Management of Cracked Heels (Heel Fissures)
Cracked heels should be treated by an appropriately trained healthcare professional who can remove excess callus, treat the fissures directly, and prescribe moisturizing therapy, as untreated fissures are strong predictors of foot ulceration, particularly in at-risk populations. 1
Immediate Treatment Approach
Professional Care Required
Heel fissures require immediate professional treatment rather than self-management, as improper treatment can cause harm 1. The IWGDF 2024 guidelines classify fissures as pre-ulcerative lesions that strongly predict future ulceration and must be addressed by trained professionals 1.
Key treatment components include:
- Callus removal: Debridement of excess callus by a trained professional reduces plantar pressure, a critical risk factor for ulcer progression 1
- Direct fissure treatment: Professional management of the cracks themselves to prevent deepening and infection
- Ongoing monitoring: Treatment must continue for the full duration that fissures are present 1
Moisturizing Therapy
After professional debridement, moisturizers containing urea, glycerine, and petrolatum demonstrate significant efficacy for healing deep heel fissures 2. A 2017 randomized controlled trial showed:
- Significantly fewer patients had deep open fissures at 2 weeks (24.7% vs 42.7%, P=0.027) and 4 weeks (6.4% vs 24.1%, P=0.002) compared to placebo
- Significant improvement in xerosis (dryness) at both time points (P<0.001)
- Good tolerability with clinically relevant healing outcomes 2
Application protocol: Apply moisturizer twice daily for at least 4 weeks, though 2 weeks shows measurable improvement 2.
Critical Risk Stratification
High-Risk Populations Requiring Urgent Attention
Patients with diabetes warrant particularly aggressive management, as fissures serve as bacterial entry points that can progress to infection, ulceration, and limb-threatening complications 1, 2. The heel's limited soft-tissue padding and relatively poor vascular supply increase vulnerability, especially in:
- Older adults
- Individuals with diabetes
- Those with peripheral arterial disease 3
In diabetic patients, even minor fissures demand immediate professional intervention to prevent progression to diabetic foot ulcers, which carry significant morbidity and mortality risks 1.
Treatment Algorithm
Initial assessment: Identify depth of fissures, presence of bleeding, infection signs, and underlying risk factors (diabetes, vascular disease)
Professional debridement: Remove all excess callus and treat fissures directly - this is non-negotiable for proper healing 1
Moisturizing regimen: Initiate urea-glycerine-petrolatum based cream twice daily 2
Footwear evaluation: Address pressure points that may be contributing to callus formation and fissure development 1
Weekly reassessment: Monitor healing progress; expect improvement within 2 weeks with appropriate treatment 2
Fungal infection treatment: If concurrent fungal infection present, prescribe antifungal therapy as this is a contributing risk factor 1
Common Pitfalls to Avoid
Do not attempt self-treatment with over-the-counter callus removers or aggressive home debridement - these have potential to cause harm when improperly performed 1. The benefit-harm ratio is only positive when treatment is delivered by appropriately trained professionals.
Do not delay treatment in diabetic patients - what appears as simple cracked heels represents a pre-ulcerative state requiring urgent intervention 1.
Do not discontinue moisturizing therapy prematurely - continue for minimum 4 weeks even if improvement is seen earlier, as incomplete healing increases recurrence risk 2.
