Olecranon Bursitis
Upper LimbOverview
Olecranon bursitis is inflammation of the bursa located between the olecranon process and overlying skin at the posterior elbow. This common condition can result from trauma, repetitive pressure, or infection, presenting with swelling, pain, and reduced elbow function. Early intervention typically resolves symptoms, though chronic cases may require more aggressive management.
Pathophysiology
The olecranon bursa is a fluid-filled sac that reduces friction between the olecranon process and skin. Inflammation occurs through either traumatic rupture with hemorrhage, chronic repetitive pressure (leaning on elbows), or infectious seeding (typically Staphylococcus aureus). Non-infectious cases involve synovial inflammation with fluid accumulation, while septic bursitis involves bacterial proliferation within the bursa, potentially leading to abscess formation and systemic infection.
Patient Education
Avoiding direct pressure on the affected elbow and modifying activities that stress the posterior elbow are crucial for recovery; most cases resolve within weeks with conservative management, though persistent swelling may require aspiration or injection.
Typical Presentation
Site
Posterior elbow over the olecranon process; swelling may extend into the forearm
Quality
Dull, aching pain; localized tenderness; sometimes sharp pain with direct pressure or certain movements
Intensity
Mild to moderate pain; often 3-5/10 at rest, increasing with elbow flexion/extension or direct trauma
Aggravating
Direct pressure on posterior elbow, leaning on elbows, repetitive elbow flexion-extension, contact sports, pushing activities
Relieving
Rest, ice application, elbow padding, anti-inflammatory medications, elevation, avoiding direct pressure
Associated
Visible posterior elbow swelling (may be fluctuant), limited elbow range of motion, erythema, warmth (if infected), regional lymphadenopathy (if septic), possible systemic signs in infectious cases (fever, malaise)
Orthopaedic Tests
Olecranon Bursa Palpation
Procedure
With the patient's elbow flexed to 90°, palpate directly over the olecranon process at the posterior elbow to detect swelling, warmth, fluctuance, or tenderness.
Positive Finding
Localized swelling, fluid bulge, warmth, or point tenderness directly over the olecranon bursa
Sensitivity / Specificity
Unknown / Unknown
Interpretation
Direct palpation is the primary clinical assessment for bursal distension and inflammation; positive findings support olecranon bursitis diagnosis, particularly when combined with history of direct trauma or pressure.
Elbow Flexion Range of Motion Assessment
Procedure
Passively and actively flex the patient's elbow from full extension to full flexion, noting any pain, restriction, or end-feel abnormality.
Positive Finding
Pain at the posterior elbow during flexion, particularly near end-range, or restriction of flexion ROM
Sensitivity / Specificity
Unknown / Unknown
Interpretation
Limitation or pain with flexion may indicate bursal inflammation causing mechanical restriction or pain with compression of the distended bursa.
Pressure/Compression Test (Olecranon Bursa Compression)
Procedure
Apply direct pressure to the distended olecranon bursa with the elbow in various positions of flexion (45°–90°), or compress the bursa and ask the patient to flex/extend the elbow.
Positive Finding
Reproduction of pain or discomfort with direct compression or movement under compression
Sensitivity / Specificity
Unknown / Unknown
Interpretation
Pain with compression suggests active bursal inflammation and increased intra-bursal pressure; helps differentiate bursitis from other posterior elbow pathology.
Lying Prone Olecranon Pressure Test
Procedure
Position the patient prone with the arm hanging off the table or the elbow flexed at 90° over the table edge; apply moderate pressure to the olecranon bursa and observe for pain or restriction.
Positive Finding
Pain or tenderness with sustained pressure over the bursa in prone position
Sensitivity / Specificity
Unknown / Unknown
Interpretation
Reproducing symptoms in a position that increases bursal pressure supports bursitis; useful for distinguishing inflammatory bursal pathology from other causes of posterior elbow pain.
Ultrasound Imaging Assessment
Procedure
Real-time ultrasound of the posterior elbow with the patient supine or prone; visualize the olecranon bursa in longitudinal and transverse planes, assessing bursal thickness, fluid content, and echogenicity.
Positive Finding
Bursal thickening (>3 mm), hypoechoic or anechoic fluid collection, or hyperemia on power Doppler
Sensitivity / Specificity
86–95% / 80–90%
Interpretation
Ultrasound is highly sensitive and specific for detecting bursal inflammation, fluid accumulation, and hyperemia; confirms clinical diagnosis and can differentiate septic from aseptic bursitis when combined with clinical presentation.
