A shoulder that hurts when you reach into a cupboard, put on a coat or lie on one side can quickly disrupt work, sleep and exercise. Calcific tendonitis is a relatively common cause of shoulder pain, in such cases a barbotage procedure may be a option for sustained pain relief. It is a minimally invasive, ultrasound-guided procedure used to break up and remove calcium deposits from a tendon, usually the rotator cuff. For suitable patients, it can offer a focused non-surgical treatment when pain and restricted movement are not settling.
What is calcific tendinitis?
Calcific tendinitis, also called calcific tendinopathy, occurs when hydroxyapatite deposits build up within a tendon. It most commonly affects the rotator cuff tendons around the shoulder, particularly the supraspinatus tendon. These tendons help lift and rotate the arm, so even a small deposit can become very troublesome when the shoulder is used repeatedly.
Some calcium deposits cause no symptoms and are found incidentally on an X-ray or ultrasound scan. Others trigger marked inflammation. Pain may start gradually, or it can become suddenly severe during the phase in which the body begins to break the deposit down. People often describe pain over the outside or front of the shoulder, weakness when lifting the arm and disturbed sleep.
The term tendinitis suggests inflammation, but the condition is often better understood as a tendon disorder with calcium deposition. That distinction matters because the right treatment depends on the size, consistency and position of the deposit, as well as the condition of the surrounding tendon and bursa.
Barbotage for calcific tendinitis: how it works
Barbotage is also known as ultrasound-guided needling and lavage. During the procedure, a clinician uses diagnostic ultrasound to locate the calcium deposit in real time. Ultrasound provides much greater precision than treating an area based on symptoms alone, helping to confirm the target and exclude concurrent tendons problems such as a rotator cuff tear.
After cleaning the skin and injecting local anaesthetic, the clinician places a fine needle into the deposit under continuous ultrasound guidance. Saline is gently introduced and withdrawn. This washing process can soften, fragment and aspirate calcium material from the tendon into the syringe. The term lavage refers to this repeated flushing action.
A deposit can vary considerably in texture. Softer, toothpaste-like deposits may be easier to remove. Denser, more solid deposits may not yield much material during the procedure, but needling can still help disrupt the calcium and encourage the body’s natural resorption process. It is not always necessary, or possible, to remove every trace of calcium for treatment to be worthwhile.
In many cases, an ultrasound-guided corticosteroid injection into the subacromial bursa is administered at the same time. This may reduce inflammation and pain around the tendon after the lavage.
Who may benefit from barbotage?
Barbotage is considered for people with a confirmed calcium deposit that corresponds with their symptoms, particularly when shoulder pain is persistent or significantly affecting daily life. It is often most useful when an assessment shows that the deposit is accessible and likely to respond to lavage.
It may be discussed after measures such as activity modification, pain relief, physiotherapy or a previous injection have not provided enough improvement. However, there is no single point at which everyone should have barbotage. A large deposit on imaging does not automatically mean it is causing the pain.
A specialist assessment should also look for other causes of shoulder pain. Rotator cuff tears, bursitis, frozen shoulder, arthritis and referred pain from the neck can produce similar symptoms.
Barbotage may be unsuitable or delayed in some circumstances, including an active skin or systemic infection, certain bleeding risks, an inability to tolerate the procedure under local anaesthetic, or uncertainty about the diagnosis. Medication such as anticoagulants should always be discussed before an intervention. This does not necessarily rule treatment out, but it may change the plan.
What happens at the appointment?
A good barbotage pathway starts with diagnosis, not just the procedure. Your clinician will take a detailed history, examine shoulder movement and strength, and use ultrasound to assess the tendon, calcium deposit and bursa. Previous X-rays, scans and treatment can be useful, but a current point-of-care ultrasound assessment helps guide decisions on the day.
If barbotage is appropriate, the procedure is performed under local anaesthetic. You will be positioned comfortably, often sitting or lying partly on your side. The area is cleaned and prepared carefully. You may feel pressure or brief discomfort from the local anaesthetic and during the needling, but sharp pain should be reported to the clinician.
The treatment itself commonly takes around 10 to 20 minutes, although the overall appointment may be longer because assessment, consent and aftercare all matter. You can usually go home shortly afterwards. Because local anaesthetic can affect comfort and control in the shoulder, it is sensible to arrange for someone else to drive you home where possible.
What recovery should you expect?
It is common for the shoulder to feel more sore for the first 24 to 72 hours. This can happen because the tendon and bursa have been treated directly, and because the body is responding to the disrupted calcium. Simple pain relief and a short period of relative rest can help. Your clinician will advise what is suitable for you, particularly if you have other health conditions or take regular medication.
Most people are encouraged to keep the shoulder gently moving rather than holding it completely still. Heavy lifting, repetitive overhead activity, racquet sports and strenuous gym work usually need to be avoided initially. The appropriate timeframe varies according to your symptoms, the procedure performed and the demands of your job or sport.
Improvement is not always immediate. Some patients notice meaningful relief within days or weeks, while others improve more gradually over months as inflammation settles and the tendon recovers. Follow-up imaging may be useful if symptoms persist, but how you feel and function remains at least as important as the appearance of a residual calcium deposit on a scan.
Benefits, limitations and possible risks
The main benefit of barbotage is its precision. It targets a confirmed calcium deposit without open surgery or a general anaesthetic, and it can often be performed as an outpatient treatment. For the right patient, it may reduce pain, improve movement and support a return to normal activities with less delay.
That said, no procedure can guarantee complete pain relief. A deposit may be too hard to aspirate fully, the shoulder may have another contributing problem, or inflammation may take time to settle. Some people need further rehabilitation, another injection or a discussion about surgical options if symptoms remain substantial despite appropriate non-operative care.
Complications are uncommon but should be considered. These include temporary pain flare, bruising, bleeding, infection, reoccurrence of symptoms and rarely iatrogenic damage to the rotator cuff itself. Steroid injections have their own potential side effects, including short-term changes in blood glucose for people with diabetes. A clinician should explain the expected benefits and the relevant risks in the context of your individual health.
When to seek further advice
Shoulder pain does not have to mean prolonged uncertainty or an immediate route to surgery. A precise diagnosis can show whether a calcium deposit is the real issue and whether barbotage is a sensible next step. The most helpful next move is an expert assessment that gives you a clear explanation, realistic options and a treatment plan built around getting you back to the activities that matter.
