Barbotage for calcific tendinopathy

An ultrasound-guided needle procedure that flushes and aspirates a calcium deposit in a tendon (most often in the shoulder rotator cuff). It may help selected patients, but sham-controlled evidence has questioned how much benefit comes from the lavage itself, so expectations should be cautious.

In short

  • Barbotage uses ultrasound-guided needles to flush out and break up a calcium deposit in a tendon, usually in the shoulder, often with a steroid injection alongside.
  • It can ease pain for some people, but evidence that it beats other treatments is limited, and calcium often partly remains even when symptoms improve.
  • It is usually considered for stubborn, painful calcific tendinopathy after simpler measures, alongside rehabilitation.
  • A flare of pain in the first day or two is common; be wary of clinics that promise a complete, guaranteed cure.

What is barbotage for calcific tendinopathy?

Calcific tendinopathy is a build-up of calcium within a tendon — most commonly in the rotator cuff of the shoulder — which can cause pain and stiffness. Barbotage is a procedure that uses one or two needles, guided by ultrasound, to inject and draw back (aspirate) saline so the calcium deposit is softened, fragmented and partly washed out. A steroid is often also injected into the nearby bursa to help with pain.

It is sometimes offered for calcific tendinopathy that is painful and has not settled with simpler measures such as rehabilitation, pain relief or, in some cases, shockwave therapy. It is a minor needle procedure, not surgery.

Barbotage can give useful pain relief for some people, but it is not a guaranteed cure. The evidence is limited: a systematic review concluded there is not enough good-quality evidence to say it is better than other treatments, partly because techniques vary. Residual calcium often remains on later scans even when pain improves, and some studies suggest similar results with simpler treatment.

This guide explains what to expect and how to judge whether it is being offered responsibly.

Types, options & approaches

There may be different ways to do this. The right approach depends on the clinical question and your circumstances.

Single-needle technique
One needle is used to inject and aspirate saline to soften and wash out the calcium. Simpler, but can be slower to clear a hard deposit.
Double-needle (two-needle) technique
Two needles are placed so fluid flows in through one and out through the other, which can help wash out softer deposits more efficiently.
Barbotage with subacromial steroid
A steroid is commonly injected into the nearby bursa at the same time to reduce pain and the chance of a post-procedure flare. Steroid has its own considerations to discuss.
Ultrasound guidance
The whole procedure is done under ultrasound so the needle(s) can be placed accurately into the calcium and nearby structures avoided. Guidance is central to the procedure.

Main downsideSlowDiscomfort, uncertainFlare, uncertain benefit

Calcific tendinopathy often settles in time. Barbotage is an option for stubborn, painful cases, not a guaranteed cure.

Preparing for your procedure

  • Tell the clinician your full medical history, including any bleeding problems, blood-thinning medicines, diabetes, infection or skin problems over the shoulder.
  • Discuss what you have already tried — rehabilitation, pain relief, and whether shockwave therapy has been considered.
  • Ask whether a steroid will be injected at the same time and discuss its risks and benefits.
  • Ask how the procedure is done (single or double needle), and what realistic pain relief to expect.
  • Plan for the shoulder to be sore for a few days and arrange to ease off using the arm heavily.
  • Consider arranging a lift home, as the shoulder may be uncomfortable afterwards.

What happens

Barbotage is done as an outpatient with you awake. The skin over the shoulder is cleaned and local anaesthetic is given. Using ultrasound to see the calcium deposit, the clinician advances one or two needles to it.

Saline is injected and drawn back repeatedly to soften, fragment and wash out the calcium, and some of it may be aspirated through the needle. A steroid is often injected into the nearby bursa to help with pain and reduce the chance of a flare.

The procedure usually takes around 20–40 minutes. There is no surgical wound, only needle puncture sites, which may be sore for a few days. You can normally go home soon afterwards. Your clinician will advise on pain relief, easing the arm, and returning to rehabilitation.

Is this procedure right for me?

A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.

May not be suitable if…

  • You have an active infection at or near the shoulder, or are generally unwell.
  • You have a significant bleeding disorder, or take blood thinners that cannot be safely managed.
  • Your shoulder pain is from a different cause that has not been properly diagnosed.
  • There is no clear calcium deposit to target on ultrasound.
  • Your symptoms are mild and likely to settle with simpler measures and time.

Delay or rearrange if…

  • You have an active infection anywhere, particularly over the shoulder.
  • You are pregnant or breastfeeding and this has not been discussed, especially if steroid is involved.
  • Your diagnosis is uncertain or has red-flag features that have not been assessed.
  • You have recently started a blood thinner or had a change in bleeding risk.
  • Your blood sugar is poorly controlled and a steroid injection is planned, until this is discussed.

Alternatives to discuss

  • Rehabilitation, pain relief and time, as many cases of calcific tendinopathy settle on their own.
  • Extracorporeal shockwave therapy, with its own mixed evidence.
  • A subacromial steroid injection alone for pain in selected cases.
  • Watchful waiting with monitoring.
  • Referral to a shoulder specialist or surgeon if symptoms persist or are severe.

Before you decide

Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.

