What is the medical term for an ingrown nail?

The medical term for an ingrown nail is onychocryptosis. This condition occurs when the edge of a nail grows into the surrounding skin, often causing pain, inflammation, and sometimes infection. Onychocryptosis can commonly occur with the toenails, especially if the nails are improperly trimmed or if the shoes are too tight, leading to pressure on the nails.

In contrast, the other terms refer to different conditions. A plicatured nail describes a nail that is folded or has an abnormal shape. Onychomycosis refers to a fungal infection of the nail, leading to thickening, discoloration, and possible detachment. Onychia, on the other hand, is an inflammation of the nail matrix, resulting in nail abnormalities. Each of these conditions affects the nails in distinct ways and is not synonymous with an ingrown nail. Understanding these specific terms is essential for accurate diagnosis and treatment in nail care.
