Optimal Management of Dry Diabetic Foot Ulcers

Introduction to Management

The International Working Group on the Diabetic Foot (IWGDF) recommends against using Negative Pressure Wound Therapy (NPWT) in non-surgical diabetic foot ulcers, as it is contraindicated and can cause harm by removing moisture from already dry wounds 1, 2
The American College of Cardiology notes that NPWT is only indicated for post-operative wounds after surgical debridement or amputation, and not for dry, non-exudative diabetic foot ulcers 1, 3, 4

The IWGDF strongly recommends performing aggressive sharp debridement to remove any callus, slough, or necrotic tissue, with a strength of evidence classified as strong (GRADE: strong) 5, 1, 2
Hydrogels are the primary choice for dry wounds, as they facilitate autolysis and maintain moisture, according to the IWGDF guidelines 2
Hydrocolloids can be used as an alternative option, as they absorb minimal exudate while maintaining moisture 2

Total contact cast is the gold standard for plantar ulcers and should be the first-line offloading method, as recommended by the IWGDF 6, 2
If total contact cast is contraindicated, a removable walker rendered irremovable can be used as an alternative 6

Hyperbaric Oxygen Therapy (HBO) may be considered for non-healing ischemic diabetic foot ulcers, but only if the patient has failed standard care after revascularization, with a Class 2b recommendation from the American College of Cardiology 3, 4, 5, 1
The IWGDF recommends against using growth factors, autologous platelet gels, and most bioengineered products in preference to standard care, with a strong recommendation despite the appeal of these expensive therapies 5, 1

The IWGDF recommends a step-wise approach to wound care, including vascular assessment, sharp debridement, application of moisture-retentive dressings, and offloading, with regular reassessment and consideration of adjunctive therapies as needed 6, 5, 1, 2

Continuing NPWT on non-surgical, dry wounds can cause harm and is contraindicated, as noted by the IWGDF 1
Using silver dressings for non-infected wounds is not recommended, as it does not accelerate healing and may cause unnecessary expense, according to the IWGDF guidelines 5, 1
Jumping to expensive biologics before optimizing debridement and offloading is not recommended, as standard care should be prioritized, with a strong recommendation from the IWGDF 5, 1
