Performing an injection under ultrasound means the needle can be watched all the way to the target. Accuracy matters, but so does the decision about what to inject and whether to inject at all — and for joints and tendons we use corticosteroid sparingly.

What it can help with

  • A painful joint where a flare is preventing sleep or rehabilitation
  • An inflamed bursa, such as the subacromial or trochanteric bursa
  • Tendon sheath problems such as de Quervain's or trigger finger
  • Diagnostic injections, where the response helps localise the pain source
  • Nerve-related targets, including hydrodissection and perineural treatment

Suitability depends on your individual diagnosis and is assessed at consultation.

Performing an injection under ultrasound means the target is identified, the needle is watched all the way in, and the injectate is seen arriving in the right space. For small joints, bursae, tendon sheaths and anything near a nerve, that accuracy makes a real difference to both effectiveness and safety.

Ultrasound guidance sits at stage two of our treatment pathway, where the aim is to settle pain enough to let you rehabilitate. Some guided injections belong further along the pathway — platelet-rich plasma, prolotherapy, perineural therapy and nerve hydrodissection each have their own page.

Why we use corticosteroid sparingly

Cortisone works, in the short term, and that is exactly what makes it tempting. Beyond that window the evidence is less comfortable. In tendinopathy, trials that followed people out to a year found the early advantage of injection reversed, with worse outcomes than exercise alone. In joints, repeated injections have been associated with cartilage loss. And in every case, cortisone reduces pain without repairing anything.

So corticosteroid is not a stage of our pathway. It is an occasional tool, used for a defined reason — pain severe enough to block rehabilitation, a clear inflammatory or bursal target, a specific short-term goal, or a diagnostic question — and always alongside the loading work that changes the longer-term course.

Viscosupplementation

Hyaluronic acid injection into an arthritic joint is widely offered and genuinely contested. Some guideline bodies conclude the average benefit over a placebo injection is small and recommend against routine use; others allow it as an option in selected patients. Part of the difficulty is that injection itself often helps in trials, which makes the specific effect of the hyaluronic acid hard to isolate.

Where the evidence is mixed, we say so. Viscosupplementation may be discussed where corticosteroid is unsuitable or has been used repeatedly, and where you would like to try a non-steroid injection option before considering a surgical opinion.

How it works

Blind injections miss more often than most people expect, particularly around small joints, tendon sheaths and bursae. Ultrasound allows the target to be identified, the needle tracked in real time, and the injectate seen entering the right space. That improves accuracy and reduces the chance of injecting into a structure we did not intend to — a tendon, for example.

What is injected is a separate decision from how it is delivered. Local anaesthetic gives immediate, short-lived relief and is diagnostically useful. Corticosteroid reduces inflammation and pain for weeks to a few months. Dextrose, platelet-rich plasma and hyaluronic acid are covered on their own pages and sit at stage four of the pathway.

What the evidence shows

Guided corticosteroid injection has good short-term evidence in specific situations — an inflamed bursa, a tendon sheath, a single irritable joint, the painful phase of frozen shoulder, and around an entrapped nerve in carpal tunnel syndrome. Benefit is usually measured in weeks to a few months. The longer-term picture is where we differ from some clinics. In tendon problems, trials that followed people out to a year have found the early advantage of corticosteroid reversed, with worse outcomes than exercise alone, and there are reports of tendon rupture after injection into or close to a tendon. In joints, repeated corticosteroid injections have been associated with cartilage loss. Cortisone does not repair anything. We therefore do not build treatment plans around corticosteroid. It is used sparingly, for a defined reason, with the number kept low, and always paired with the loading work that changes the longer-term course.

What to expect

The area is scanned, the target confirmed and the skin cleaned. Local anaesthetic is used where appropriate. The injection itself usually takes a few minutes. You may feel pressure or a brief ache as the injectate goes in. Most people can drive and return to normal activity the same day; heavy loading of the treated area is usually held for a short period, and we will be specific about that. Some injections settle pain within days, others take a week or two.

Frequently asked questions

Why does ultrasound guidance matter?
Because it lets us see the needle reach the intended target and see the injectate arrive there. Blind injections miss more often than most people expect, particularly around small joints, tendon sheaths and bursae — and accuracy affects both how well an injection works and how safe it is.
Do you use cortisone?
Sometimes, and sparingly. It reliably reduces pain in the short term, which is genuinely useful when pain is blocking rehabilitation. But in tendon problems the early advantage can reverse by a year, and repeated joint injections have been associated with cartilage loss. Where an injection is the right call we explain what is being injected and why, keep the number low, and pair it with a loading programme.
What is viscosupplementation?
A gel-like hyaluronic acid injection into an arthritic joint. Guideline bodies genuinely disagree about it — some conclude the average benefit over a placebo injection is small and advise against routine use, others allow it in selected patients. We may discuss it where corticosteroid is unsuitable or has already been used repeatedly, with that disagreement stated openly.
How many injections can I have?
There is no single number, but fewer is better. If pain keeps returning after injections, the more useful question is usually what the plan is missing rather than when the next injection is due.
Is it covered by Medicare?
Guided injections are performed during a standard GP consultation and billed under the time-based GP consultation items, which attract a Medicare rebate. Consumables and some injectables are charged separately. Appointments are not bulk billed, so an out-of-pocket gap applies, and we confirm fees with you beforehand.
