Correction of Pincer Nail Deformities Using a Modified Double Z-Plasty

BACKGROUND Pincer nail is a deformity characterized by excessive transverse curvature of the nail plate that increases distally for which many conservative and surgical corrective modalities have been recommended. OBJECTIVE The purpose of this study is to investigate the outcomes and safety of modified double Z-plasty in the management of symptomatic pincer nail. MATERIALS AND METHODS Modified double Z-plasty has been performed on 20 great toes in 12 patients from January 2008 to December 2013. The mean age of patients was 43 (range: 20-65) years. Three men and 9 women were enrolled. Visual analogue scale (VAS) score for pain, transverse angle, and width indices were investigated at the initial and the last follow-up. The average follow-up period was 2.4 years. RESULTS All parameters showed significant improvement after surgery. Between the initial and last follow-up, the mean VAS score fell from 7.4 to 0.3, the mean transverse angle improved from 50 to 166 degrees, and the mean width index improved from 65.4% to 97%. In all patients, the deformity was successfully eliminated with no recurrences. No complications were identified. CONCLUSION Modified double Z-plasty provides a long-standing effective treatment for pincer nail deformity with an excellent esthetic result.
