Sciatica

 Sciatica is a condition that affects a significant portion of the population at some point in life. It is not a diagnosis in itself but rather a term used to describe a set of symptoms related to irritation or compression of the sciatic nerve. These symptoms can be distressing, impacting movement, quality of life, and daily function. At Joint Injections, we aim to provide comprehensive support and advanced options such as ultrasound-guided cortisone injections to assist in managing such discomfort under the direction of experienced clinicians.

Understanding the Sciatic Nerve

The sciatic nerve is the largest and longest nerve in the body. It originates in the lower back (lumbar spine), travels through the buttocks, and continues down each leg to the feet. The nerve is formed from the nerve roots emerging from the lower part of the spine (L4–S3) and plays a vital role in transmitting motor and sensory information to and from the legs.

Any disruption, irritation, or compression of this nerve can lead to the development of sciatica symptoms.

What is Sciatica?

Sciatica refers to pain that radiates along the path of the sciatic nerve. It is usually experienced on one side of the body, starting from the lower back or buttock and extending down the leg, sometimes reaching the toes. While the pain can vary in intensity and duration, it is commonly described as sharp, burning, or shooting.

Sciatica is often accompanied by other symptoms such as:

  • Numbness or tingling in the leg or foot
  • Weakness in the affected leg
  • Difficulty sitting, standing, or walking for extended periods
  • Pain that worsens with movement or coughing

Causes of Sciatica

Sciatica typically arises from an underlying structural issue. Common causes include:

1. Herniated Disc

A disc in the spine may bulge or rupture, pressing on nearby nerve roots.

2. Degenerative Disc Disease

With age, spinal discs may degenerate, reducing cushioning and allowing for nerve impingement.

3. Spinal Stenosis

Narrowing of the spinal canal can compress nerves, including the sciatic nerve roots.

4. Spondylolisthesis

A vertebra slipping forward over the one below it can pinch the nerve roots exiting the spine.

5. Piriformis Syndrome

In some cases, the piriformis muscle in the buttocks may irritate or compress the sciatic nerve.

Risk Factors

Certain factors may increase the likelihood of developing sciatica:

  • Sedentary lifestyle
  • Occupational strain (heavy lifting or prolonged sitting)
  • Poor posture
  • Age-related changes in the spine
  • Obesity
  • Previous lower back injury

Diagnosis

At Joint Injections, a clinician typically begins with a thorough clinical history and physical examination. Diagnostic imaging such as MRI or CT scans may be recommended to identify the specific cause of nerve compression.

Common assessment steps may include:

  • Evaluation of reflexes and muscle strength
  • Sensory tests (pinprick, vibration)
  • Straight-leg raise test
  • Observation of walking pattern and posture

Management of Sciatica

Management of sciatica often depends on its underlying cause and severity. Treatment is typically focused on symptom relief and functional recovery. Approaches may include:

1. Activity Modification

Avoiding aggravating activities and introducing gentle movement.

Role of Cortisone Injections

When sciatica does not respond adequately to conservative measures, targeted injections may be considered. At Joint Injections, we offer ultrasound-guided cortisone injections, which allow clinicians to deliver medication with precision to the affected area.

Cortisone, a type of corticosteroid, may assist in reducing inflammation around the irritated nerve root. When guided by ultrasound, the injection can be performed under real-time visualisation, helping to target the precise location and enhance procedural accuracy.

Benefits of Ultrasound Guidance:

  • Real-time visualisation of soft tissues and nerves
  • Reduced risk of damage to surrounding structures
  • Precise targeting of medication
  • No radiation exposure

The aim of this procedure is to support symptom relief and allow individuals to resume physical rehabilitation or daily activities with more ease.

When is Injection Considered?

Injections may be explored when:

  • Symptoms persist beyond several weeks
  • Pain affects mobility or daily function
  • There is difficulty engaging in physiotherapy due to discomfort
  • Oral medications have limited effect

A clinician will assess the appropriateness of this approach based on clinical findings and imaging.

Recovery and Follow-Up

Following an injection, patients are usually monitored for a brief period before resuming activities. Some experience temporary numbness or mild soreness at the injection site. A personalised care plan may be discussed to guide the next steps, which may include ongoing physiotherapy or further diagnostic evaluation if necessary.

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...
