Olecranon Bursitis (Elbow Bursitis): Causes, Symptoms and Treatment Options

Olecranon bursitis, commonly referred to as elbow bursitis, is a condition involving inflammation of the bursa located at the tip of the elbow. It often presents as visible swelling over the back of the elbow and may cause discomfort, tenderness, and restricted movement. The bursa is a small fluid-filled sac that helps reduce friction between bone and soft tissues. When this sac becomes irritated or inflamed, fluid can accumulate, causing swelling and sometimes pain.

Olecranon bursitis may develop suddenly following injury or gradually due to repetitive pressure or underlying medical conditions. Early assessment helps determine whether inflammation is simple or related to infection or other causes.

What Is the Olecranon Bursa and Why Does It Become Inflamed?

The olecranon is the bony prominence at the tip of the elbow. Overlying this bone is the olecranon bursa, which allows the skin and soft tissues to glide smoothly over the bone during elbow movement. Because the bursa sits directly beneath the skin, it is vulnerable to irritation, pressure, and injury. When irritated, the bursa produces excess fluid, leading to swelling and inflammation.

What Causes Olecranon Bursitis?

Olecranon bursitis can develop for several reasons, including:

Repetitive Pressure or Irritation - Repeated leaning on the elbows, particularly on hard surfaces, is one of the most common causes. This is sometimes referred to as “student’s elbow.”
Direct Trauma - A fall or blow to the elbow may cause inflammation or bleeding into the bursa, leading to swelling.
Infection (Septic Bursitis) - Bacteria can enter the bursa through small cuts, abrasions, or skin infections. Infected bursitis requires prompt medical attention.

Inflammatory Medical Conditions
Certain systemic conditions can increase the risk of bursitis, including:

Symptoms of Olecranon Bursitis

Symptoms vary depending on whether inflammation is mechanical or infection-related.

Common symptoms include:

Swelling at the tip of the elbow
Tenderness or discomfort when leaning on the elbow
Redness or warmth over the elbow
Reduced elbow movement due to swelling
A soft or fluid-filled lump over the elbow

If infection is present, additional symptoms may include:

Types of Olecranon Bursitis

1

Non-Infective (Aseptic) Olecranon Bursitis

This is the most common type and is usually caused by repetitive pressure, trauma, or inflammatory conditions. It often presents with swelling but minimal pain.

2

Infective (Septic) Olecranon Bursitis

Septic bursitis occurs when bacteria infect the bursa. This type typically causes increased pain, redness, warmth, and may require antibiotics or surgical treatment.

How Olecranon Bursitis Is Diagnosed

Diagnosis begins with a thorough clinical assessment.

Evaluation typically includes:

Review of symptoms and injury history

Physical examination of elbow swelling and tenderness

Assessment for signs of infection or inflammatory disease

In some cases, additional investigations may be required, including:

Ultrasound imaging to assess fluid accumulation

Aspiration (removal of fluid) for laboratory testing if infection is suspected

Blood tests when inflammatory or infectious causes are being considered

X-rays if bone injury or arthritis is suspected

Non-Surgical Treatment for Olecranon Bursitis

Most cases of non-infective olecranon bursitis can be successfully managed without surgery.

Treatment may include:

Avoiding pressure on the elbow
Protective elbow padding or splinting
Ice and anti-inflammatory medication where appropriate
Activity modification
Physiotherapy if movement or strength has been affected

Bursa Aspiration and Injection: In some cases, fluid may be removed from the bursa to relieve swelling and confirm diagnosis. Corticosteroid injections may be considered in selected cases of persistent inflammation.

Treatment for Septic Olecranon Bursitis

When infection is present, treatment focuses on eliminating bacteria and preventing spread.

Early treatment is important to prevent complications.

When Surgery May Be Considered for Elbow Bursitis

Surgical treatment may be recommended when:

Olecranon Bursectomy Surgery

Surgery involves removing the inflamed bursa (bursectomy). The body usually forms a new, healthy bursa during healing.

Surgical treatment aims to:

Rehabilitation may involve:

Most patients return to normal daily activities once swelling and inflammation settle.

Choosing the Right Treatment for Olecranon Bursitis

Treatment depends on several individual factors, including:

Dr Richard Dallalana provides specialist assessment of elbow conditions to determine the most appropriate treatment pathway for each patient.

When to See a Specialist for Elbow Swelling or Bursitis

You may benefit from specialist assessment if you experience:

Early assessment helps confirm diagnosis and supports effective treatment planning.

If you’re experiencing ongoing pain, stiffness, or reduced movement that is affecting your daily activities or quality of life, a thorough orthopaedic assessment can help determine the cause and guide the most appropriate treatment options for your situation.
