Retronychia is a rare onychopathy,
occurring in young adults. It is due to a conflict between
the nail plate and the proximal supra-nail fold.
Favouring factors are predominantly microtrauma. The
diagnosis is clinical and confirmed by surgical avulsion,
which also has therapeutic value. We report a case of
retronychia of the nails of the right hand in a 22 year
old man, following immobilisation with a right
anterobrachial-palmar cast.
