ELBOW,  MUSCULOSKELETAL

Olecranon bursitis 

  • inflammation of the olecranon bursa :  septic or nonseptic
  • male >> female. 30-60 years of age
  • Risk factors
    • sports
    • diabetes
    • uremia
    • manual jobs with elbow use
    • chronic hemodialysis
      • Requires prolonged pressure on the elbow
  • Pathogenesis
    • Nonseptic Bursitis: Acute trauma or repetitive trauma causes inflammation of the olecranon bursa.
    • Septic Bursitis: Infection from microorganisms transferred via trauma to the skin overlying the bursa.
  • Etiology
    • Trauma – acute trauma or repetitive trauma causes inflammation of the olecranon bursa
    • Underlying systemic inflammatory disorder
    • Avulsed osteophyte
    • Infection (20% of cases) – infection from microorganisms transferred via trauma to the skin overlying the bursa
  • Associated conditions
    • rheumatoid arthritis
    • crystalline diseases – e.g., gout or pseudogout
  • Presentation
    • pain or fever may suggest an infectious etiology
  • Physical exam
    • swelling over affected elbow
    • tenderness to palpation
    • erythema, ecchymosis, or abrasions of the skin
    • normal range of motion
  • Imaging
    • Radiography  – to assess for olecranon fracture or osteophyte
    • Findings: Swollen bursa, fracture, or olecranon spurs.
  • Labs
    • indicated only when septic bursitis is suspected – ↑ WCC, ESR
    • Needle aspiration of bursa with Gram stain and culture – if septic bursitis is suspected
    • Aspiration of bursa fluid (Posterolateral triangle)Technique:
      • Patient supine with elbow flexed
      • Mark area of maximal fluctuance for skin entry
      • Aspirate with 22 gauge 1 inch needle
      • Drain fluid
      • Apply pressure dressing after aspiration
  • Treatment
    • NSAIDS
    • Non- septic bursitis
      • Physical therapy
      • rest and ice
      • joint needle aspiration and drainage
      • injected corticosteroids
    • septic bursitis

      • flucloxacillin 1 g (child: 25 mg/kg up to 1 g) orally, 6-hourly.  OR
      • cefalexin 1 g (child: 25 mg/kg up to 1 g) orally, 6-hourly.   OR
      • clindamycin 450 mg (child: 10 mg/kg up to 450 mg) orally, 8-hourly.   OR
      • nonsteroidal anti-inflammatory drugs (NSAIDs)
    • Operative: bursectomy
  • Complications
    • Bursa rupture
    • Osteomyelitis
