A deformity, dysmorphism, or dysmorphic feature is a major abnormality in the shape of a body part or organ compared to the normal shape of that part.
Causes
Deformity may arise from numerous causes:
- Genetic mutation
- Damage to the fetus or uterus
- Complications at birth
- A growth or hormone disorder
- Reconstructive surgery following a severe injury, e.g. burn injury
- Arthritis and other rheumatoid disorders
- Fractured bones left to heal without being properly set (malunion)
- Chronic application of external forces, e.g. artificial cranial deformation
- Chronic paresis, paralysis or muscle imbalance, especially in children, e.g. due to poliomyelitis or cerebral palsy
