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.

受弯曲和压缩载荷影响的男性肘骨生物力学特性的实验评估

这项工作讨论了 3 块肘骨的生物力学测试，即肱骨、尺骨和桡骨。需要在器官水平上识别骨骼的机械特性。进行了以下测试：3 点弯曲、断裂韧性和轴向压缩。测试了六组人类男性尸体肱骨、尺骨和桡骨的全骨样本（供体年龄：35 至 56 岁）。通过两阶段重复测量方差分析（ANOVA）分析结果的统计显着性。与彼此相比，肱骨、尺骨和桡骨的弯曲强度之间的差异具有统计学意义（P = .001）。然而，观察到 3 块骨头的断裂韧性和抗压强度相似。肘骨机械特性的知识可以帮助设计肘部植入物和上肢保护系统，还可以让我们确定受伤的标准。此外，了解肘骨的机械特性有助于通过有限元分析校准模拟。
