pin·cer nail

transverse overcurvature of the nail that increases distally, causing the lateral borders of the nail to pinch the soft tissue with resulting tenderness; may result from a developmental anomaly or subungual exostosis.

The age-related changes that are common--thickened, yellowed, brittle nails, and deformation resulting in ingrown nails or severe curvature of the nail plate ("pincer nails") (5)--do not permit the achievement of a therapeutic goal of clear or almost clear nails, or even, in some cases, an appreciable improvement in appearance.
This is according to researchers at the University of Nottingham who have devised equations to identify the physical laws that govern nail growth, and used them to throw light on the causes of some of the most common nail problems, such as ingrown toe nails, spoon-shaped nails and pincer nails.
