Treatment of Non-Pressure Buttock Ulcer
For a non-pressure skin ulcer on the buttock, initiate proper wound cleansing with normal saline, perform debridement of any necrotic tissue, apply appropriate moisture-retentive dressings, and consider systemic antibiotics only if there are signs of spreading cellulitis or systemic infection.
Initial Assessment and Wound Care
The first priority is determining whether infection is present. Look specifically for:
- Spreading erythema beyond the wound margins (cellulitis)
- Purulent drainage
- Systemic signs (fever, elevated white blood cell count)
- Pain disproportionate to wound appearance (suggests deeper infection)
Cleanse the wound with sterile normal saline—avoid iodine or antibiotic-containing solutions as these can impair healing 1. Remove superficial debris gently without aggressive debridement that could enlarge the wound 1.
Debridement Strategy
If necrotic tissue is present, debridement is indicated 2. The approach depends on urgency:
- Urgent sharp debridement: Required if advancing cellulitis or sepsis is present 2
- Non-urgent methods: Mechanical, enzymatic, or autolytic debridement for stable wounds without systemic signs 2
After debridement, maintain appropriate wound dressings to keep a moist healing environment 2.
Antibiotic Decision Algorithm
Do NOT routinely use antibiotics for clean, non-infected wounds 2. The specific indications are:
- Topical antibiotics: Consider only if no healing improvement after 14 days of proper wound care 2
- Systemic antibiotics: Use when there is:
- Advancing cellulitis
- Osteomyelitis (suspect if pain near bone/joint)
- Systemic infection signs 2
If systemic antibiotics are needed and the wound is polymicrobial (common in buttock ulcers), cover both aerobic and anaerobic organisms 3. Consider local MRSA prevalence—if >20% in your area, include MRSA coverage 3.
Common Pitfalls to Avoid
- Don't close infected wounds—this traps bacteria and worsens outcomes 1
- Don't use first-generation cephalosporins or clindamycin alone if polymicrobial infection is suspected, as anaerobic coverage may be inadequate 1
- Don't perform aggressive debridement on stable wounds—this can impair skin closure 1
- Don't forget to assess for underlying systemic conditions that impair healing (diabetes, vascular disease, immunosuppression, chronic infections like hepatitis C) 4
Adjunctive Measures
- Elevation: If the area is swollen, elevation accelerates healing 1
- Nutrition assessment: Provide supplementation if deficiencies are identified 2
- Address underlying causes: Since this is NOT a pressure ulcer, investigate other etiologies (trauma, infection, vasculitis, metabolic conditions) 5, 4
Follow-Up Timing
Monitor within 24 hours either by phone or office visit 1. If infection progresses despite appropriate antimicrobial and wound care, hospitalization should be considered 1.
