Ultrasound-guided elbow injections

The elbow packs tendons, nerves, blood vessels and small joint recesses into a tight space. Injecting “blind,” by feel alone, means guessing at depth and direction. Ultrasound guidance removes the guesswork.

Using live imaging, we watch the needle in real time and steer it precisely into the tendon sheath, bursa or joint — avoiding nearby nerves and blood vessels, and placing the medication exactly where it's needed rather than close by. Research and clinical guidelines consistently show ultrasound-guided injections are more accurate than landmark-guided ones, which translates into better, more reliable outcomes.

Why it matters: a steroid or hyaluronic acid injection only works as well as its placement. Ultrasound guidance means every injection we give is confirmed, on screen, to be exactly where it needs to be.

​

What happens during an elbow injection?

1. Scan and plan. We scan the elbow to confirm the diagnosis, identify the exact target, and plan the safest approach.

2. Skin preparation. The skin is cleaned, and a local anaesthetic is often used, either mixed with the steroid or applied first to numb the area.

3. Guided injection. Watching the live ultrasound image, the needle is guided to the target and the medication is delivered. Most people feel a brief pressure or scratch rather than significant pain.

4. Done. A small dressing is applied and you can get dressed straight away. The whole visit, scan included, typically takes around 30-40 minutes.

Most people are comfortable to drive themselves home afterwards, though it's sensible to take it easy with the arm for the rest of the day and to arrange a lift if you'd feel more comfortable with one. Your clinician will give you specific aftercare advice for your injection before you leave.

​

How quickly will the injection work?

This depends on which injection you've had:

• Steroid: the local anaesthetic often gives some numbness for a few hours. It's common for the elbow to feel slightly more sore for a day or two as the steroid settles in, before the anti-inflammatory effect takes over — most people notice a clear improvement within 1 to 3 days, continuing to build over the following 2-3 weeks.

• Hyaluronic acid: relief tends to build more gradually, typically over 1 to 3 weeks, as the tissue responds, rather than arriving all at once.

Everyone responds a little differently, and ongoing exercises or physiotherapy alongside the injection usually improve both the speed and durability of your recovery.

​

How long will the effects last?

Steroid injections typically provide relief for several weeks to a few months — long enough to break a painful cycle and let you progress with rehabilitation. Hyaluronic acid injections often provide relief lasting several months or longer, and because it supports the tissue's own repair rather than only reducing inflammation, improvements can continue after the injection itself has been absorbed.

Results vary from person to person, and how long relief lasts also depends on what's causing your pain, how long you've had it, and whether you follow through with any exercise programme we recommend alongside the injection. We'll agree a follow-up plan with you so we can track your progress and adjust treatment if needed.

​

Are elbow injections safe?

Yes — when performed by a trained practitioner under ultrasound guidance, both steroid and hyaluronic acid elbow injections are routine, well-established procedures with a good safety record. As with any injection, there are some things to be aware of:

​

Steroid injections — things to be aware of

• Temporary increase in pain or swelling for up to 7–10 days

• Small risk of skin thinning or pale patches at the injection site, especially with repeated injections in the same spot

• Brief facial flushing in some people

• Temporary rise in blood sugar for people with diabetes

• Small risk of infection — we use a strict sterile technique to minimise this

• Usually limited to around 2–3 injections per site each year, to protect the tendon

• You will need relative rest after the injection for approximately 2 weeks

​

Hyaluronic acid injections — things to be aware of

• Mild soreness or swelling at the injection site for a day or two is common

• Because it's a substance naturally found in the body, significant reactions are rare

• No known tissue-thinning risk, so it can usually be repeated more freely than steroid if needed

• Very rarely, a mild allergic-type reaction

We'll talk through the risks and benefits specific to your situation before any injection, and ultrasound guidance throughout the procedure is itself a safety measure — helping us avoid nearby nerves and blood vessels and place the medication accurately the first time.
