Isolated Types
Brachydactyly is a congenital anomaly that can present as an isolated malformation or as part of a complex malformation syndrome. Isolated brachydactyly may have accompanying subtle changes in other areas of the body. This anomaly may also be associated with other hand malformations, including syndactyly, polydactyly, reduction defects, and symphalangism.
