骨是一种复杂的组织，它不断地被破坏并被生物重塑所取代。作为整个骨骼的主要组成部分（作为器官包含其他组织，如骨髓，神经和血管），两种类型的骨组织-皮质骨和小梁骨-具有在运动和剧烈活动过程中承受大量应力的功能任务，如举重或快速跑步。由于骨受到周期性和静态载荷，疲劳和蠕变响应是其力学行为的重要方面。事实上，有证据表明，骨重建的主要刺激是修复由习惯性循环负荷积累的损伤。然而，随着年龄的增长，骨丢失和获得之间的平衡被破坏，骨恶化，导致各种破坏性的临床问题。在现代人群中，骨质疏松症引起的骨折越来越常见，脊柱、髋关节和腕关节是主要部位。用于椎间盘退变和骨关节炎等疾病的矫形假体的植入需要强壮的骨骼进行最佳固定，这对于骨强度可能大大受损的老年脊柱或髋关节等部位来说是一个困难的要求。本章的目的是总结骨作为一种材料的力学行为的亮点。8.
Bone is a complex tissue that is continually being torn down and replaced by biological remodeling. As the main constituent in whole bones (which as organs contain other tissues such as bone marrow, nerves, and blood vessels), the two types of bone tissue—cortical and trabecular bone—have the functional task of withstanding substantial stress during the course of locomotion and strenuous activities such as lifting heavy weights or fast running. Since bones are loaded both cyclically and statically, fatigue and creep responses are important aspects of their mechanical behavior. Indeed, there is evidence that a primary stimulus for bone remodeling is the repair of damage that accumulates from habitual cyclic loading. With aging, however, the balance between bone loss and gain is disrupted, and bone deteriorates, leading to a variety of devastating clinical problems. In modern populations, fractures from osteoporosis are becoming increasingly common, the spine, hip, and wrist being the primary sites. Implantation of orthopedic prostheses for conditions such as disc degeneration and osteoarthritis require strong bone for optimal fixation, a difficult requirement for sites such as the aged spine or hip, where bone strength can be greatly compromised. The goal of this chapter is to summarize the highlights of what is known about the mechanical behavior of bone as a material. 8.
