What condition involves the lifting of the nail plate from the nail bed without shedding?

Onycholysis is the condition that specifically involves the lifting of the nail plate from the nail bed without any shedding. This can occur due to various factors such as injury, infections, or underlying health conditions. The nail remains attached at the proximal nail fold but separates from the nail bed below. This can create a gap that makes the nail vulnerable to additional issues, such as infections or further damage.

In contrast, onychomycosis refers to a fungal infection of the nail that typically results in discoloration, thickening, and possible distortion of the nail shape, rather than just lifting. Paronychia is an infection of the skin around the nail, which can lead to redness and swelling but does not specifically cause the actual lifting of the nail plate. Athlete's foot is a fungal infection of the skin on the feet and does not relate to the condition of the nails at all. Therefore, the identification of onycholysis highlights a specific alteration in the relationship between the nail and the nail bed, important for understanding nail health and disorders.
