Management of Recurrent Ingrown Toenail

Initial Assessment and Conservative Trial

• The American Diabetes Association recommends ruling out infection by looking for purulent drainage, significant erythema, or cellulitis that would require antibiotic coverage for Staphylococcus aureus before any procedure, with evidence from the Diabetes/Metabolism Research and Reviews 1
• For diabetic patients, the International Working Group on the Diabetic Foot (IWGDF) suggests providing immediate appropriate treatment by a trained healthcare professional, as ingrown toenails can progress to foot ulceration with significant morbidity, based on evidence from Diabetes/Metabolism Research and Reviews 2, 3, 4

Conservative Management

• The American Podiatric Medical Association recommends antiseptic soaks with dilute vinegar (50:50 dilution) or 2% povidone-iodine for 10-15 minutes twice daily, with moderate-strength evidence from Praxis Medical Insights: Practical Summaries of Clinical Guidelines 5, 6
• The American Academy of Dermatology suggests applying mid- to high-potency topical corticosteroid ointment to the nail fold twice daily to reduce inflammation, with low-strength evidence from Praxis Medical Insights: Practical Summaries of Clinical Guidelines 1, 5

Prevention of Future Recurrence

• The American Diabetes Association recommends proper nail trimming by cutting toenails straight across, never rounded at corners, and avoiding cutting too short, with moderate-strength evidence from Diabetes/Metabolism Research and Reviews and Praxis Medical Insights: Practical Summaries of Clinical Guidelines 1, 4, 5
• The International Working Group on the Diabetic Foot (IWGDF) suggests treating underlying conditions such as onychomycosis with appropriate antifungal therapy if cultures are positive, with high-strength evidence from British Journal of Dermatology and Praxis Medical Insights: Practical Summaries of Clinical Guidelines 5, 7
• The American Podiatric Medical Association recommends hygiene measures including daily foot washing with careful drying between toes, and application of emollients to maintain skin barrier function, with moderate-strength evidence from Diabetes/Metabolism Research and Reviews and Praxis Medical Insights: Practical Summaries of Clinical Guidelines 4, 5, 6

Special Consideration for Diabetic Patients

• The International Working Group on the Diabetic Foot (IWGDF) recommends integrated foot care for diabetic patients at moderate-to-high risk (IWGDF risk 2-3) every 1-3 months, including prompt treatment of ingrown toenails to prevent progression to foot ulceration, with high-strength evidence from Diabetes/Metabolism Research and Reviews 2, 3, 4
• The American Diabetes Association suggests considering extra-depth shoes or custom-made footwear if foot deformities are present, with moderate-strength evidence from Diabetes/Metabolism Research and Reviews 3, 4