What matters most to me?

Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.

What are all my options?

Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.

What would make me pause?

Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.

What happens if I do nothing today?

For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.

Comfort, sedation or contrast choices

If local anaesthetic, sedation, contrast or pain relief is used, ask what is planned, why, and what it means afterwards.

Local anaesthetic
Local anaesthetic is used to numb the skin and deeper tissues; you stay awake throughout.

Benefits

  • Done under ultrasound guidance, so the needle can be placed accurately into the calcium
  • Can reduce pain and improve shoulder function in many people
  • May speed up clearance of the calcium compared with leaving it alone, though calcium often partly remains
  • Avoids, or delays, the need for surgery in some people
  • Only a minor needle procedure, usually done as an outpatient with no surgical wound

Risks & complications

More common
  • Pain and soreness in the shoulder for a few days
  • A post-procedure flare of pain, often within the first 24 hours
  • Bruising at the needle sites
  • Calcium remaining on later scans even if pain improves
Less common
  • Feeling faint during the procedure (a vasovagal reaction)
  • Inflammation of the nearby bursa (bursitis) after the procedure
  • Stiffness for a time, or incomplete or temporary pain relief
Rare but serious
  • Infection in the shoulder or bursa, which can be serious and needs urgent treatment
  • Damage to nearby structures from the needle
  • Tendon damage or, very rarely, tendon rupture

Barbotage is usually low-risk for serious harm, but a flare of pain in the first day or two is common, which is why steroid is often given at the same time. Its main limitation is uncertain benefit relative to other treatments and the fact that calcium often partly remains. If a steroid is used, discuss its risks. Choose a clinician who uses ultrasound and sterile technique and who is honest about what the procedure can and cannot achieve.

Published figures to discuss

Reported benefit from barbotage varies between studies and techniques. Older reviews described low complication rates and possible benefit, but a later sham-controlled BMJ trial did not show added benefit from lavage with steroid over sham procedures. Calcium often partly remains on later imaging even when pain improves. Serious complications such as infection are uncommon, but a post-procedure pain flare is common enough to discuss.

These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.

What happens afterwards

There is no surgical recovery — only needle puncture sites. 'Afterwards' is mainly about managing a flare of shoulder pain in the first day or two and gradually returning to movement and rehabilitation as it settles.

First 24 hours
A flare of shoulder pain is common as the area reacts. Use prescribed or simple pain relief, rest the arm and apply a cold pack if advised.
Days 2–7
Soreness and any bruising usually start to settle. Gentle movement is encouraged to avoid stiffness, as advised by your clinician or physiotherapist.
Weeks 2–6
Many people notice pain improving and gradually return to normal use and a rehabilitation programme to restore strength and movement.
6 weeks to a few months
A reasonable point to review how much the pain and function have improved. Calcium may still show on a scan even when you feel better.
What's normal — and not a worry
  • A flare of shoulder pain in the first day or two
  • Soreness and bruising at the needle sites for a few days
  • Gradual improvement in pain over the following weeks
  • Some stiffness that eases with gentle movement and rehabilitation
  • Calcium sometimes remaining on scans despite feeling better

Aftercare

  • Use prescribed or simple pain relief, especially in the first day or two when a flare is common.
  • Rest the arm initially but start gentle movement as advised to avoid stiffness.
  • Return to a shoulder rehabilitation programme to rebuild strength and movement as guided.
  • Keep the needle sites clean and watch for signs of infection.
  • Attend the review to check how much pain and function have improved.
  • Tell your clinician if pain is severe, worsening, or not settling as expected.
Before your procedure
  • Prescribed or simple pain relief to hand for the first day or two
  • A cold pack if advised
  • A shoulder rehabilitation plan to follow
  • A lift home arranged if the shoulder is sore
  • A review date to judge benefit
  • Awareness of infection warning signs
  • An agreed plan if pain does not improve

Scars and how they heal

There is no surgical scar. Barbotage is done through one or two needles, leaving small puncture sites that may be a little sore or bruised for a few days and then settle.

⚠ Get urgent help if…

  • Spreading redness, heat, swelling, fever or feeling unwell — possible infection, seek urgent help
  • Severe or rapidly worsening shoulder pain out of proportion to the procedure
  • Inability to move the arm, or sudden weakness — seek assessment
  • A large or expanding bruise or swelling around the shoulder
  • New numbness, tingling or weakness spreading down the arm
  • Feeling very unwell, hot and shivery in the days after the procedure

Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.

General guidance — it doesn't replace the specific advice your specialist gives you.

Results & realistic expectations

A good result is meaningful pain relief and improved shoulder movement and function, often building over the weeks after the procedure and alongside rehabilitation. Many people improve, but barbotage cannot be promised to remove all the calcium or to cure the problem permanently.

A systematic review found there is not enough good-quality evidence to say barbotage is better than other treatments, and calcium deposits often partly remain on later scans even when pain settles. This is why honest care explains barbotage as an option that helps many but not all, reviews the result, and does not over-promise.

How long it lasts

Pain relief after barbotage is often lasting for those who respond, but calcific tendinopathy can recur and calcium can remain or re-form, so symptoms occasionally return. Keeping up shoulder strengthening and movement gives the best chance of a durable result. Some people need further treatment if the problem comes back.

