Pincer Nail Deformity: Clinical Characteristics, Causes, and Managements

Abstract EN

A pincer nail is a common nail deformity of toenails and is characterized by nail thickening and nail plate deformation.

It often causes severe pain for patients.

We perform a thorough literature review and an additional review of pertinent clinical cases, aiming to provide a comprehensive review of the etiology, pathogenesis, clinical classification, differential diagnosis, and treatment of pincer nail deformity (PND).

Understanding the clinical characteristics and treatment progress of a pincer nail will provide clinicians with comprehensive and evidence-based information about PND, thus allowing the selection of an appropriate treatment according to the patient’s request and the clinical manifestations of PND, which should maximize patient satisfaction.
