Dysmorphism are characterized by morphological developmental abnormalities such as malformations.
There are various specific types of deformities that can be distinguished.
Madelung's deformity is a malformation of the wrist and wrist bones characterized by a radial deviation of the hand. It is caused by either shortening of the radius or overgrowth of the ulna.
Craniofacial abnormalities include deformations of head and face. It often includes craniosynostosis, the premature fusion of skull plates, which may result in a tower shaped skull.

Characteristically, Madlung deformity develops in mid or late childhood. |

Osteoglophonic dysplasia | |
Dysmorphisms are mainly craniofacial. |

Williams-Beuren syndrome | |
Facial dysmorphic feature include depressed nasal bridge, prominent epicanthal folds, anteverted nares, and prominent lips. |

Skeletal deformities include mesomelic deformities, Madlung deformity of the wrist in particular. |
