Reconstruction of a double nail deformity: a case report.

We report the successful reconstruction of a double nail deformity after fingertip injury. Double nail growth is rather rare. In our case it was not of congenital origin. Double nail deformity results from implantation of the nail matrix associated with damage to the finger tip. We excised the second nail and reconstructed the remaining nail bed using a part of the excised one. The vertical growth of the first nail was also corrected. Four months later, successful regeneration of the nail was observed.
