissues
  • Reduce the volume of medication required
  • Improve patient experience

By using ultrasound guidance, the injections at Joint Injections are performed with a high degree of anatomical precision.

Living with Degenerative Disc Disease

Management of DDD often involves a multidisciplinary approach, combining medical treatment, guided injections, and self-care strategies. Individuals are encouraged to:

  • Maintain a healthy weight
  • Engage in regular low-impact exercise (e.g., walking, swimming)
  • Use proper lifting techniques
  • Avoid prolonged sitting or poor posture
  • Stop smoking, if applicable

Ongoing support and guidance from clinicians can help individuals adapt to changes and maintain an active lifestyle.

  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...
