Dr. Jacoby describes nail lifting, as well as onychoschizia and onychomadesis.
Nail lifting has a medical term called onycholysis, which means the nail lifts up off the nail plate; lots of reasons for that – micro trauma, athletic endeavors, some type of macro trauma, but probably the most common is fungus. Fungus gets under the nail plate and burrows its way back and loosens the nail off the plate.
You also can see bacterial infections. I think another interesting onycholysis is HIV infections. HIV infections produce a yeast-like infection, not at the distal aspect of the nail plate, but more at the proximal nail plate and that is pathognomonic of early AIDS diagnosis.
Onychoschizia and onychomadesis – two funny sounding names for similar conditions. Schizia is more of a groove in the central portion of the nail, probably due to trauma, maybe it’s due to congenital malformation. Madesis is the term for callus nail borders, very painful by the way, probably most commonly from tight-fitting shoes. It looks like and feels like an ingrown toenail, but is really just a callus nail border.
