桡骨下端骺线与骺软骨板的观测

INVESTIGATION OF THE EPIPHYSEAL LINES AND THE EPIPHYSEAL CARTILAGE PLATES OF THE DISTAL ENDS OF THE RADII

为积累国人桡骨下端骨成熟情况的年龄变化资料 ,作者在成都地区拍摄的 1 0 8个正常人左侧手腕部后前位X线片上 ,对桡骨下端的骺线与骺软骨板进行了观测。结果 :1 .骺软骨板完整 ,即尚未形成骺线者 ,男 :1 8岁 1 5 .3 8% ,1 7岁 4 6.4 3 % ;女 :1 8岁 4 .1 7% ,1 7岁 6.67%。已形成骺线者 ,男 :1 8岁 65 .3 9% ,1 7岁 2 8.5 7% ;女性 :1 8岁91 .67% ,1 7岁 80 .0 0 %。 2 .全部骺线的内侧端都是位于桡骨的尺切迹关节面内。 3 .骺线至桡骨腕关节面的垂直距离 ,男平均为 7.0 5mm ,女为 5 .88mm。 4 .同性别的 1 8岁组与 1 7岁组比较 ,各项测量结果均无显著性差异 (P >0 .0 5 ) ;男和女比较 ,各项测量结果均有高度显著性差异 (P <0 .0 0 5 ) 。

The X ray films of the distal ends of the radii from 108 cases were observed and measured for the epiphyseal lines.The 108 cases consisted of 54 males,26 were 18 years old and 4 were 17 years old,and of 54 females,24 were 18 years old,and 30 were 17 years old.Results:1.the epiphyseal cartilage was complete,that meant the epiphyseal line did not form,the males were 15.38% for the 18 years group,and 46.43% for the 17 years group;the females were 4.17% for the 18 years old group,and 6.67% for the 17 year group.The epiphyseal line has been formed,the males were 65.39% for the 18 years group,and 28.5% for the 17 years group;the females were 91.67% for the 18 years group,and 80.00% for the 17 years group.2.All of the medial ends of epiphyseal lines located in the articular surfaces of the ulnar notch of radii.3.The vertical distances of the epiphyseal lines to the surfaces of wrist joints for males and females were 7.05mm and 5.88mm respectively .4.Comparison showed that there were no significant difference ( P >0.05) among various measurements for 18 and 17 years group of same sex;And that of different sex,there were highly obvious differences,and the measurements for males were all larger than that for females.
