This work discusses the biomechanical testing of 3 elbow bones, namely the humerus, ulna, and radius. There is a need to identify the mechanical properties of the bones at the organ level. The following tests were performed: 3-point bending, fracture toughness, and axial compression. Six sets of whole-bone samples of human male cadaveric humerus, ulna, and radius (age of donor: 35 to 56 years) were tested. The results were analyzed for statistical significance by 2-stage, repeated-measure analysis of variance (ANOVA). The difference between the bending strength of the humerus, ulna, and radius was statistically significant ( P = .001) when compared to one another. However, the fracture toughness and compressive strength were observed to be similar for the 3 bones. The knowledge of mechanical properties of elbow bones can aid in the design of elbow implants and upper limb protection systems, and also allow us to identify criteria for injury. Further, knowledge of the mechanical properties of the elbow bones can aid in calibrating simulations through finite elements analysis.
本工作讨论了 3 根肘部骨骼（肱骨、尺骨和桡骨）的生物力学测试。需要确定器官水平的骨骼力学性能。进行了以下测试：三点弯曲、断裂韧性和轴向压缩。对 6 组来自男性尸体的整骨肱骨、尺骨和桡骨（供体年龄：35 至 56 岁）进行了测试。通过两阶段重复测量方差分析（ANOVA）对结果进行了统计学意义分析。与彼此相比，肱骨、尺骨和桡骨的弯曲强度差异具有统计学意义（P=0.001）。然而，3 根骨骼的断裂韧性和抗压强度观察结果相似。肘部骨骼机械性能的知识可以帮助设计肘部植入物和上肢保护系统，并有助于确定损伤标准。此外，肘部骨骼机械性能的知识可以通过有限元分析来校准模拟。
