Introduction

Olecranon bursitis, an inflammation of the bursa at the end of the elbow, is a condition that can cause significant discomfort and pain. The olecranon bursa, a small sac filled with synovial fluid, normally acts as a shock absorber between the elbow bone (the olecranon) and the skin, facilitating frictionless movement. However, when this bursa becomes inflamed, the condition known as olecranon bursitis develops.

This inflammation of the bursa can be triggered by several factors, including excessive or repeated pressure on the elbow, excessive movement, direct trauma, infections, or underlying medical conditions such as arthritis. People exposed to activities or occupations that involve regular pressure on the elbows, such as gardeners, plumbers or tennis players, are more likely to develop this condition.

One of the main symptoms of olecranon bursitis is localized pain at the back of the elbow, often accompanied by swelling and tenderness to the touch. Elbow mobility may also be reduced, and discomfort may worsen when putting weight on the elbow or performing certain activities. In some cases, the skin over the inflamed bursa may become red and hot.

The diagnosis of olecranon bursitis is usually based on the symptoms presented by the patient, as well as a thorough physical examination. In some cases, imaging tests such as x-rays or ultrasounds may be done to rule out other possible causes of elbow pain. It is essential to consult a healthcare professional as soon as symptoms appear in order to obtain an accurate diagnosis and an appropriate treatment plan.

Treatment of olecranon bursitis aims to relieve pain, reduce inflammation and prevent recurrence. In mild cases, self-help measures, such as rest, ice application, elbow elevation, and taking nonsteroidal anti-inflammatory drugs (NSAIDs), may be sufficient. However, in more severe or persistent cases, a healthcare professional may recommend additional interventions.

Bursa aspirations, in which accumulated fluid is removed using a needle, may be performed to relieve pressure and reduce swelling. Corticosteroid injections may also be given to reduce inflammation. In some cases, physical therapy may be recommended to strengthen the surrounding muscles and improve elbow mobility.

In situations where olecranon bursitis is caused by an infection, antibiotics may be prescribed to treat the infection. It is crucial to carefully follow the healthcare professional’s recommendations and report any signs of persistent infection, such as increased redness, warmth, or drainage at the site of inflammation.

Preventing olecranon bursitis often involves changing behaviors or habits that may contribute to its development. This may include using appropriate protective equipment, adopting ergonomic techniques at work, and practicing correct movements during physical activities.

In conclusion, olecranon bursitis is a condition that can cause significant pain and discomfort in the elbow area. Management of this condition often involves self-help measures, medical treatments, and in some cases, professional interventions. It is crucial to consult a healthcare professional for an accurate diagnosis and an appropriate treatment plan as soon as symptoms appear.

Causes of Olecranon Bursitis

  1. Trauma or repeated pressure: A direct injury to the elbow, such as a fall or blow, can cause inflammation of the bursa. Likewise, repeated pressure on the elbow, such as frequent leaning on the elbows, can contribute to the development of bursitis.
  2. Excessive rubbing: Excessive or prolonged use of the elbow in repetitive movements, such as rubbing against a hard surface, can irritate the bursa and lead to inflammation.
  3. Infections: Bacterial or, more rarely, viral infections can cause bursitis. Microorganisms can enter the bursa, triggering an inflammatory reaction.
  4. Underlying medical conditions: Medical conditions such as rheumatoid arthritis, gout, or other forms of arthritis can increase the risk of developing bursitis in the elbow area.
  5. Autoimmune disorders: Some autoimmune disorders can cause inflammation of the bursae, including the elbow.
  6. Other causes: Factors such as obesity, advanced age, sports or work injuries, and activities that frequently place stress on the elbow can also contribute to the development of olecranon bursitis.

Symptoms of Olecranon Bursitis

  1. Pain: Pain is the most common symptom. It is usually located at the back of the elbow, just above the protruding bone called the olecranon.
  2. Swelling: Bursitis can cause swelling around the affected area. This can make the elbow thicker and more sensitive to touch.
  3. Redness: Redness of the skin above the bursa may be observed.
  4. Heat: The inflamed area may feel hot to the touch due to increased blood flow and inflammation.
  5. Stiffness: Elbow movement may be limited due to pain and swelling, leading to joint stiffness.
  6. Difficulty bending or extending the elbow: Due to pain and swelling, it may be difficult to perform certain elbow movements.
  7. Increased sensitivity: The affected area may be sensitive to touch, and activities that put pressure on the elbow, such as leaning on it, may be painful.

Pathophysiology of olecranon bursitis

Olecranon bursitis, also known as elbow bursitis, is an inflammation of the bursa located at the back of the elbow joint, between the olecranon bone (end of the elbow) and the skin. This inflammation can be caused by a variety of factors, and the pathophysiology of olecranon bursitis generally involves excessive irritation of the bursa.

