任何对骨骼某些部分重塑的研究都会引发与骨骼作为组织和器官有关的问题。在骨组织中，重塑是生化现象（钙盐的动员）和结构变化的原因，其研究是关于这种重塑的功能意义所表达的不同观点的基础。更长期的假设之一是，重塑是对骨骼所承受的压力所产生的明确需求的反应。对 Wolf 和 Meyer 提出的关于一级骨结构对组织学水平变化的机械意义的定律的可能应用进行的调查使 Gebiiard 11905J 得出结论，骨元及其残余物在承受更大机械应力的区域中更常见：此外，胶原纤维的主要方向根据骨元响应的机械作用而变化。在对骨的微小结构进行的研究中，Filogamo (1945, 1946. 19521) 除其他外表明，施加在肌腱插入区域的强大牵引力负责骨的重新管理。然而，与 Gebiiard 不同的是，这位工作人员报告了相当大的结构紊乱，特别是短 (150/200//) 和不规则的骨和胶原纤维，从一个骨到另一个骨的方向不同，甚至在同一骨的不同区域之间也是如此。其他作者断言，从物理角度来看，由骨及其残余物组成的骨骼比由等量基本薄片形成的骨骼更具抵抗力（Amprino 和 Bairati (19361)。Evans ([1958]：和 Bang (1966，1967])。另一方面，声称骨会降低骨的拉伸强度和弹性模量。此外，在他看来，具有许多小骨的区域较弱Knesf.el ill[1954J] 强调，长骨 Harvesian 系统是按地形排列的，而不是统计上的，这表明机械因素的影响。另一方面，人们注意到骨吸收和沉积过程会导致骨骼矿物质交换，因此骨组织有助于维持体液矿物质稳态。因此，结构重新管理可能部分取决于钙盐持续动员以引入骨组织并暂时储存在骨组织内的需要（Amprino [1938，1948]，McLean 和 Rowland（1963），Neuman 和 Neuman）
Any investigation of the remodelling of some part of t lie skeleton raises problems that are concerned with bone both as a tissue and as an organ. In bone tissue, re modelling is the cause of biochemical phenomena (mobilisation of calcium salts) and structural changes, whose study lies at the foundation of the different views that have been expressed concerning the functional significance of such remodelling. One of the more longstanding hypotheses is that remodelling is a response to definite needs brought into being by the stresses to which the bone thus involved is sub jected. An investigation of the possible application of the laws propounded by Wolf and Meyer for the mechanical significance of first-order bone structures to changes at the histological level led Gebiiard 11905J to the conclusion that osteons and their remnants were more frequent in areas subjected to greater mechanical stress: and moreover, that the main direction of the collagen fibrils varied in accordance with the mechanical action to which the osteons were called upon to respond. In studies carried out on the minute structure of bone, Filogamo (1945, 1946. 19521showed, inter alia, that the powerful traction forces applied in areas of tendon insertion were responsible for bone remanagement. Unlike Gebiiard. however, this worker re ported considerable structural disorder, with particularly short (150/200//) and irregular osteons and collagen fibres that varied in direction from one osteon to another and even between different areas of the same osteon. Other writers have asserted that bone composed of osteons and their remnants is more resistant from the physical point of view than that formed of equal quantities of fundamental lamellae (Amprino and Bairati (19361). Evans ([1958]: and Bang (1966, 1967]). on the other hand, claims that osteons reduce tensile strength and the modulus of elasticity of bone. In addition, areas with many small osteons are weaker in his view than those with a small number of large osteons, because the greater number of cementing lines in the former case are so many extra points of weakness. Knesf. el ill.[1954J have stressed that long bone Harvesian systems are arranged topo graphically rather than statistically, suggesting the influence of mechanical factors. On the other hand, it has been noted that bone resorption and deposit processes result in skeletal mineral exchanges, so that bone tissue is thus a contributor to the maintenance of body fluid mineral homeostasis. Structural remanagement may therefore be supposed to be partly dependent on the need for continuous mobilisa tion of calcium salts for introduction into and temporary storage within bone tissue (Amprino [1938, 1948], McLean and Rowland (1963], Neuman and Neuman
