What does the presence of Onychogryposis indicate regarding nail shape?

Onychogryposis, also known as "ram's horn" nail, is characterized by a thick, curved, and claw-like shape of the nail. This condition often involves excessive curvature and overgrowth of the nail, which can resemble a horn. It typically occurs in older adults or those with certain medical conditions that affect nail growth and health.

The defining feature of onychogryposis is its pronounced curvature, which deviates significantly from the typical nail shapes. The presence of this condition indicates that the nail is not only thickened but also tends to grow in a manner that is markedly different from the standard nail shapes seen in healthy nails.

In summary, the correct answer reflects the unique, curved nature of the nails associated with onychogryposis, emphasizing the disorder's distinct characteristics that lead to this claw-like shape.
