Elbow Bursitis: Causes, Symptoms, and Treatment

Elbow bursitis

Elbow bursitis (olecranon bursitis) is an inflammation of the serous bursa located between the skin and the tip of the olecranon, the posterior bony prominence of the elbow. This condition causes noticeable swelling, often compared to a “golf ball” on the back of the joint, and can be painful or relatively painless depending on the triggering cause. It is one of the most common bursitis conditions of the upper limb, frequent in both work and sports settings.

Anatomy of the Olecranon Bursa

The olecranon bursa is a thin sac filled with synovial fluid that acts as a cushion between the triceps tendon, the skin, and the olecranon bone. Under normal conditions, this structure contains a minimal amount of fluid that reduces friction during elbow flexion and extension movements.

The bursa is located superficially, immediately beneath the skin, which makes it particularly vulnerable to direct trauma and repeated pressure. Unlike deep bursitis in other joints, olecranon bursitis is easily visible and palpable.

Surrounding anatomical structures include:

• Olecranon: the proximal end of the ulna, the insertion point of the triceps
• Triceps tendon: inserts on the posterior surface of the olecranon
• Ulnar nerve: runs in the epitrochleo-olecranon groove, lateral to the bursa
• Skin and subcutaneous tissue: particularly thin in this region

Causes and Risk Factors

Direct trauma

A direct blow to the tip of the elbow can cause bleeding within the bursa, triggering an acute inflammatory response. This mechanism is typical of falls on hard surfaces and contact sports.

Repeated pressure (friction bursitis)

Prolonged resting of the elbow on hard surfaces is the most frequent cause of chronic olecranon bursitis. For this reason, the condition is historically known as “student’s elbow” or “miner’s elbow”. Professionals who work leaning on their elbows (office workers, plumbers, mechanics) are particularly at risk.

Infection (septic bursitis)

Bacteria, most frequently Staphylococcus aureus, can penetrate the bursa through:

• Skin abrasions or wounds on the olecranon
• Insect bites
• Non-sterile local injections
• Hematogenous spread from distant infectious foci

Septic bursitis accounts for approximately 30-40% of cases and requires timely treatment to avoid serious complications such as osteomyelitis or sepsis.

Systemic diseases

Some medical conditions predispose to olecranon bursitis:

• Gout and pseudogout: deposition of urate or calcium pyrophosphate crystals in the bursa
• Rheumatoid arthritis: chronic inflammation with the formation of rheumatoid nodules
• Chronic kidney failure: metabolic alterations that promote inflammation
• Diabetes mellitus: increased risk of septic bursitis due to relative immunosuppression

Main risk factors

Symptoms and Clinical Signs

Aseptic (non-infectious) bursitis

• Swelling: fluctuant swelling on the tip of the elbow, from mild to very voluminous
• Pain: variable, often mild or absent at rest, increases with direct pressure
• Functional limitation: full elbow flexion may be uncomfortable due to skin tension
• Skin: normally intact, without significant redness

Septic (infectious) bursitis

Septic bursitis is distinguished by more aggressive signs:

• Marked skin redness (erythema)
• Evident local heat on palpation
• Intense pain even at rest
• Fever and general malaise
• Lymphangitis: red streaks along the forearm towards the armpit
• Possible wound or skin entry point

Warning signs requiring urgent medical evaluation:

• Fever above 38°C associated with elbow swelling
• Rapidly spreading redness
• Very intense pain with inability to move the elbow
• Purulent discharge from the skin
• Systemic symptoms (chills, malaise, confusion)

Diagnosis

Clinical examination

The diagnosis of olecranon bursitis is predominantly clinical. The doctor evaluates:

• Inspection: localized swelling, redness, presence of wounds
• Palpation: consistency of the swelling (fluctuant, tense, warm), tenderness
• Joint mobility: generally preserved, with possible limitation in full flexion
• Lymph node examination: epitrochlear or axillary lymphadenopathy in the septic form

Fluid aspiration (bursa arthrocentesis)

Puncturing the bursa with fluid aspiration is essential to distinguish the septic form from the aseptic form. The fluid is analyzed for:

• Leukocyte count: high values suggest infection
• Gram stain and culture: identify the bacterial agent
• Crystal search: urate crystals (gout) or pyrophosphate (pseudogout)
• Macroscopic appearance: turbid or purulent fluid in septic bursitis, clear yellow in aseptic form

Instrumental examinations

• X-ray: excludes olecranon fractures, highlights calcifications or bone spurs
• Ultrasound: evaluates bursa size, presence of septa, wall thickness
• Magnetic resonance imaging (MRI): rarely necessary, useful in doubtful or recurrent cases
• Blood tests: complete blood count (CBC), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), uric acid levels to exclude systemic causes

