Treatment of Decubital Heel Ulcers
The cornerstone of decubital heel ulcer treatment is complete pressure offloading combined with sharp debridement of necrotic tissue, appropriate wound dressings selected for exudate control, and assessment for vascular insufficiency that may require revascularization. 1
Initial Assessment and Risk Stratification
Vascular Evaluation
- Urgently assess perfusion status by measuring ankle pressure and ankle-brachial index (ABI) in all patients with heel pressure ulcers 1
- Consider urgent vascular imaging and revascularization if ankle pressure <50 mmHg or ABI <0.5 1
- Measure toe pressure or transcutaneous oxygen pressure (TcpO2); consider revascularization if toe pressure <30 mmHg or TcpO2 <25 mmHg 1
- Critical pitfall: Heel ulcers are particularly vulnerable due to limited subcutaneous tissue over the calcaneus, making vascular assessment essential before aggressive treatment 2
Wound Depth Classification
- Determine ulcer stage: superficial (stages I-II involving skin), stage III (involving fat), or stage IV (involving muscle, tendon, or bone) 2
- Stage IV heel ulcers represent 10-20% of cases and often require surgical intervention beyond conservative management 2
- Assess for osteomyelitis in deep ulcers, as underlying bone infection must be ruled out and treated 1
Infection Assessment
- For superficial infection (mild): Cleanse and debride necrotic tissue, start empiric oral antibiotics targeting S. aureus and streptococci 1
- For deep infection (moderate-severe): Urgently evaluate for surgical intervention to remove necrotic tissue and drain abscesses; initiate empiric parenteral broad-spectrum antibiotics covering gram-positive, gram-negative, and anaerobic organisms 1
- Pressure ulcer infections are typically polymicrobial including S. aureus, Enterococcus, Proteus, E. coli, Pseudomonas, Peptococcus, Bacteroides fragilis, and Clostridium perfringens 1
Core Treatment Principles
Pressure Offloading (Absolute Priority)
- Implement complete pressure relief from the heel immediately - this is non-negotiable for healing 1
- Use specialized heel offloading devices, cushions, or positioning aids to eliminate all pressure on the affected heel 1
- Instruct patients to remain non-weight-bearing on the affected heel and use assistive devices (crutches, wheelchair) as necessary 1
- Critical warning: Even optimal wound care cannot compensate for continuing trauma to the wound bed 1
Sharp Debridement
- Remove all necrotic tissue, slough, and surrounding callus using sharp debridement as the preferred method 1
- Repeat debridement as frequently as needed to maintain a clean wound bed 1
- Exercise caution with sharp debridement in patients with severe pain or severe ischemia (relative contraindications) 1, 3
- For large, necrotic, infected wounds, surgical debridement in the operating room can remove devitalized tissue in a single session, significantly accelerating healing 4, 2
Wound Dressing Selection
- Select dressings primarily based on exudate control, comfort, and cost - not on marketing claims 1
- Maintain a moist wound environment to promote autolytic debridement, angiogenesis, and granulation tissue formation 4
- Do NOT use antimicrobial dressings (silver, iodine) solely to accelerate healing - only use when treating active infection 1, 3
- For heavily exudating wounds, consider alginate or hydrofiber dressings 4
- For granulating wounds, polyurethane foams are appropriate 4
Management Based on Healing Progress
Non-Healing Ulcers (After 4-6 Weeks of Optimal Care)
- If ulcer shows <50% reduction after 4 weeks despite optimal management, consider revascularization regardless of initial vascular studies 1
- Reassess for underlying osteomyelitis that may prevent healing 1
- Evaluate for biomechanical factors or deformities requiring surgical correction 1
Advanced Adjunctive Therapies (Only After Standard Care Optimized)
- Consider negative pressure wound therapy for post-operative (surgical) heel wounds to reduce wound size 1
- Consider sucrose-octasulfate impregnated dressings as adjunctive treatment for difficult-to-heal neuro-ischemic ulcers 1
- Consider hyperbaric oxygen therapy for non-healing ischemic ulcers despite best standard care 1
- Consider placental-derived products or autologous leucocyte-platelet-fibrin patch for difficult-to-heal ulcers 1
- Do NOT use negative pressure wound therapy for non-surgical heel ulcers 1, 3
Surgical Interventions for Stage IV Ulcers
Indications for Surgery
- Stage IV heel ulcers with deep tissue involvement often require surgical intervention beyond conservative management 2
- Surgical options include: simple debridement, partial or total calcanectomy, arterial revascularization, or free tissue flaps 2
- Amputation may be required for failed surgical intervention or as first-line treatment in high-risk patients with poor prognosis 2
Interventions to AVOID
The following interventions have strong evidence AGAINST their use and should NOT be employed: 1, 3
- Growth factors, autologous platelet gels (except specific leucocyte-platelet-fibrin patch)
- Bioengineered skin products, autologous skin grafts as routine adjunct
- Topical oxygen therapy, ozone, nitric oxide, or carbon dioxide
- Physical therapies including electricity, magnetism, ultrasound, or shockwaves
- Honey, collagen dressings, alginate dressings, topical phenytoin, or herbal remedies
- Pharmacological agents for perfusion enhancement, vitamin supplementation, or protein supplementation
Critical Pitfalls to Avoid
- Failing to achieve complete pressure offloading - partial offloading is insufficient 1
- Inadequate debridement leaving necrotic tissue or callus in place 1
- Missing underlying vascular insufficiency that requires revascularization 1
- Using antimicrobial dressings without documented infection 1, 3
- Employing advanced therapies before optimizing basic wound care fundamentals 3
- Underestimating the severity of stage IV ulcers that may require surgical intervention 2
