“…This was chosen to represent the deformation that would occur in the cartilage resulting from a direct posterior displacement of the sternum, resulting from a posteriorly directed load applied to the mid-sternum in the mid-sagittal plane. This loading method has been used previously to study costal cartilage mechanics targeting automobile impact modelling applications (Forman, del Pozo de Dios, Dalmases et al 2010;Forman and Kent 2011).…”

“…Calcified regions vary in shape, often taking forms of isolated globules, rods extending from the costal or sternal boundaries or shells around the periphery of the cartilage (Stewart and McCormick 1984;Rejtarova et al 2004;Forman and Kent 2011). The magnitude (size) of the calcified regions tends to increase with age, beginning in approximately the third decade of life (Linn and Sokoloff 1965;Teale et al 1989;Bahrami et al 2001;Rejtarova et al 2004).…”

“…Moderate or severe calcification is present in approximately 45% of persons of age 75 or greater (Edge et al 1964;Teale et al 1989). In severe cases, calcified regions can overtake almost the entire volume of the cartilage (Forman and Kent 2011).…”

The costal cartilage often undergoes progressive calcification with age. This study sought to investigate the effects of calcification on the structural mechanics of whole costal cartilage segments. Models were developed for five costal cartilage specimens, including representations of the cartilage, the perichondrium, calcification, and segments of the rib and sternum. The material properties of the cartilage were determined through indentation testing; the properties of the perichondrium were determined through optimisation against structural experiments. The calcified regions were then expanded or shrunk to develop five different sensitivity analysis models for each. Increasing the relative volume of calcification from 0% to 24% of the cartilage volume increased the stiffness of the costal cartilage segments by a factor of 2.3-3.8. These results suggest that calcification may have a substantial effect on the stiffness of the costal cartilage which should be considered when modelling the chest, especially if age is a factor.

The biomechanical response of a human rib cage to cardiopulmonary resuscitation maneuvers was investigated by means of finite element simulations. We analyzed the effect of the location where the force was applied on the achieved compression depths and stress levels experienced by the breastbone and ribs. For compression locations on the breastbone, a caudal shift of the application area toward the breastbone tip resulted in a 17% reduction of the force required to achieve a target 5 cm compression depth. We found that the use of compression regions located on the costal cartilages would involve higher risk of rib fractures.
