AB Key  PointsMedial  deviation  of  finger  at  distal  interphalangeal  joint.  Fifth  finger  most  commonly  affected.Not  an  anomaly.  Usually  due  to  developmental  delay  or  arrest.Present  in  1%  of  normal  individuals,  but  also  found  in  60%  of  newborns  with  Down  syndrome.Associated  with  many  genetic  syndromes.A  detailed  fetal  ultrasound  evaluation  should  be  performed.  If  clinodactyly  is  isolated,  karyotype  is  not  indicated.  If  an  additional  anomaly  is  found  on  a  detailed  scan,  obtain  a  fetal  karyotype.Isolated  clinodactyly  can  be  inherited  as  an  autosomal  dominant  trait.
