Bursitis

At a glance

  • Fluid-filled sacs called bursae act as cushions to protect certain parts of our body.
  • If these sacs are irritated or injured, they can become inflamed.
  • This causes pain, swelling and reddening.
  • If this inflammation is caused by bacteria, you may develop a fever as well.
  • It is important to rest the swollen area. Cold packs and painkillers can help.
  • Cortisone is sometimes injected into the bursa too. Antibiotics or surgery are effective if the inflammation is bacterial.

Introduction

Bursitis is an in one of the small, fluid-filled sacs (bursae) often found near joints in the body. It can be very painful and limit mobility. The inflammation can result when too much pressure is put on one of these sacs (a bursa).

The bursae (the Latin word for "bags") are made of connective tissue and filled with synovial fluid. Like tiny pillows, they cushion parts of the body like the elbows, which are often exposed to friction or pressure. When you prop your elbows on a hard tabletop, the bursa prevents the bone from pressing too hard against your skin. There are over one hundred bursae in the human body, many of them near joints.

Bursitis can also be caused by a – usually bacterial – .

Symptoms

If a bursa becomes inflamed, more fluid will build up inside it than usual. Doctors call this effusion. This leads to swelling that you can feel and see from the outside – especially if the inflamed bursa is right under the skin.

The swollen area hurts when resting, but is especially painful when moved or when pressure is put on it from the outside. It may also feel warm and turn red. The darker your skin is, the harder it is to see this redness. You may also develop a fever and generally feel unwell.

Causes and risk factors

Bursae often become inflamed if they are injured by a heavy blow – for example during a fall – or if they are irritated by too much friction or pressure. For this reason, some jobs are associated with a higher risk of bursitis. Tile installers are a typical example: Their work often involves kneeling on hard floors, so it’s not unusual for them to develop kneecap bursitis. Other jobs that have a higher risk of bursitis include cleaning staff, as well as professionals in carpentry, construction, and landscaping. Working for a long time at a computer or doing some types of sports such as volleyball may also make bursitis more likely.

Germs like bacteria can enter the bursa too, causing there. This may happen due to an injury – but it’s often not possible to tell how the got inside the bursa. People who have weakened immune systems – for example, due to a chronic condition like diabetes – are at increased risk of bacterial .

Sometimes inflammatory diseases such as rheumatoid arthritis and gout spread to the bursae as well, causing bursitis.

Prevalence and outlook

Each year, at least 1 out of 10,000 people develop bursitis on their knees or elbows. One third of these inflammations are caused by a bacterial .

Middle-aged men are often affected. That’s probably because they more commonly have jobs that are associated with a greater risk of bursitis. If the area is rested, the usually goes away within 2 or 3 weeks. Sometimes it remains permanently, though – for example, because the person continues (or has to continue) doing the activity that caused it in the first place. Chronic diseases such as diabetes and rheumatoid arthritis may delay recovery too, or even make the worse.

Diagnosis

Inflamed bursae are easy to spot since they are located just under your skin. They are swollen, painful, and tender to the touch. Reddened, warm skin is also a sign of .

Bursitis most commonly affects the elbows, knees, shoulders, hips and feet.

It is important to find out whether the is caused by . If you have a fever and a wound close to the inflamed area, it is very likely to be a bacterial . In order to check whether that is the case, the doctor can take some fluid from the bursa using a hollow needle (cannula) and have it tested in a laboratory. Blood tests can detect further signs of an or show whether the is being caused by a disease such as gout.

Imaging techniques like ultrasound or x-rays are used to rule out other possible causes of the symptoms, such as bone or joint injuries. They can also help to check whether the bursitis may have already damaged nearby tissue.

Treatment

The most commonly recommended treatments for bursitis involve resting the swollen area and protecting it from further pressure. Things like cold packs or painkillers can help. After the goes away, it’s important to avoid putting too much pressure on the joint to stop bursitis from coming back. For instance, people who often work in a kneeling position can use kneepads to protect their knees. Braces (orthotics) may also be an option. If you aren’t sure whether making changes to your working conditions would be helpful, you can ask for advice – for instance, from an occupational health specialist.

If the bursitis doesn’t get better or comes back despite taking the measures described here, steroids are sometimes injected into the bursa. If the is caused by , it is usually treated with first. If the is severe, doctors often recommend having surgery to remove the bursa right away. Surgery may also be an option if the keeps coming back. Other medication may be needed if the bursitis is caused by a particular medical condition like gout or rheumatoid arthritis.
