Webbed Fingers (or toes); properly called SYNDACTYLY, a deformity present at birth and which tends to run in families. The web may be quite a thin structure, or the fingers may be closely united by solid tissue. In any case, separation is a matter of considerable difficulty, because, if the web is simply divided, it heals up as before. Surgery is necessary to turn back a flap of the web upon each of the united fingers, or some other device to encourage healing in the new position.