Bursal Aspiration and Fluid Analysis
Procedure
Under sterile conditions (preferably ultrasound-guided), aspirate fluid from the distended olecranon bursa using an 18–25 gauge needle; analyze fluid for cell count, crystal analysis, Gram stain, and culture.
Positive Finding
Clear or yellow serous fluid (aseptic bursitis); purulent fluid with positive Gram stain or culture (septic bursitis); monosodium urate or calcium pyrophosphate crystals (crystal-induced bursitis)
Sensitivity / Specificity
95–100% (for septic vs. aseptic differentiation when culture positive) / 95–100%
Interpretation
Gold standard for determining bursal fluid composition and ruling in/out infection; essential when septic bursitis is suspected clinically or when bursa is warm, erythematous, or systemically ill patient; guides treatment (antibiotics vs. conservative care).
⚠ Red Flags
- •Signs of septic bursitis: fever, systemic malaise, rapidly progressive swelling, purulent drainage, severe pain disproportionate to examination
- •Cellulitis or spreading erythema suggesting deep space infection
- •Severe trauma with neurovascular compromise or open wound
- •Immunocompromised patients with any signs of infection
- •Inability to achieve full elbow extension suggesting mechanical obstruction
- •Trauma with fracture of olecranon process on imaging
⚡ Yellow Flags
- •Repetitive occupational exposure (plumbers, miners) suggesting chronic irritation and potential for recurrence
- •Patient belief that swelling indicates serious pathology increasing anxiety
- •Secondary gain from disability (work absence, compensation claims)
- •Psychosocial stress potentially affecting pain perception and recovery
- •History of recurrent bursitis suggesting maladaptive movement patterns or biomechanical dysfunction
Osteopathic Techniques
Region
Posterior elbow and olecranon bursa
Technique
Soft Tissue
Rationale
Gentle soft tissue mobilization of the bursa and surrounding fascia reduces inflammation, improves lymphatic drainage, and decreases pain without exacerbating acute swelling; essential in early inflammatory phase
Region
Elbow joint (proximal and distal radioulnar joints)
Technique
Articulation
Rationale
Gentle pain-free articulation maintains joint mobility, prevents stiffness, and promotes synovial fluid nutrition to cartilage while avoiding aggravation of the bursa
Region
Cervical and thoracic spine with focus on segments C5-T1
Technique
MET
Rationale
Muscle energy techniques address cervical and thoracic dysfunction that may alter upper limb mechanics and perpetuate compensatory stress on the elbow; restores optimal neural mobility
Region
Shoulder girdle, rotator cuff, and scapular stabilizers
Technique
Soft Tissue
Rationale
Releasing tension in shoulder muscles improves glenohumeral mechanics and reduces abnormal stress transmission to the elbow, addressing proximal dysfunction causing distal compensation
Region
Forearm flexors and extensors, particularly extensor carpi radialis and triceps
Technique
MET
Rationale
Addressing muscular tension in forearm and elbow extensors reduces traction forces on the olecranon process and decreases pressure within the bursa during movement
Region
Lymphatic structures of upper limb and axilla
Technique
Lymphatic
Rationale
Enhancing lymphatic drainage reduces inflammatory exudate within the bursa, promotes resolution of edema, and supports immune clearance of inflammatory mediators
Add-On Approaches
Chinese Medicine
Acupuncture at local points (TE10/Shousanli, TE8/Sanyangluo) and distal points (LI10/Quchi) combined with herbal anti-inflammatory formulas (e.g., containing Bupleurum or Curcuma) support inflammation resolution and pain modulation through qi-blood circulation enhancement
Chiropractic
Chiropractic care may include adjustment of cervical and thoracic spine to optimize neurological function, coupled with soft tissue manipulation of elbow and upper limb; however, direct bursa manipulation should be avoided
Physiotherapy
Progressive range of motion exercises, eccentric strengthening of elbow extensors, scapular stabilization training, and postural correction address biomechanical dysfunction; avoid resistance exercises during acute inflammation
Remedial Massage
Gentle remedial massage to shoulder, upper arm, and forearm muscles reduces tension and improves circulation; posterior elbow should receive only light effleurage initially, progressing to deeper soft tissue work as inflammation resolves
