Reverse Kirner's Deformity: Case Report

Kirner's deformity is a rare congenital deformity, usually of the little finger, with volar and radial bowing of the distal phalanx. The etiology of this deformity is unclear. We describe a case of a 9-year-old girl with radiographic changes classic for Kirner's deformity but with the curvature and nail changes in the dorsal direction.
