What condition is characterized by the lifting of the nail plate from the bed without shedding?

The condition characterized by the lifting of the nail plate from the nail bed without shedding is onycholysis. This separation occurs between the nail plate and the underlying nail bed, which can be due to various factors such as trauma, fungal infections, or certain skin conditions.

In onycholysis, the nail itself remains intact, meaning it doesn't fall off but is dislodged from its normal attachment point. This distinguishes it from other conditions, such as onychomadesis, where the nail may fully shed due to factors like trauma or illness, or nail psoriasis, which may present with pitting or discoloration but does not specifically involve the detachment seen in onycholysis. Eggshell nails refer to nails that are thin and fragile but do not necessarily involve any lifting from the nail bed.

Understanding these conditions and their specific characteristics helps in identifying and addressing them properly in practice.
