中国人四肢长骨骨性标志间各段长度与总长关系的分析

Analysis of the relationship between the whole length of the long bone and the length between the bone marks

利用碎裂的长骨片段 ,计算长骨的总长。选择中国人长骨 5 0 0余例 ,取其骨性标志分段测量记录 ,将测得的数据输入计算机 ,用社会科学软件包 (SPSS)中全回归法进行统计学处理。在得出的 33个多元回归方程中 ,方程1、 9、 18、 2 6证明了骨性标志间各段长度与总长的正相关关系 ,其余 2 9个方程是在有选择的略去 1个变量和因长骨近端、远端或两端缺损使 1个或 1个以上变量缺失的情况下得出。根据碎裂长骨片段骨性标志间的长度测量值 ,应用多元回归方程 。

The present paper aims at calculating the whole length of the long bone by the long bone fragement.More than 500 long bones of Chinese were chosen.The length between the bone marks were measured one by one.Then the data were inputted into the computer and calculated by the statistical regression method from the Statistical Package for the Social Science.Thirty three multiple linear regressions were obstained.A positive relationship between the whole length of the long bone and the length of variable parts between bone marks were proved in the first,ninth,eighteenth,and twenty sixth regressions.The others were obtained under the condition that one or more variables had been left out intentionally.We especially presented the regressions for the long bones which lost either proximal part or distal part, or both of them at once.According to the length measured between the bone marks of the long bone fragment,the whole length of long bone is easy to calculate by means of the regressions developed.
