Injection under Ultrasound Guidance
What is Injection Under Ultrasound Guidance?
The most common injection is that of steroid (cortisone) which is a very powerful anti-inflammatory medicine.
We would use this to break the cycle of pain and inflammation that we often see in the foot as it is very difficult to rest an injured area completely.
Using ultrasound guidance enables us to ensure that we are treating the exact structure which is affected.
Why do I need to have an Injection Under Ultrasound Guidance?
There are certain problems which respond very well to this
- Painful joints, such as hallux rigidus or metatarsalgia secondary to hallux valgus
- Plantar fasciitis
- Painful nerve conditions, such as Morton’s neuroma
- Painful bursitis, often associated with other deformities
- Painful trigger points such as nerve pain following an ankle sprain
- Painful tendonitis
How do you give an Injection Under Ultrasound Guidance?
If we are injecting the heel, we will always give you a local anaesthetic first. This is not necessary for all problems. We will do this in our clinic, under sterile conditions.
Frequently Asked Questions about Ultrasound-Guided Injections
What is an injection under ultrasound guidance?
It’s a precise treatment method where a steroid (or other medication) is injected directly into the affected area using real-time ultrasound to guide the needle and ensure accuracy.
What does the injection contain?
Typically, we use corticosteroids (steroids) – powerful anti-inflammatory medications – sometimes combined with a local anaesthetic for pain relief.
Why is ultrasound used?
Ultrasound allows us to see exactly where the inflamed or painful tissue is. This ensures the injection is delivered precisely, improving effectiveness and reducing risk.
What conditions can be treated this way?
We use ultrasound-guided injections to treat plantar fasciitis, Morton’s neuroma, bursitis, tendonitis, hallux rigidus, metatarsalgia, and other painful soft tissue or joint conditions.
Does the injection hurt?
If we’re treating the heel, we’ll usually give a local anaesthetic first. Discomfort is typically minimal and the procedure is performed under sterile clinical conditions.
How soon will I feel relief?
Some patients feel relief within days, while for others it may take 1–2 weeks. The steroid works gradually to reduce inflammation.
Are there any risks or side effects?
As with any injection, there’s a small risk of temporary discomfort, bruising, or infection. Your podiatrist will discuss all considerations with you beforehand.
