摘要
本文应用Martin方法,对在西安地区坟墓中收集的213副(男122,女91)中国成人肱骨滑车上孔的出现率、形状、数目和径线进行了调查。结果表明:滑车上孔出现率为11％,女性大于男性,其出现率女性与男性之比为2.29:1。通过比较得知,中国人滑车上孔出现率与日本人、朝鲜人相近,较白种人为高,而比黑种人低。滑车上孔之形状大部分(78.72％)为横椭圆形;在一个肱骨上出现一个滑车上孔者占97.87％。本文还对该孔出现的原因进行了探讨。
This paper presents an investigation on the supratrochlear foramina in 213 pairs of Chinese adult humeri (122 males and 91 females). The data are as follows:1. Bate of appearance: In 47 specimens the supratrochlear foramina were found 11 cases (9%) on the left side and 6 cases (5%) on the right, in 17 males and 15 cases (16%) on both sides respectively in 30 females. The rate of appearance is higher in females than in males (2.29:1). They are located more often on the left side than on the right and found in pairs in 12 cases (51.06%), and non-pairs in 23 cases (48.94).2. Shape: The shape of the supratrochlear foramina is different, but mostly transverse-oval (37 cases, 78.72%). A rounded shape was found in 5 cases (10.46%), polygonal in 3 cases (6.38%) and longitudinal-oval in 2 cases (4.26%).3. Number: One supratrochlear foramen was found in one humerus in 46 cases (97.87%) and two in one case (2.1%).4. Diameter: The longitudinal diameter of the supratrochlear foramina ranged from 1 to 6.85 mm and the transverse diameter from 1 to 10.30 mm.The cause for the appearance of the foramen is discussed.The results of investigation were compared with the data reported by others.
