Elbow joint effusion refers to swelling in the elbow joint due to a buildup of fluid. It results from inflammation and can happen for various reasons.
Possible causes of elbow joint effusion include a sprain, fracture, infection, overuse injury, arthritis, or an autoimmune disease. Treatment and recovery times depend on the cause.
In this article, learn more about why elbow joint effusion happens, what to do about it, and what to expect during and after recovery.
What is elbow joint effusion?
An effusion is when fluid collects in the space around a joint. Elbow joint effusion refers to swelling in the elbow joint.
It can result from:
a traumatic injury leading to a sprain or fracture
overuse or repetitive actions, such as in sports
gout, osteoarthritis, and other types of arthritis
an infection, such as septic arthritis
autoimmune disease
In some cases, the swelling may disappear without treatment. However, medical treatment and intervention may be necessary to prevent either permanent damage or a worsening of the condition.
Elbow joint effusion is different from elbow bursitis. The bursa is the fluid-filled sac around the joint. When inflamed, this is known as bursitis.
Doctors can misdiagnose one condition for the other since the bursa is very close to the elbow joint.
Is elbow joint effusion serious?
Minor swelling often disappears without treatment, but more severe or persistent swelling may be a sign of an underlying problem, such as an acute or chronic health condition.
Acute (short-term) conditions, such as fractures and infections, can require urgent treatment. Chronic (long-term) conditions that can cause elbow joint effusion, such as arthritis, may not need immediate treatment.
However, over time, some of the long-term conditions that cause elbow joint effusion may eventually affect the joint, causing difficulty moving or pain. Similarly, continuing to use a joint with an overuse injury may also lead to symptoms worsening.
Anyone who experiences elbow swelling after a traumatic accident or who notices new or severe swelling should seek immediate medical advice. Additional symptoms that need urgent medical attention include:
severe pain
inability to move the joint
a fever and a hot feeling around the elbow, which could be a sign of infection
loss of a pulse
an open fracture or protruding bone
severe bruising, which can indicate internal bleeding
Symptoms of elbow joint effusion
Symptoms of elbow joint effusion include:
pain
swelling
difficulty moving the joint
bruising, in the case of a fracture or sprain
Diagnosing elbow joint effusion
To diagnose elbow joint effusion, a doctor will likely:
ask about symptoms
ask about medical history and any recent incidents that could have triggered the swelling
examine the joint
order an X-ray, CT scan, ultrasound, or MRI
take a sample of fluid from the joint for testing, known as arthrocentesis or joint aspiration
If swelling occurs after a trauma, such as a fall, the joint may be broken. An X-ray can often confirm this, although some fractures may not show up on an X-ray. In these cases, a CT scan may be helpful.
If no trauma has occurred, a doctor may use a CT scan or arthrocentesis to help make a diagnosis. Arthrocentesis gives a sample of the fluid around the joint that doctors can analyze for signs of autoimmune disease.
How do you treat elbow joint effusion?
Treatment of elbow joint effusion depends on the cause.
Fractures
Depending on the severity of the fracture, a doctor may recommend:
using a sling or splint until it heals
taking pain medication to help manage discomfort
resting the joint and refraining from activities, such as heavy lifting
as recovery progresses, exercises to increase motion and rehabilitate the joint
It is essential not to move or exercise the joint until a doctor says it is safe to do so. Moving the joint may move the bones out of place.
In some cases, a person may need surgery to:
remove any fragments of bone from the joint
repair ligaments
use screws or plates to reestablish the joint
replace part or all of the joint
Overuse injury
For people with an elbow overuse injury, or tennis elbow, symptoms usually improve with:
rest
medication
physical therapy
checking any sports equipment to ensure it is suitable for the individual
using a brace
steroid injections, in some cases, to reduce inflammation
Other possible options include platelet-rich plasma injections and shock wave therapy. However, there is not currently enough evidence to prove these are safe or effective.
If symptoms do not improve in 6 to 12 months, a doctor may recommend surgery followed by rehabilitation. It can take 4 to 6 months to recover enough to resume strenuous activities.
Sprain
People can often treat a soft tissue injury at home with RICE:
rest
ice, wrapped in a towel and applied for 10 to 15 minutes to the injury to reduce swelling
compression, such as a Tubigrip
elevation above shoulder level when possible
Nonsteroidal anti-inflammatory medications (NSAIDs), such as ibuprofen, may help manage pain and swelling. However, people should check with a doctor that it is OK to take these first.
Gentle exercise can help with rehabilitation.
Summary
Elbow joint effusion is a swelling of the elbow joint from fluid buildup. Possible causes include a fracture or other damage due to trauma, overuse injury, a sprain, infection, or arthritis.
Treatment depends on why the swelling occurs. In many cases, a full recovery is possible. However, outcomes depend on the cause, the person’s age, and other factors.
Anyone with concerns about a swollen elbow joint should seek medical advice.
