Abstract

A considerable number of congenital malformations result from disturbances of normal fusion of component parts. The ventral midline of the trunk is a common site for such defects, which range from a simple umbilical hernia to multiple defects involving the thoracic and abdominal walls, diaphragm, pericardium, and heart.

An uncommon midline defect occurs when there is partial separation of a portion of the sternum. This is called bifid sternum.
