Management of Partially Detached Distal Great Toenail in Children – Evidence‑Based Recommendations

Immediate Conservative Care

Apply a daily topical emollient to the exposed nail bed and peri‑ungual skin to keep the area hydrated and support healing. 1
Clean the site with gentle water‑based cleansers and keep it dry to reduce irritation and infection risk. 1
Dress the foot in comfortable, well‑fitting shoes that provide adequate toe‑box space, thereby avoiding pressure on the injured nail. 1
Use cotton socks rather than synthetic materials to minimise friction on the healing nail bed. 1
Advise avoidance of activities that could cause direct trauma to the nail bed until the new nail plate has sufficiently regrown. 1

If secondary bacterial infection is suspected (e.g., green or black discoloration suggesting Pseudomonas), treat the area with topical povidone‑iodine 2 % twice daily. 2
Observe for signs of paronychia—swelling, erythema, or tenderness of the nail fold—and initiate appropriate antimicrobial therapy if present. 1

Recognise that roughly half of dystrophic nails in children are not caused by fungi; therefore, appearance alone should not dictate antifungal treatment. 4
When the nail becomes thickened, discoloured, or friable over weeks, obtain mycological confirmation (KOH preparation and fungal culture) before starting any systemic or topical antifungal agents. 4

Complete regeneration of a detached distal great toenail may require 3–6 months, varying with the extent of the original injury. 4

Development of significant paronychia or an abscess that necessitates drainage warrants referral to a pediatric dermatologist or hand‑foot specialist. 1
Persistent abnormal nail growth or evidence of nail‑matrix damage after 3–4 months should prompt specialist evaluation. 4
Ongoing nail dystrophy suggestive of underlying dermatologic conditions (e.g., psoriasis, lichen planus) requires referral for further diagnostic work‑up. 4

Do not commence systemic antifungal therapy without laboratory confirmation, as most pediatric nail dystrophies resolve spontaneously and unnecessary medication exposes the child to avoidable adverse effects. 4
