The deformation of distal phalangeal ungues, resulting in an exaggerated curvature, can be attributed to a variety of factors. This alteration in nail morphology presents clinically in diverse manners, ranging from mild arching to severe involuted forms that can cause discomfort and secondary complications.
Addressing the etiology is crucial for proper management and prevention of further exacerbation. Identifying the underlying causes, such as improper trimming techniques, ill-fitting footwear, trauma, fungal infections, or underlying systemic conditions, facilitates targeted intervention. Timely intervention prevents pain, secondary infections, and impaired gait.
