Experimental cadaveric studv of lateral impact of the pelvis in children
Abstract：Objective To study the mechanic response of children's pelvis to lateral impact. Methods Twelve 2-to12-year-old children's cadavers were donated by their relatives for this impact test, dividing into younger group (2 to 4 yearsold, n=6) and elder group (5 to 12 years old, n=6). CT scan and X-ray examination were performed before the impact test, andafter the test, X-ray examination and autopsy were conducted. All the pelvises were impacted at a speed of 7.5 ± 0.5 m/s butfor one at 9.1 m/s. Results All tests showed similar behavior of the pelvis with similar timing and peak viscous criterion (V*C)values. Statistical significance was noted in the maximum V*C and degree of stiffness of the pelvis between the 2 groups(P＜0.05). No injuries occurred in the 2 groups after the impact. Conclusion The pelvic test yields very repeatable pelvic responseamong each group tested.
