老年股骨近端骨折的生物力学特性及临床应用

近年来，随着人口老龄化的加重，股骨近端骨折的发生率呈明显的上升趋势。随着生物力学软件在医学建模上的应用及发展，利用有限元建模软件对人体骨骼进行生物力学分析及试验，来重建骨的微观结构、分析骨的力学规律成为当前研究的热点。笔者综述了股骨近端骨折的生物力学特性及近年来国内外股骨近端骨折生物力学研究取得的新进展，并结合新进展探讨了其中的一些不足和未来的发展方向，以期更为准确地预测老年股骨近端骨折的发生几率，为指导老年骨质疏松患者的个体化治疗、降低老年股骨近端骨折风险提供指导价值。

The research on biomechanical changes and clinical application of proximal femoral fractures in the elderly

The incidence of proximal femur fractures has shown a significant increase with the aging of the population by years recently. With the application and development of biomechanical software in medical modeling, it has become a hot spot for current research with finite element modeling software for biomechanical analysis, reconstruction of the microstructure bone, and analysis of the mechanical role of the bone. This article reviews the biomechanical characteristics of proximal femur fractures and the new advances in biomechanical research on proximal femur fractures at home and abroad in recent years and discusses some of the shortcomings and future development directions in light of the new advances, aiming to more accurately predict the incidence of proximal femur fractures in the elderly and to provide guidance value for guiding the individualized treatment of elderly patients with osteoporosis and reducing the risk of proximal femur fractures in the elderly.
