Syndactyly is a congenital
condition in which two or more fingers or toes are joined together. Sydactyly of the toes is more common that syndactyly of the finger
Syndactyly can be inherited
, and is more common in men than in women. In cases in which the defect is not inherited it can be caused by abnormal conditions in the womb
. It is not usually associated with other birth
In milder cases only the skin of the fingers or toes is joined together, but when more serious, the bones can be fused, and there can even be a shared nail. However the condition can be easily cured by a routine operation in childhood to separate the affected fingers or toes.
