Nail grafts for reconstruction

Monkey digits were used experimentally to demonstrate the pathologic anatomy of nail deformities and the results of treatment using full and partial thickness nail matrix grafts. Seventy-five human nail deformities were evaluated and treated. In both the experimental and clinical groups, microscopic hypertrophy of the superficial epithelial elements underlying the deformed nail existed. A follow-up of treatment of nail deformities indicated that nail matrix grafts, both full and partial thickness, are beneficial when the defect involves the sterile matrix and the proximal nail fold.
