Overview of Ultrasound-Guided Barbotage

Hydroxyapatite crystal deposition disease (HADD) is a medical condition where hydroxyapatite (HA) crystals build up in and around the joint areas. It frequently affects the tendons of the rotator cuff, the group of muscles and tendons that surround the shoulder joint. If these crystals cause discomfort in the tendons, the condition is then referred to as calcific tendinitis.

One treatment option used to manage the pain from calcific tendinitis is a procedure called shoulder barbotage. This procedure usually involves an injection of a steroid into the area just under the shoulder blade and the top of the upper arm muscle.

Shoulder barbotage is typically guided by ultrasound, which uses sound waves to create images of the inside of your body. This allows the doctor to see exactly where to place the needle to remove the crystals causing your pain. This method is very important for avoiding injury to other nearby structures in the shoulder.

An important part of the procedure is making the patient feel as comfortable as possible, reducing their pain throughout. It is also crucial that the doctor maintains sterile conditions to prevent any infections after the procedure.

Anatomy and Physiology of Ultrasound-Guided Barbotage

Hydroxyapatite crystal deposition disease (HADD) is a fairly common condition that leads to the development of calcium crystal lumps within and around tendons and other connective tissues. It usually affects people in middle-age and commonly involves the tendons in the shoulder, followed by the hip and spine.

The disease is not fully understood but is thought to have something to do with the degeneration of certain tissues. The development of HADD can be divided into four stages: pre-calcific, formative, resorptive, and post-calcific. The pre-calcific stage involves changing of the collagen fiber structures of a tendon into a different type of tissue called fibrocartilage. The formative stage is characterized by the development of new cells and crystal formation, while the resorptive stage features inflammation. The post-calcific phase involves new blood vessel and collagen formation. Sometimes, the bone underneath can also get affected, leading to cortical erosions and reactions in the surrounding bone surface. In some cases, these crystals can rupture into the surrounding areas, causing painful inflammation and arthritis-like conditions.

Doctors usually identify HADD using special imaging tests like radiographs. In these images, the crystals appear fluffy and round. The shape of the crystals can tell the doctor how long they’ve been in the tissue – well-defined crystals usually mean that they’ve been there for a long time. Special scans called CT (Computed Tomography) can be used to identify this condition, especially if there’s suspicion for a deep tissue infection or trauma. Another type of imaging test, MRI (Magnetic Resonance Imaging), can also be used to identify any inflammation and other associated conditions.

The most common sites for HADD are the tendons of the rotator cuff, a group of muscles and tendons that surrounds the shoulder joint. The crystals often show up on radiographs at or close to the point where these tendons attach to the humerus, or the long bone in your upper arm. In some cases, HADD can be associated with tears in these tendons due to the shared attachment site. A number of fluid-filled sacs, or bursae, surround the shoulder, and the largest of these, the subacromial-subdeltoid bursa, plays a crucial role in a common treatment procedure for HADD which we’ll discuss further.

Ultrasound imaging plays a key role in the treatment of HADD, such as in procedures like barbotage and steroid injection for pain relief. On ultrasound, HADD can appear as bright spots of calcification with a ‘shadow’ behind them, or as nodular bright foci of calcification without any shadowing. The crystals can also appear in multiple, fragmented appearances. Additionally, a cyst-like morphology has been described. In the case of acute inflammation, an increase in blood flow and thickening of the subacromial-subdeltoid bursa can often be seen. The ultrasound-guided barbotage procedure consists of breaking down the crystals within the affected tendon, followed by the removal of the fragmented crystals, which is also accompanied by a steroid injection for further pain relief.

Why do People Need Ultrasound-Guided Barbotage

If you have calcific tendinitis, which is a condition where calcium deposits cause a tendon to become inflamed, your doctor might suggest a few things to help manage your pain. You might be prescribed oral analgesics. These are medicines like ibuprofen that you swallow to help minimize pain.

Other treatment options could include a corticosteroid injection – that’s where a doctor uses a needle to put a medicine called a corticosteroid directly into the inflamed tendon. This aims to lower inflammation and reduce pain. There is also ultrasound-guided barbotage, which is a technique that uses sound waves to break up the calcium deposits in the tendon.

