Treatment of transverse overcurvature of the nail with a plastic device: measurement of response.

Abstract

Transverse overcurvature of the nail is a painful condition that has been treated by conservative and/or surgical methods. We sought to evaluate the efficacy of a plastic device for treatment of transverse overcurvature of the nail and to use a practical method (plaster mold) to evaluate follow-up of nail widening during and after treatment. Twenty-five patients with transverse overcurvature of the nail were treated with placement of a plastic device. Pain assessment was done on a monthly basis. Nail improvement was evaluated through photographs and measurement of widening by plaster molds. Relief of pain could be determined in almost 100% of the cases in a 3-month period. Widening of overcurvature of the nail occurred in all cases. The plaster mold allowed a practical measurement of improvement in nail shape. The plastic device is an effective, safe, noninvasive, and inexpensive treatment option for overcurved nails. The plaster mold is a practical method to evaluate improvement in nail shape.
