| 摘 要： | 本文测量1607例正常儿童青少年第Ⅱ—Ⅳ蹠骨皮质厚度和皮质面积，并计算出三种相对指数。结果表明皮质厚度和皮质面积均随年龄增长逐渐增大，其发育在性别间有差异，其中前者出现两次交叉现象，符合人体发育规律；三种指数在年龄性别间无明显变化。本文认为蹠骨同掌骨一样也是骨量测量的最佳部位，建议最好用皮质厚度结合一种指数的方法判断骨量。本文为代谢性骨病的诊断和生长发育的评价提供了基础资料。

| Abstract: | The cortical thickness and area of the 2nd- 4th metatarsal bones were measured in 1607 cases of normal children and youngsters. Three relative indices were calculated also. The results demonstrated that cortical thickness and area increase gradually with age. There was difference in development in sex. Cortical thickness appeared two crosses and accorded with the development of human body. Three indices had no notable change in age and sex. It is believed that metatarsal bone as metacarpal bone affords the best measuring area of bone quantify and it is suggested that the cortical thickness together with one index is the best method of judging bone quantity. This paper will provide basic data for the diagnosis of metabolic bone disease and the evaluation of growth and development. |