Here are the main stages of the pathophysiology of olecranon bursitis:

  1. Irritation and inflammation: The function of the bursa is to reduce friction between the bony, tendon and muscular structures around the elbow joint. Chronic irritation from excessive pressure, repetitive elbow movements, repeated trauma or infections can trigger an inflammatory response.
  2. Inflammatory response: When irritation occurs, cells in the bursa can release inflammatory mediators, such as prostaglandins, thereby causing vasodilation and increased capillary permeability. This causes an influx of inflammatory fluid into the bursa, leading to its enlargement.
  3. Accumulation of fluid: The accumulation of inflammatory fluid in the bursa increases the pressure inside it. This can cause symptoms such as pain, swelling and redness around the elbow.
  4. Formation of thickenings and deposits: Over time, chronic inflammation can cause fibrin deposits to form inside the bursa, which can contribute to thickening of the bursal walls and loss of its normal function.
  5. Limited mobility: Due to pain and inflammation, mobility of the elbow may be limited, and the individual may experience discomfort during arm movements.
  6. Possible Causes: Causes of olecranon bursitis may include direct trauma, excessive friction, bacterial infections, or systemic inflammatory conditions.

Differential diagnosis of olecranon bursitis

  1. Elbow Arthritis: Inflammatory forms of arthritis, such as rheumatoid arthritis, can cause inflammation of the elbow joints, presenting symptoms similar to bursitis.
  2. Elbow tendonitis: Inflammation of the tendons surrounding the elbow, called tendinitis, can also cause pain, swelling and loss of movement similar to bursitis.
  3. Elbow Fracture: A fracture or bone injury to the elbow can cause pain, swelling, and difficulty moving the elbow, symptoms that can be confused with those of bursitis.
  4. Popliteal Cyst: Although more common in the knee, a popliteal cyst can also cause symptoms similar to bursitis, such as swelling at the back of the joint.
  5. Cellulitis: A bacterial skin infection, such as cellulitis, may appear as redness, warmth and swelling around the elbow, resembling the symptoms of bursitis.
  6. Gout: An attack of gout can cause painful inflammation of the joints, including those in the elbow, and can be confused with bursitis.
  7. Elbow tumor: Although rare, a tumor or mass in the elbow can cause symptoms similar to bursitis.

Diagnosis and treatment of olecranon bursitis

Olecranon bursitis, also known as elbow bursitis, is an inflammation of a small pocket of fluid called the bursa located at the back of the elbow, above the olecranon. This condition can be painful and cause localized swelling. Here is an overview of the diagnosis and treatment of olecranon bursitis:

Diagnostic :

  1. History: The doctor will collect information about symptoms, such as elbow pain, swelling, and any recent activity that may be related to bursitis.
  2. Physical Examination: Examining the elbow, including palpation of the affected area, will allow the doctor to determine the precise location of the pain and swelling.
  3. Imaging Tests: In some cases, x-rays or ultrasound may be performed to rule out other conditions or assess the extent of inflammation.

Treatment :

  1. Rest and Avoidance of Activities: Rest is often recommended to reduce inflammation. Avoiding activities that put strain on the elbow can help prevent bursitis from getting worse.
  2. Application of Ice: Applying ice to the affected area can help reduce inflammation. It is generally recommended to apply ice for 15 to 20 minutes every few hours.
  3. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): Medications such as ibuprofen may be prescribed to relieve pain and reduce inflammation.
  4. Compression and Elevation: Wearing a compression bandage can help reduce swelling. Raising the elbow above heart level when possible can also be beneficial.
  5. Aspiration (Fluid Aspiration): In some cases, the doctor may choose to aspirate the fluid accumulated in the bursa using a fine needle.
  6. Osteopathy: Specific exercises may be recommended to strengthen the surrounding muscles and prevent recurrence.
  7. Corticosteroid Injection: In cases of severe bursitis, a corticosteroid injection may be considered to reduce inflammation.

Stretching

Wrist flexor stretch : Hold your arm straight in front of you with your palm facing down. Use your other hand to grip your fingers. Keep your elbow straight and slowly bend your hand back. Your fingers should be pointing up and your palm should be facing away from you. Do this until you feel a stretch in your upper wrist. Hold the position for 10 seconds. Repeat five times.

Wrist Extensor Stretch : This stretch is the opposite of the wrist flexor stretch. Hold your right arm in front of you, palm facing down. Use your other hand to grip your fingers. Keep your elbow straight and slowly bend your hand downward. Your fingers should be pointing down and your palm should be facing you. Do this until you feel a stretch in your wrist. Hold the position for 10 seconds. Repeat five times.

Elbow flexor stretch: Bend your elbow and keep your palm facing you. Use your other hand to gently press on the back of your forearm so that your arm moves toward you. Do this until you feel a stretch in the back of your arm. Hold the position for 15 to 30 seconds. Repeat five times.

Elbow Extension Stretch: This exercise is the opposite of the elbow flexor stretch. Sit in a chair with your arm resting on your thigh. Hold your wrist with the other hand. Slowly straighten your arm so that it is extended as much as possible. Continue to hold your wrist as you slowly move your arm back to the starting position. Repeat 5 times.
