Brittle nail, simple chronic paronychia, and onycholysis represent three of the most prevalent nail disorders. Brittle nails are characterized by increased fragility of the nail plate due to damage to the nail matrix or changes to nail plate cohesion, caused by internal and/or external factors. Simple chronic paronychia represents an inflammatory process of the lateral and/or proximal nail folds of the fingernails or toenails often preceded by damage to the cuticle. Onycholysis describes the detachment of the nail plate from its nail bed, often attributable to dermatologic conditions, infections, drug therapy, or trauma.
脆性指甲、单纯性慢性甲沟炎和甲分离是三种最常见的指甲疾病。脆性指甲的特征是由于内部和/或外部因素导致甲母质受损或甲板内聚力改变，导致指甲板的脆性增加。单纯性慢性甲沟炎是指甲的侧缘和/或近端甲褶的炎症过程，通常在甲小皮受损之前发生。甲分离是指甲板从甲床分离，通常归因于皮肤病、感染、药物治疗或创伤。
