What is the recommended treatment for dry and ulcerated toenails?

Management of Dry and Ulcerated Toenails

For dry and ulcerated toenails, provide appropriate treatment including daily washing with careful drying, application of emollients for dry skin, and professional debridement of any pre-ulcerative lesions or excess callus to prevent complications and promote healing. 1

Assessment and Initial Management

For Dry Toenails:

• Wash feet daily with clean water or saline
• Dry carefully, particularly between toes
• Apply emollients containing 10% urea at least twice daily to moisturize dry skin 1, 2
• Consider nightly Epsom salt foot baths to soften hyperkeratotic tissue 2
• Apply moisturizer immediately after foot baths to restore skin barrier function 2

For Ulcerated Toenails:

• Clean ulcers regularly with clean water or saline
• Debride necrotic tissue and surrounding callus when possible 1
• Select appropriate dressings based on wound characteristics:
  • For dry/necrotic wounds: hydrogels or continuously moistened saline gauze
  • For exudative wounds: alginates or foams 2
• Dress with sterile, inert dressing to control exudate and maintain a warm, moist environment 1

Treatment Approach Based on Severity

For Mild Cases:

1. Daily foot hygiene with careful washing and drying
2. Regular application of emollients
3. Proper nail trimming (straight across) 1
4. Appropriate footwear that accommodates foot shape and fits properly 1

For Moderate to Severe Cases:

1. Professional sharp debridement of excess callus and necrotic tissue 1
2. Consider silicone or semi-rigid orthotic devices to reduce excess callus 1, 2
3. Assess for underlying conditions:
   • Check for fungal infection (may require antifungal treatment) 3
   • Evaluate for peripheral arterial disease if healing is poor 1
4. For ingrown toenails, consider appropriate treatment including cotton wisps under lateral nail edge or surgical approaches for severe cases 4

Footwear Recommendations

• Wear properly fitted shoes that accommodate foot shape 1
• Avoid walking barefoot, in socks without shoes, or in thin-soled slippers (both indoors and outdoors) 1
• For patients with foot deformities or pre-ulcerative lesions, consider:
  • Extra-depth shoes
  • Custom-made footwear
  • Custom-made insoles
  • Toe orthoses 1, 2

Monitoring and Follow-up

• Monitor for signs of infection or inflammation
• Check for underlying blisters or ulceration
• Evaluate peripheral circulation, especially in diabetic patients 2
• Schedule follow-up in 1-3 months to assess:
  • Response to treatment
  • Need for additional professional debridement
  • Proper footwear fit 2

Special Considerations

For Diabetic Patients:

• More frequent monitoring (every 1-3 months for high-risk patients) 1
• Consider self-monitoring of foot skin temperature once daily to identify early signs of inflammation 1
• Provide integrated foot care including professional care, adequate footwear, and structured education 1
• Be more conservative with debridement in patients with poor circulation 2

For Fungal Infections:

• Confirm diagnosis through appropriate nail specimens (KOH preparation, fungal culture, or nail biopsy) 3
• For confirmed onychomycosis, consider oral terbinafine (250 mg daily for 6 weeks for fingernails, 12 weeks for toenails) 3
• Topical treatments like efinaconazole 10% solution may be effective but have lower complete cure rates than oral therapy 5

Patient Education

• Instruct on proper foot inspection, especially between toes 2
• Educate about signs that require immediate medical attention (increased redness, warmth, pain, or discharge) 1
• Advise limiting standing and walking until healing occurs 2
• Warn against using over-the-counter chemical callus removers 2

Common Pitfalls to Avoid

• Neglecting to assess vascular status before aggressive debridement
• Using antimicrobial dressings with the goal of improving wound healing (not recommended) 1
• Walking barefoot, even indoors
• Inadequate moisturizing of dry skin
• Failing to address underlying mechanical causes of callus formation

By following this comprehensive approach to managing dry and ulcerated toenails, you can effectively promote healing, prevent complications, and improve patient comfort and quality of life.
