Management of Deep Tissue Injury (DTI) of the Heel
Initial Assessment and Management
- The American College of Cardiology recommends thoroughly assessing the wound to determine depth, extent, and presence of infection, using a sterile blunt probe to measure depth and check for exposed bone 3
- Evaluate vascular status by checking pedal pulses; if pulses are diminished, consider vascular studies (ABI, TcPO2) to determine if revascularization is needed, as recommended by the American College of Cardiology 2, 3
- Assess for peripheral neuropathy using a 10-g monofilament test, as neuropathy affects wound healing and treatment approach, according to Clinical Infectious Diseases 3
Primary Treatment Strategies
Offloading
- Implement immediate pressure relief using appropriate offloading devices, such as heel-relief shoes, as recommended by the American Diabetes Association 1, 4
- Total contact casting or non-removable walkers may be used for severe cases to ensure compliance with offloading, according to the American College of Cardiology 2, 4
Wound Care
- Debride necrotic, non-viable tissue while preserving viable tissue, as recommended by the American Diabetes Association 4, 5
- Apply appropriate wound dressings based on wound characteristics, such as continuously moistened saline gauze for dry or necrotic wounds, according to Clinical Infectious Diseases 6, 4
- Use hydrogels for dry/necrotic wounds to facilitate autolysis, as recommended by Clinical Infectious Diseases 6
- Use alginates for exudative wounds, according to Clinical Infectious Diseases 6
- Use hydrocolloids for absorbing exudate and facilitating autolysis, as recommended by Clinical Infectious Diseases 6
Infection Management
- If infection is present, obtain tissue samples for culture prior to initiating antibiotic therapy, as recommended by Clinical Infectious Diseases 3, 5
- Provide appropriate antibiotic therapy based on culture results, according to Clinical Infectious Diseases 7, 8
- For moderate to severe infections, consider early surgical intervention (within 24-48 hours) to remove infected and necrotic tissue, as recommended by the American Diabetes Association 8
Advanced Treatment Options
Surgical Intervention
- Consider surgical consultation for deep abscesses or compartment syndrome, according to the American Diabetes Association 5
- Consider surgical consultation for necrotizing soft tissue infections, as recommended by the American Diabetes Association 5, 8
- Consider surgical consultation for osteomyelitis with spreading soft tissue infection, according to the American Diabetes Association 5
- Consider surgical consultation for severe ischemia with infection, as recommended by Clinical Infectious Diseases 6, 8
Vascular Assessment and Intervention
- If ischemia is present, urgent vascular specialist consultation is recommended, according to the American College of Cardiology 2, 8
- Revascularization (endovascular or bypass) may be needed before definitive wound management in cases of severe ischemia, as recommended by the American College of Cardiology 2, 5
Monitoring and Follow-up
- Regularly measure and document wound size, extent of surrounding cellulitis, and quality/quantity of drainage, as recommended by Clinical Infectious Diseases 3
- Reassess the wound weekly to evaluate healing progress and adjust treatment plan accordingly, according to the American Diabetes Association 4, 5
- Once healed, implement a comprehensive prevention program to reduce recurrence risk, as recommended by the American Diabetes Association 4
