II. Mechanism
- Often follows acute Trauma
III. Causes
- Staphylococcus aureus (80-85% of cases)
- Streptococcus Pyogenes and other species
- Staphylococcus Epidermidis
- Enterococcus (rare)
- Escherichia coli (rare)
- Pseudomonas aeruginosa (rare)
- Candida (rare)
IV. Risk Factors (present in 50% of cases)
- Diabetes Mellitus
- Chronic Kidney Disease
- Rheumatic disorders
- Alcoholism
- Immunocompromised state
V. Symptoms
- Fever (variably present)
- Bursal pain, redness and swelling
VI. Signs
- Inflammation of skin overlying bursa
- Bursa erythema, warmth, and effusion
- Restricted joint range of motion
- Red flag for deep infection
VII. Labs
-
Complete Blood Count with differential
- May show Leukocytosis with Left Shift
-
Bursa Aspiration
- Bursal fluid PMNs >1000/mm3 suggests Septic Bursitis
- Rising MRSA rate dictates culture-directed therapy
- See Bursa Aspiration
VIII. Imaging
-
Ultrasound indications
- Deep infection suspected
- Guidance for Bursa Aspiration
IX. Management
-
General measures
- Moist heat
- Splinting
- Repeated aspiration or incision, drainage as needed
- Antibiotics
- Cover Staphylococcus and Streptococcus
- Modify antibiotics based on culture of aspirate
- Duration of therapy: 14-21 days
- Shorter courses may be effective, and are not a risk for recurrent infection

- Mild infection
- First-line antibiotics
- Oral: Dicloxacillin
- IV: Cefazolin, Oxacillin or Nafcillin
- Alternatives
- Clindamycin
- Trimethoprim-sulfamethoxazole
- First-line antibiotics
- Severe infection (treat as presumed MRSA)
- Start with Vancomycin IV
- Alternatives: Linezolid, Daptomycin
- Transition to oral agents based on culture results