In some cases, your doctor might suggest surgery if other treatments haven’t worked or if your symptoms are really severe. You could even be considered for a treatment option called extracorporeal shockwave therapy. This non-invasive procedure uses sound waves to target the affected area and improve healing.

Your doctor will choose the best treatment based on your symptoms and how previous treatments have worked. Just remember that it’s important to discuss any concerns or questions you may have with your doctor so they can ensure you get the most appropriate treatment for your condition.

When a Person Should Avoid Ultrasound-Guided Barbotage

There are a few situations when a certain medical procedure or treatment should not be carried out. These situations include:

– If there is an infection in a joint, known as a ‘septic joint’.

– If there is a skin infection, or ‘cellulitis’, in the area where the doctor would need to make an incision or insert a needle.

– If the patient has a severe allergic reaction, called ‘anaphylaxis’, or any allergy to the medications that the doctor plans to use for the treatment.

Equipment used for Ultrasound-Guided Barbotage

The equipment used for this procedure can differ slightly based on where the procedure is being done. However, here is a potential list of the items and substances that might be used during the process:

First, items that can keep the procedure area clean and free from germs will be used. These include things like a sterile drape or towels, which help create a “germ-free zone” (also called a sterile field), and a sterilizing solution. A common type of sterilizing solution used is called chlorhexidine.

An ultrasound machine will be used, specifically one with a high-frequency transducer that operates between 5 to 12 MHz. This machine uses sound waves to create images of the inside of your body, which will help guide the procedure.

Lidocaine, usually between 10 to 20 mL, will be used to help numb the area where the procedure is happening. This is a type of anesthetic (medicine that prevents you from feeling pain).

Saline (basically a saltwater solution), typically in the form of 2 to 3 flushes, might be used. An 18-gauge needle may also be employed, depending on the provider’s preference.

Finally, a mixture of betamethasone and bupivacaine will be prepared. These are medications often used in such procedures. The mixture generally contains 1 mL of betamethasone (6 mg/mL) and 2 mL of bupivacaine (0.5%). Betamethasone is a type of steroid that can help reduce inflammation, while bupivacaine is another anesthetic used for numbing. Other steroids like triamcinolone, or anesthetics like lidocaine or ropivacaine, might also be used instead depending on the specific procedure and individual patient needs.

Who is needed to perform Ultrasound-Guided Barbotage?

The medical team for your procedure includes:

1. The healthcare professional who will be doing the procedure. This person is usually a doctor or a qualified medical practitioner trained to carry out specific types of procedures.

2. A sonographer or in some cases, another assistant to the doctor. A sonographer is a healthcare professional who uses special equipment to create images of structures inside your body. These images help the doctor to understand what’s happening inside your body. This person is like the doctor’s extra pair of eyes during the procedure.

Preparing for Ultrasound-Guided Barbotage

If you need to undergo a procedure to treat a tendon in your shoulder, a few steps will be done first. The doctors will begin with a complete check-up and medical history review. They will examine your shoulder thoroughly, and also look for other possible causes of your pain, like infection in the joint. They will also take a blood test to check your white blood cell count and signs of inflammation.

The healthcare providers carrying out your procedure need to be familiar with the detailed structure of the shoulder as seen on an ultrasound. Ultrasound has become the preferred method for treating tendon inflammation in the shoulder. This is because it’s simpler to use and doesn’t involve exposing you to radiation like other methods. With an ultrasound, the doctors can easily spot tiny changes in the shoulder joint, and can check for tears and the amount of calcium buildup within the tendon. Certain parts of your arm and shoulder, such as the bony part of your upper arm and the area around your collar bone and shoulder blade, can serve as reference points to locate the affected tendon.

Before starting the procedure, the doctors should discuss several things with you:

* They will explain the steps involved in the procedure, like using a needle to break down the calcium deposits.
* They will warn you that you might feel pain or significant discomfort during the procedure.
* They will ask about any past medical conditions or surgeries that could change how the procedure will be done.
* They will let you know about possible complications like infection, swelling (usually within the first day), or a tear in the tendon.

Before starting, the doctors will perform an initial ultrasound to confirm and record the presence of calcium deposits within the tendon. A last double-check will be done before starting. The place where they will insert the needle will be cleaned and covered with a sterile cloth. The ultrasound probe will also be covered with a sterile sleeve.

