国人胸骨的形态测量

Morphological measure on the Chinese sternum

目的 提供胸骨测量与观察的地方性资料 ,为临床胸骨穿刺术提供形态学资料。方法 采用 10 1例内蒙古通辽地区出土的成年人干燥胸骨标本 ,70例经过福尔马林固定的胸部湿标本 ,使用游标卡尽测量 ,肉眼观察。结果 胸骨长(137 0 3± 2 0 2 0 )mm ,胸骨柄长 (48 17± 6 0 4 )mm ,柄最大宽 (5 3 96± 7 2 5 )mm ,柄最小宽 (2 9 5 6± 5 35 )mm ,柄厚 (12 5 7±1 4 6 )mm ,柄前皮质厚 (1 2 3± 0 14 )mm ,柄后皮质厚 (1 2 0± 0 12 )mm ,体长 (87 5 9± 2 3 6 2 )mm ,体最大宽 (31 6 7± 6 5 7)mm ,体厚 (13 6 9± 6 2 8)mm ,体前皮质厚 (1 2 8± 0 15 )mm ,体后皮质厚 (1 2 3± 0 13)mm ,胸骨体前软组织厚 (2 0 4± 0 4 6 )mm。胸骨长宽指数 2 3 1,胸骨体长宽指数 36 1,胸骨体柄长指数 5 5 0 ,胸骨宽厚指数 4 2 5 ,胸骨长柄长指数 35 2。胸骨柄体分离 79例占 78 2 % ,带有胸骨体裂孔 7例占 6 9% ,带有骨性剑突 10例 ,占 9 8%。结论 本组胸骨长与柄长、体长之间有高度相关性(P <0 0 1)。

Objective In order to offer local morphological sternum datas for clinical sternum nyxis. Methods All 101 cases of adults dryed sternum samples from buryed in Tongliao area of Inner Mongolia and 70 cases of wet samples fixed in formalin were observed and measured with vernier. Results The lenth of the sternum was (137 03±20 20)mm;the lenth of the manubrium of sternum was (48 17±6 04)mm;maximum width of the manubrium was (53 96±7 25)mm;minimum width of the manubrium was (29 56±5 35)mm;the thickness of the manubrium was (12 57±1 46)mm;thickness of the front cortex of manubrium was (1 23±0 14)mm;thickness of the back cortex of manubrium was (1 20±0 12)mm;the lenth of the body was (87 59±23 62)mm;waximum width of the body was (31 67±6 57)mm;thickness of the body was (13 69±6 28)mm;thickness of the front cortex of the body was (1 28±0 15)mm;thickness of the back cortex of the body was (1 23±0 13)mm;thickness of the front soft tissue of the body of sternum was (2 04±0 46)mm;index of the lenth and width of sternum was 23 1;index of the lenth and width of sternum body was 36 1;index of lenth of manubrium of sternum was 55 0;index of width and thickness of sternum was 42 5;index of lenth of long manubrium of sternum was 35 2;79 cases with separated on sternum body and manubrium occupied 78 2%. 7 cases with separated sternum body was 6 9%. 10 cases with bony xiphoid proccess was 9 8%. Conclusion It show there is a high correlation among the lenth of the sternum,manubrium and the body of sternum(P<0 01).
