骨折愈合涉及三个主要方面,即细胞活动、有机母质(包括胶元和基质)形成和无机盐沉积。胶元和基质是骨痂的主要组成部分,它们的形成反映了细胞活动,它们和钙化亦有密切的关系。应用生化方法能测定骨痂中的胶元和基质内各种成分的性质和含量;如应用组织化学方法,则不但能在骨折区将这些成分定位,而且还能看到它们在骨折愈合各阶 Fracture healing involves three major aspects, namely cellular activity, the formation of organic parent material (including collagen and matrix) and the deposition of inorganic salts. Gums and matrix are the main components of callus, and their formation reflects the cell activity, and they are also closely related to calcification. Biochemical methods can be used to determine the callus in the collagen and the matrix of various components of the nature and content; such as the application of histochemical methods, not only in the fracture area will be the location of these components, but also to see them at various stages of fracture healing
