Involuted Nails (Curved Nails)

This has already been mentioned under ingrown toenails.

Curvature of the nail or nails occue due to systemic disease, trauma and tight shoes leave the nail with the edges curving in towards each other, squeezing the flesh in the middle of the nail. This nail requires careful management to keep it compfotable and the sides clear of the sulci.

Occasionally a total nail Avulsion (removal)  is recommended to remove more severe involuted nails, sealing off the nails matrix and not allow the nail to re-grow.
