Ultrasound-Guided Cortisone Injections at Sonoworld Diagnostic Services

Precise Pain Relief for Musculoskeletal Conditions

At Sonoworld Diagnostic Services in London, we understand the debilitating impact that chronic pain and inflammation can have on your daily life. Our specialist Injection Clinic offers advanced, targeted treatments, including ultrasound-guided cortisone injections, to provide effective and precise pain relief for a wide range of musculoskeletal conditions. Utilising state-of-the-art ultrasound technology, our experienced clinicians ensure optimal accuracy and safety, helping you return to your normal activities sooner.

What is an Ultrasound-Guided Cortisone Injection?

A cortisone injection, often referred to as a steroid injection, involves delivering a powerful anti-inflammatory medication (corticosteroid) directly into a specific area of your body. This medication works to reduce inflammation and alleviate pain in joints, tendons, bursae, and other soft tissues.

The critical advantage of an ultrasound-guided injection lies in the use of real-time ultrasound imaging. Unlike traditional 'blind' injections, which rely solely on anatomical landmarks, ultrasound guidance allows our clinicians to visualise the needle's path as it enters your body. This ensures the medication is delivered with pinpoint accuracy to the intended target, maximising its effectiveness and minimising the risk of complications.

Benefits of Ultrasound Guidance

Choosing an ultrasound-guided injection offers several significant benefits:

• Pinpoint Accuracy: Real-time visualisation ensures the cortisone is delivered precisely to the inflamed area, leading to more effective pain relief [1]. Studies have shown that ultrasound-guided injections are more accurate than injections performed without imaging guidance [2].
• Enhanced Safety: By clearly seeing surrounding structures such as nerves, blood vessels, and tendons, our clinicians can safely navigate the needle, avoiding potential damage and reducing the risk of adverse events [3].
• Reduced Discomfort: Precise needle placement can lead to a less painful procedure compared to unguided injections, as fewer attempts are needed to reach the target [4].
• No Radiation Exposure: Unlike fluoroscopy (a type of X-ray imaging), ultrasound uses sound waves, meaning there is no exposure to ionising radiation [5].
• Improved Outcomes: The combination of accuracy and safety often translates to better and more prolonged pain relief, facilitating faster recovery and enabling patients to engage more effectively with rehabilitation programmes [6].

Conditions Treated

Ultrasound-guided cortisone injections are highly effective for treating inflammation and pain associated with various musculoskeletal conditions, including but not limited to:

• Osteoarthritis: Particularly in joints such as the knee, hip, and shoulder.
• Tendinitis/Tendinopathy: Conditions like rotator cuff tendinitis, Achilles tendinitis, patellar tendinitis, and tennis/golfer's elbow.
• Bursitis: Inflammation of bursae, commonly seen in the shoulder (subacromial bursitis), hip (trochanteric bursitis), and elbow (olecranon bursitis).
• Carpal Tunnel Syndrome: Reducing inflammation around the median nerve in the wrist.
• Trigger Finger/Thumb: Alleviating inflammation in the tendon sheath.
• Plantar Fasciitis: Targeting inflammation in the plantar fascia of the foot.

What to Expect During and After Your Procedure

Before the Injection

Upon arrival at Sonoworld, our specialist will discuss the procedure with you, answer any questions, and obtain your informed consent. You will be positioned comfortably, and the skin over the injection site will be cleaned with an antiseptic solution.

During the Injection

Using the ultrasound scanner, the clinician will identify the precise target area. A local anaesthetic will be administered to numb the skin and superficial tissues, ensuring your comfort. Once the area is numb, the fine needle, guided by real-time ultrasound imaging, will be advanced to the target. You may feel some pressure, but significant pain is uncommon. The cortisone medication, often mixed with a local anaesthetic, will then be injected. The entire process typically takes around 15-30 minutes.

After the Injection

• Immediate Post-Procedure: You may experience some temporary numbness from the local anaesthetic. It is advisable to avoid strenuous activity for the remainder of the day.
• Pain Relief Onset: The local anaesthetic often provides immediate, temporary pain relief. The corticosteroid medication typically takes 2-3 days to start working, with its full effects becoming apparent within 7-14 days [7]. It is not uncommon to experience a temporary increase in pain (a 'steroid flare') for 24-48 hours after the injection, which can be managed with over-the-counter pain relief and ice packs.
• Recovery: Your specialist will provide specific post-injection instructions tailored to your condition. Generally, you can resume light activities after 24-48 hours, gradually increasing activity as pain allows. Physical therapy may be recommended to maximise the benefits of the injection and aid long-term recovery.

Frequency of Injections

Cortisone injections provide a window of pain relief, which can last for several weeks to months. While highly effective, these injections are typically limited to 2-3 times per year in any single joint or area to minimise potential side effects, such as weakening of tendons or thinning of skin [8]. Your Sonoworld specialist will discuss the appropriate frequency and long-term management plan for your condition.

Is an Ultrasound-Guided Injection Right for You?

Our specialists at Sonoworld will conduct a thorough assessment to determine if an ultrasound-guided cortisone injection is the most appropriate treatment for your condition. While generally safe, there are some considerations:

• Diabetes: Corticosteroids can temporarily increase blood sugar levels. If you have diabetes, your blood sugar will need to be closely monitored [9].
• Infection: Injections are avoided if there is an active infection in or around the injection site.
• Allergies: Inform your clinician of any allergies, particularly to local anaesthetics or corticosteroids.
• Blood Thinners: If you are taking blood-thinning medication, this will need to be discussed with your specialist, as adjustments may be necessary.
