II. Indication

  1. Suspected Septic Bursitis
    1. Standard of care recommendation

III. Background

  1. Rising MRSA rate dictates culture-directed therapy

IV. Technique

  1. Needle: 18-20 gauge
  2. Approach from lateral or distal aspect

V. Complications

  1. Benefit of aspirate findings outweighs risk
  2. Draining sinus development: 6%
    1. Sinuses develop at site other than aspiration site
    2. Implies that sinuses were unrelated to aspiration

VI. Labs for aspirated fluid

  1. Bursal fluid culture
  2. Bursal fluid Gram Stain
  3. Bursal fluid crystal analysis
  4. Bursal fluid cell count with differential
    1. WBC >2000 cells/mm3 suggest septic bursa
    2. WBC <1500 cells/mm3 suggest non-infected bursa
