Abstract
A surgical method for expanding a thoracic cage during a surgical procedure includes cutting through a thoracic cage to create an upper thoracic cage portion and a lower thoracic cage portion, separating the first thoracic cage portion and the second thoracic cage portion to open the thoracic cage, and installing, between the first thoracic cage portion and the second thoracic cage portion, a device that holds the first thoracic cage portion and the second thoracic cage portion apart from each other to expand a thoracic cavity of the thoracic cage. The surgical method includes a post-surgical cavity volume of the thoracic cage that is larger relative to a pre-surgical cavity volume of the thoracic cage.
