What is the appropriate management for an external skin wound caused by a brace in a clinically stable patient?

Management of External Skin Wounds Caused by Braces

Remove the brace immediately and manage the wound with standard wound care principles: thorough irrigation with sterile saline, cautious debridement of any devitalized tissue, topical mupirocin ointment three times daily, and tetanus prophylaxis if vaccination is not current within 5 years. 1, 2, 3

Immediate Brace Removal

• Discontinue brace use immediately upon identification of skin breakdown, as continued pressure will impair healing and increase infection risk. 1, 4
• The brace itself is the causative agent creating localized tissue injury through sustained pressure and friction, making its removal the primary therapeutic intervention. 5
• Re-evaluate whether the brace is medically necessary—many conditions previously thought to require bracing (such as stable spinal injuries) show equivalent outcomes without bracing, eliminating the source of injury entirely. 1, 4

Wound Assessment and Preparation

• Inspect the wound to determine depth, presence of necrotic tissue, signs of infection (erythema, warmth, purulent discharge), and involvement of deeper structures. 1, 6
• Perform copious irrigation with sterile normal saline using a 20-mL or larger syringe to remove bacteria, debris, and any adherent material from the brace. 7, 8, 6
• Avoid high-pressure irrigation as this drives bacteria into deeper tissue layers and can worsen outcomes. 1, 8
• Carefully debride only clearly devitalized or necrotic tissue while preserving all viable tissue to optimize healing. 7, 9, 6

Topical Antimicrobial Therapy

• Apply mupirocin ointment to the affected area three times daily, which can be covered with a gauze dressing if desired. 2
• This provides targeted antimicrobial coverage against common skin pathogens including Staphylococcus aureus and Streptococcus species. 2
• Re-evaluate the patient if no clinical response is observed within 3 to 5 days, as this may indicate deeper infection requiring systemic antibiotics. 2

Tetanus Prophylaxis

• Administer tetanus toxoid if the patient's vaccination is not current within the past 5 years for contaminated wounds or 10 years for clean wounds. 7, 3
• Use Tdap (tetanus, diphtheria, acellular pertussis) if the patient has not previously received it, otherwise use Td (tetanus-diphtheria). 3

Wound Dressing and Protection

• Cover the wound with a clean occlusive dressing to maintain a moist wound environment, which accelerates healing and prevents contamination. 9
• Keep the dressing undisturbed for a minimum of 48 hours unless leakage or strike-through occurs. 8
• Change dressings regularly thereafter based on wound drainage and condition. 9

Pressure Relief and Positioning

• If the brace must be continued for medical necessity, modify or pad it to eliminate all pressure on the wounded area—this is non-negotiable for healing to occur. 1, 5
• Consider alternative immobilization strategies that avoid the injured site entirely. 1
• Elevate the affected area when possible to reduce swelling and accelerate healing. 7, 8

Monitoring for Complications

• Watch for signs of secondary infection including progressive redness, increasing pain, local warmth, purulent discharge, fever, or foul odor. 9
• Pressure ulcers from braces can become polymicrobial infections involving both aerobic organisms (S. aureus, Enterococcus, Proteus, E. coli, Pseudomonas) and anaerobes (Peptococcus, Bacteroides, Clostridium). 1
• If infection develops despite topical therapy, initiate systemic antibiotics and consider surgical debridement for deeper infections. 1, 9

When to Escalate Care

• Obtain surgical consultation if signs of aggressive infection, systemic toxicity, or suspected deeper tissue involvement are present. 9
• Deep tissue involvement or extensive wounds require operative debridement in a surgical setting. 9
• Consider combination surgical and antibiotic interventions for severe or spreading infections. 1

Common Pitfalls to Avoid

• Do not continue brace use over an open wound—this guarantees treatment failure and progression to deeper infection. 1, 4, 5
• Do not rely solely on topical antibiotics for infected wounds with systemic signs—these require systemic therapy. 7
• Do not delay wound care or tetanus prophylaxis, as early intervention prevents complications. 7, 3, 6
• Do not assume the brace is medically necessary without re-evaluation—many bracing indications lack evidence of benefit and only add morbidity. 1, 4
