本文是将１０个成人干桡骨分别等分为１６段，以骨段为单位研究桡骨内有机质和无机质的含量。结果如下：（１）１６０个骨段平均含有机质３６．２３％，无机质６３．７７％；（２）桡骨近侧端和远侧端有机质的含量明显地高于其它骨段的含量（Ｐ＜０．０５）；（３）桡骨骨干各段的无机质含量明显地高于骨两端的含量（Ｐ＜０．０５）；（４）骨干各相邻骨段之间的无机质含量无显著性差异（Ｐ＞０．２）；（５）第１４段骨的无机质含量明显地高于第１５段骨的无机质含量（Ｐ＜０．０２）．第１４段骨距桡骨下端２．８６－４．２ｃｍ，正好位于Ｃｏｌｌ’ｓ骨折常见的发生部位，该部位的这一结构特点可能是桡骨下段易于发生骨折的原因之一。
In this paper, 10 adult radial and radial bones were divided into 16 segments, respectively, to study the bone within the radius of the organic and inorganic content. The results were as follows: (1) The content of organic matter in the proximal and distal radius was significantly higher than that in other segments (P <0.05). (3) The content of inorganic matter in each section of the radial backbone was significantly higher than that in the both ends of the bone (P <0.05). (4) There was no significant difference (P> 0.2). (5) The content of inorganic matter in the fourteenth section was significantly higher than that in the fifteenth section (P <0.02). The fourteenth segment is 2.86-4.2 cm below the radius from the radius, which is located in the common site of Coll’s fracture. The structural feature of this segment may be one of the causes of fractures in the lower radius segment.
