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°, 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.
