What is the term for a highly curved nail plate resulting from injury to the matrix?

The term "plicatured nail" refers specifically to a highly curved nail plate that results from an injury to the nail matrix. This condition is characterized by an abnormal shape of the nail, which can occur when the matrix—the tissue under the base of the nail responsible for nail growth—is damaged. This injury affects how the nail plate grows, leading to a pronounced curvature.

In contrast, pseudomonas aeruginosa refers to a type of bacteria that can cause infections, particularly in moist environments, but it does not pertain to the morphology of the nail plate itself. Splinter hemorrhages are small streaks of blood that appear under the nail due to tiny injuries or conditions affecting the blood vessels, but they are not associated with the curvature of the nail. Onychosis is a broader term that encompasses any nail disorder but does not specify the particular characteristic of curvature resulting from matrix injury.

Understanding the definitions and distinctions among these terms is crucial in nail technology, as it facilitates accurate diagnosis and appropriate treatment.
