title: Treatment of transverse overcurvature of the nail with a plastic device: measurement of response.
abstract: BACKGROUND
  Transverse overcurvature of the nail is a painful condition that has been treated by conservative and/or surgical methods.
  
  
  OBJECTIVE
  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.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  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.
