Nail abrasion: a new treatment for ingrown toe-nails

A simple new method for the treatment of ingrown toe-nails was devised and applied to 33 toe-nails in 22 patients. The entire nail surface, except for the margin, was abraded until the nail became flexible with a Schreu's skin grinder equipped with a steel bar. When there was infection or granulation of the nail wall, the imbedded nail corner was trimmed before abrasion. The patients underwent additional treatments when one treatment was not enough to achieve cure or when discomfort appeared, which was the first symptom of recurrence. The average number and duration of treatments was 2.9 times and 16 months, respectively. Relief from pain occurred in all patients soon after abrasion was performed. Recurrence of infection and granulation was observed in only one patient. Five patients (23%) remained problem-free for more than one year without any additional treatment, because their incurved nail was gradually improved in shape by repetition of this procedure. This therapy was particularly effective in patients with severely incurved nails.
