Pronunciation: sin-DAK-ti-lee
A congenital condition where two or more fingers or toes are fused together, requiring surgical separation.
Full Definition
Syndactyly is a common congenital limb malformation characterized by the partial or complete fusion of adjacent digits. It can be simple (involving only soft tissue) or complex (involving bone fusion). The condition affects approximately 1 in 2,000-3,000 births and may be isolated or part of a genetic syndrome. Surgical separation is typically recommended between 6 months to 2 years of age to optimize hand function and prevent growth disturbances.
Usage
Usage note: Often confused with polydactyly (extra digits); syndactyly refers to fusion of existing digits.
