“…Thoracic injuries are the most frequent after head injuries in terms of the number of fatalities and serious injuries in MVCs [2], and are the most frequent injuries in motorbikepedestrian collisions [3]. The data of estimated Disability Risk (DR) show that older adults had significantly greater overall disability than each of the other age groups, the average DR varies from 50.0 ± 15.4% for older adults to 29.0 ± 13.7% for pediatric patients, in all the age groups of adults the DR >30% [4].…”

Objective. The mechanical properties of ribs from a large number of post-mortem human subjects (PMHS) were analyzed to search for variation according to age, sex or BMI in the sample. A large sample of specimens from different donors (N = 64) with a very wide range of ages and anthropometric characteristics was tested. Methods. Uniaxial tensile tests were used for a sample of coupons machined from cortical bone tissue in order to isolate the purely mechanical properties from the geometrically influenced properties of the rib. Each coupon is about 25 mm long and has a thickness of about 0.5 mm. The mechanical properties measured for each specimen/coupon include YM, yield stress, ultimate stress (maximum failure stress), ultimate strain, and resilience (energy to fracture of SED). The study provides new methodological improvements in DIC techniques. Results. This study is notable for using an atypically large sample of number of PMHS. The size of the sample allowed the authors to determine that age has a significant effect on failure stress (p < 0.0001), yield stress (p = 0.0047), ultimate strain (p < 0.0001) and resilience (p < 0.0001) [numbers in parentheses represent the corresponding p − values]. Finally, there is a combined effect, so that for a given age, an increase of BMI leads to a decrease of the maximum strain (i.e. cortical bone is less stiff when both age and BMI are higher).
