Abstract: Rib replacement may be required during chest wall reconstruction performed after chest wall resection and malignancy. Present repair techniques can be very rigid and cumbersome and affect patients' respiration.

Abstract: Human ribs are angulated. There are changes in rib angulation that occur with body growth. Rib angulation was correlated with the vectors of chest wall forces estimated by an ellipsoid biomechanical model using finite element analysis.

Abstract: Auxetics are materials that exhibit a negative Poisson's ratio i.e. they expand when pulled apart. This makes auxetic materials are more resistant to fracture. Also auxetic materials do not dent easily-when compressed, the material compresses towards the point of impact and becomes much denser.

Abstract: Dehiscene of median sternotomy wounds remains a clinical problem. Sternal forces can be calculated by thin shell theory and this data may be used to guide optimal wire placement in the sternum during median sternotomy wiring.