Conservative Treatment

Acute phase

Initial treatment of aseptic bursitis follows the conservative protocol:

Relative rest and protection:

• Avoid resting the elbow on hard surfaces
• Use a protective pad (padded elbow brace)
• Limit activities that cause direct pressure

Cryotherapy:

• Apply ice wrapped in a cloth for 15-20 minutes, 3-4 times a day
• Particularly effective in the first 48-72 hours

Compression:

• Light elastic bandage to contain swelling
• Do not overtighten to avoid ulnar nerve compression

Anti-inflammatory drugs:

• NSAIDs (ibuprofen, naproxen) orally as directed by a doctor
• Topical application of anti-inflammatory gels

Aspiration and infiltration

If swelling is significant and does not respond to conservative measures:

• Aspiration: drainage of fluid from the bursa with a sterile needle, provides immediate relief
• Corticosteroid infiltration: cortisone injection after aspiration to reduce inflammation
• The recurrence rate after aspiration alone is relatively high (30-50%), infiltration reduces it

Treatment of septic bursitis

Infectious bursitis requires a specific approach:

• Antibiotic therapy: orally in mild cases, intravenously in severe cases
• Repeated aspirations: drainage of infected fluid every 24-48 hours
• Surgical incision and drainage: in cases that do not respond to aspiration
• Bursectomy: surgical removal of the bursa in refractory cases

Rehabilitation and Physiotherapy

Goals of the rehabilitation pathway

• Reduce residual swelling and pain
• Restore full elbow mobility
• Prevent recurrences through patient education
• Return to work and sports activities

Phase 1 — Inflammation reduction (weeks 1-2)

Instrumental physical therapy:

• Pulsed low-intensity therapeutic ultrasound
• Laser therapy to stimulate fluid reabsorption
• Post-treatment cryotherapy

Exercises:

• Assisted active mobilization in elbow flexion-extension
• Forearm pronation and supination
• Hand opening and closing movements to promote drainage

Phase 2 — Mobility recovery (weeks 2-4)

Manual therapy:

• Mobilization of radio-ulnar and humero-ulnar joints
• Periolecranon soft tissue release techniques
• Deep transverse massage on the triceps tendon if contracted

Mobility exercises:

• Full elbow flexion-extension (active)
• Wrist flexor and extensor stretching
• Ulnar nerve gliding exercises if associated irritation is present

Phase 3 — Strengthening and prevention (weeks 4-8)

Progressive strengthening exercises:

• Elbow extension against elastic resistance
• Elbow flexion with light dumbbell (1-2 kg)
• Grip and release with balls of different resistances
• Modified push-ups against the wall, then table, then floor

Functional exercises:

• Specific activities for work or sport practiced
• Upper limb proprioception exercises
• Rotator cuff strengthening if necessary (kinetic chain)

Recovery Times

Prevention

Mechanical protection

• Use padded elbow braces during work if elbows are rested
• Wear protections in contact sports
• Place a soft pad when working at a desk

Skin hygiene

• Keep the skin of the elbow clean and hydrated
• Promptly treat abrasions and wounds to prevent infections
• Avoid scratching or irritating the area

Ergonomics

• Vary working position to avoid prolonged pressure
• Adjust desk and chair height to reduce elbow support
• Take regular breaks during repetitive activities

Management of predisposing conditions

• Keep uric acid levels under control in gout
• Follow prescribed therapy for rheumatoid arthritis
• Control blood sugar in diabetic patients

Frequently Asked Questions (FAQ)

Frequently Asked Questions

What is the primary distinction between aseptic and septic elbow bursitis?

Aseptic bursitis typically results from trauma or repeated pressure and is non-infectious. Septic bursitis, conversely, involves a bacterial infection and often presents with additional signs such as redness, heat, intense pain, and fever.

What is the role of a physical therapist in the rehabilitation of elbow bursitis?

A physical therapist guides the rehabilitation process, focusing on reducing inflammation, restoring mobility, and strengthening the affected area. This structured approach aims to facilitate recovery and prevent recurrence through tailored exercises and education.

What preventative measures can be taken to reduce the risk of elbow bursitis?

Prevention involves implementing mechanical protection, such as padding, and maintaining good skin hygiene around the elbow. Ergonomic adjustments and the effective management of any predisposing systemic conditions are also crucial in reducing risk.

Why is fluid aspiration sometimes performed in the diagnosis of elbow bursitis?

Fluid aspiration, or bursa arthrocentesis, is conducted to analyze the fluid within the bursa. This procedure is essential for differentiating between aseptic and septic bursitis, which critically informs the appropriate treatment strategy.
