Unsanitary implements can potentially cause onychia, which is an infection of the nail matrix that leads to inflammation and possibly the loss of the nail. This condition arises when bacteria or fungi are introduced to the nail area through contaminated tools, such as nail clippers or files. The presence of pathogens can create an environment conducive to infection, especially if there are any breaks in the skin or existing nail damage.

In contrast, hyperkeratosis, psoriasis, and athlete's foot are not directly caused by unsanitary implements. Hyperkeratosis involves thickening of the skin or nails due to various factors, typically unrelated to the use of contaminated tools. Psoriasis is a chronic autoimmune condition that affects skin and nails, while athlete's foot is a fungal infection of the skin on the feet, which while it can be influenced by poor hygiene, is not directly a result of unsanitary nail implements. Understanding the connection between proper sanitation and nail health is crucial for preventing conditions like onychia.
