In a biomechanical study we evaluated the stability of human femurs. In order to document the inter- and intraindividual differences in bending stability, we tested 200 bone samples, harvested from the femurs of 5 multiorgan donors. The bending tests were performed on a material testing machine (ZWICK) under standardized conditions. Our results revealed significant differences in the stability of the femurs of the 5 multiorgan donors. Furthermore, there was a significant difference in breaking strength at different levels of the same bone.
In studies aimed at evaluating the primary bony stability of alloimplants after different preservation or sterilization procedures, the above-mentioned results should be taken into consideration.
在一项生物力学研究中，我们评估了人类股骨的稳定性。为了记录个体间和个体内弯曲稳定性的差异，我们测试了从5名多器官捐赠者的股骨中获取的200个骨样本。弯曲测试在材料试验机（ZWICK）上在标准化条件下进行。我们的结果显示，5名多器官捐赠者的股骨稳定性存在显著差异。此外，同一根骨头不同部位的断裂强度也存在显著差异。
在旨在评估不同保存或灭菌程序后同种异体植入物的原发性骨稳定性的研究中，应考虑上述结果。
