What is thoracic insufficiency syndrome?

Also known as: TIS.

The thorax is the portion of the body between the neck and abdomen that includes the spine, and ribs, sternum (breastbone), the chest wall (rib cage), and lungs. TIS is a rare congenital (before birth) complex condition that involves chest wall abnormalities which prevent normal lung growth or breathing.