The best position for you during the procedure might be lying down with your arm fully extended. Your arm could be rotated inward or outward, depending on where the calcium deposits are. If you can’t lie down flat, you can also sit in a partly reclined chair.

How is Ultrasound-Guided Barbotage performed

1. To start, an ultrasound is done to find the exact location of the crystals in your body, and the place where the needle will be inserted is marked on your skin.

2. The skin at that spot is then cleaned with a special solution to kill any germs. A sterile cloth is placed around the area to keep it clean.

3. The ultrasound machine has a probe, like a wand, that is used to look inside your body. This probe is covered with a clean cover to keep it sterile.

4. To minimize discomfort, a numbing agent or local anaesthetic, called 1% lidocaine, is used to numb the skin and nearby soft tissues where the needle will be inserted.

5. With the help of live ultrasound images, a needle is gently guided to the spot where the crystals are seen. An attempt is first made to remove the crystals using the needle.

After trying to remove the crystals, a clean saltwater solution is pulsed through the needle. This helps in breaking up the calcium deposits and making it easier to remove them. Multiple samples of the broken-up crystals are visualized to ensure they’ve been adequately removed. The saltwater injection can be continued, even using multiple needles, until a significant amount of calcium has been broken up and removed.

When the process is completed, a small amount of lidocaine can be injected into the area to help numb the remaining crystal deposits. However, a steroid isn’t injected into the tendon, as it could potentially weaken the tendon and lead to its rupture. To help with pain relief, a mixture of betamethasone and bupivacaine is then injected into the space beneath the shoulder muscle. This can help in the case any calcium crystals are released into this area.

Lastly, any bleeding is stopped, and a sterile dressing is applied on the skin where the needle was inserted.

Things to Note:

Sometimes, two needles might be used at the site of the calcium deposits: one needle for injecting the saltwater solution and the other for removing the broken up crystals. If this method is used, an assistant will be required to either hold the ultrasound probe or control one of the needles.

High quality ultrasound machines are often preferred for this procedure as they give a clearer image of the structures close to the skin’s surface. Lower quality machines are generally used for looking at deeper structures like in the abdomen or pelvic region.

There could still be some remaining calcifications after the procedure, but they typically reduce in size over time, and the associated pain also decreases. Inserting and moving the needle can sometimes be challenging due to the rough texture of the calcium deposits.

The calcium often looks like milk or small fragments in the syringe used for the procedure. Ill-defined calcification, which suggests early and acute disease, usually responds well to this procedure.

Possible Complications of Ultrasound-Guided Barbotage

After medical procedures, some people can experience problems. These could potentially include bruising, a hematoma (which is a collection of blood outside of the blood vessels), infections, or sudden intensification of pain. In some medical centres, patients are usually told to arrange for transportation since driving might not be comfortable immediately after the procedure. However, typically, patients can resume driving a day after the procedure, as long as they feel okay to do so. Doctors usually recommend pain relief medication to deal with any discomfort in the days following the procedure.

Additionally, patients could experience inflammation in a part of the body called the bursa (bursitis). This might occur after the procedure and can cause pain and swelling. In very rare cases, there might be a risk of tendon rupture, which is when a tendon, the tough band of fibrous tissue that usually connects muscle to bone, breaks or tears.

What Else Should I Know About Ultrasound-Guided Barbotage?

HADD (Hydroxyapatite Deposition Disease) can happen due to various hormone, gene, or metabolism-related problems. Often, people don’t even realize they have HADD until it shows up during a routine X-ray. The symptoms can vary from person to person – it can cause sudden sharp pain, mild long-term pain, or sudden pain after a period of chronic pain. Some people may also get a fever.

Other indications can be swelling and warmth in the joint area, which can suggest an infection in the joint that needs immediate medical attention. Restricted movement of the joint could also be a symptom. Lab tests might show minor increases in inflammation markers, which are proteins that rise in the body due to inflammation.

The pain usually gets worse when you move and generally occurs just in the affected joint. The pain might even keep you awake at night.

One type of HADD, known as Milwaukee Shoulder, results in a destructive condition of the shoulder joint caused by the tear or deposit of hydroxyapatite crystals. Hydroxyapatite crystals are mineral deposits that can develop around the joints and are often linked to certain types of arthritis.

If this happens in the hands or feet where these crystals deposit in the soft tissues around the joints, it’s referred to as periarticular calcific arthritis.