Related tests, treatments or support

Barbotage is usually combined with a steroid injection into the nearby bursa at the time, and with a shoulder rehabilitation programme afterwards. It may be considered after, or instead of, shockwave therapy. Your clinician should explain how these fit together and why each is recommended.

Follow-up & long-term care

You should have a planned review, often within a few weeks to a few months, to check how much your pain and function have improved. If symptoms persist, the clinician may repeat imaging, consider another treatment, or discuss referral to a shoulder specialist or surgeon. Ongoing rehabilitation is usually part of the plan.

  • Keep up shoulder strengthening and movement exercises after the procedure.
  • Return to overhead or heavy activity gradually as advised.
  • Seek review if pain returns rather than assuming repeated procedures are needed.
  • Address any contributing factors in technique or workload.

Repeat, follow-on and what comes next

  • Calcium frequently remains, at least partly, on scans even when symptoms improve, so a 'normal' scan is not the goal.
  • Some people need a repeat procedure or another treatment if symptoms persist or recur.
  • Persistent or severe symptoms may prompt referral to a shoulder specialist or surgeon.
  • Repeating the procedure should follow an honest review rather than being assumed.

Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.

What good aftercare looks like

  • Clear pain-relief advice for the first day or two, when a flare is common.
  • A shoulder rehabilitation plan to restore movement and strength.
  • A named contact and a planned review of pain and function.
  • Clear infection warning signs and how to seek urgent help.
  • A sensible plan for what happens if symptoms persist, including specialist referral.

What affects the cost

Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:

  • Whether the procedure is charged on its own or with imaging and follow-up
  • That ultrasound guidance is used (and who performs it)
  • Whether a steroid injection is included
  • Whether single- or double-needle technique is used
  • Whether an assessment and any imaging are included or separate
  • Whether shoulder rehabilitation/physiotherapy is bundled or extra
Make sure your written quote includes
  • The cost of the procedure and what it includes
  • That ultrasound guidance and any steroid injection are included
  • Whether the assessment and any imaging are included
  • Whether shoulder rehabilitation/physiotherapy is part of the package
  • What follow-up or review is included
  • The cancellation policy
  • What happens, and what it costs, if it does not help or a complication occurs

On the NHS? Barbotage is available in some NHS services when calcific tendinopathy is painful and not settling; it is also offered privately for speed or choice, with simpler measures usually tried first.

You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.

Choosing a specialist safely

  • Check the specialist is on the GMC Specialist Register for this area.
  • Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
  • You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
  • Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
  • You're entitled to your total cost in writing — including any follow-up — before you decide.

Questions to ask your medical professional

Take this to your consultation. A good specialist will welcome every one of these.

  • Is my calcific tendinopathy stubborn enough to need barbotage, or could it settle with time and rehabilitation?
  • Will you use ultrasound guidance, and a single or double needle technique?
  • Will you inject a steroid at the same time, and what are its risks and benefits?
  • How much pain relief is realistic, and is the calcium likely to clear completely?
  • What should I expect in the first day or two, and how do I manage a flare?
  • What is the plan if it does not help — repeat, other treatment, or specialist referral?
  • Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
  • Will you be the specialist who carries out my procedure, and who looks after me afterwards?
  • What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
  • What does a realistic result look like — and what can this procedure not achieve?
  • What are my options, including waiting, doing nothing for now, or choosing a different approach?
  • Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
  • What is the total cost in writing, including any follow-ups, and how much time do I have to decide?

Frequently asked questions

Does barbotage cure calcific tendinopathy?
It can give useful pain relief and help clear some of the calcium, and many people improve, but it is not a guaranteed cure. A systematic review found limited evidence that it beats other treatments, and calcium often partly remains even when pain settles.
Will the calcium be completely removed?
Often not. The aim is to soften, fragment and wash out as much as possible, but residual calcium frequently remains on later scans. Improvement in pain and function matters more than the appearance on the scan.
Does it hurt, and is there much recovery?
Local anaesthetic is used, but a flare of shoulder pain in the first day or two is common, which is why steroid is often given at the same time. There is no surgical wound, only needle sites, and most people ease back into movement over days to weeks.
Why is a steroid injected as well?
A steroid is commonly injected into the nearby bursa to reduce pain and the chance of a post-procedure flare. Steroid has its own considerations, such as a small infection risk and effects on blood sugar, which your clinician should discuss.
Can I get barbotage on the NHS?
It is available in some NHS services when clinically indicated, and is also offered privately for speed or choice. Simpler measures and rehabilitation are usually tried first, as many cases settle in time. In the UK there is no dedicated national (NICE) guidance on barbotage itself; NICE has published national guidance on shockwave therapy for this shoulder condition, and barbotage is otherwise guided by specialist and society evidence, which is why an honest clinician will be clear about how well it is proven.
What if it does not work?
If pain persists, options include further imaging, a repeat procedure in some cases, other treatments, or referral to a shoulder specialist or surgeon. The next step should follow an honest review, not simply more of the same.
