Abstract
Abstract A method and apparatus for performing pectus excavatum repair on a deformed sternum. The apparatus includes an elongated pectus bar having a first end and a second end. The elongated pectus bar provides a minimum bendable strength of about 65 in-lbs or a minimum material yield strength of 35x106 psi or a minimum bendable stiffness of about 1000 lb-in2. The elongated pectus bar is shaped into a convexly curved pectus bar. The convexly curved bar is passed under the deformed sternum with the convexity facing posteriorly. The elongated pectus bar is then rotated so that the convexity faces anteriorly such that the deformed sternum is raised into a desired position.
