【摘要】：目的探讨拉萨藏族青少年的指骨各参数随年龄的变化规律；拉萨藏族青少年各指骨指节的相关性；建立适合藏族青少年的身高回归方程和性别判别式。材料随机选择父母均为藏族的健康拉萨青少年1680人（男840人，女840人）为研究对象，年龄13～19岁。将被测者左手放于片盒上，嘱其五指分开，中指中轴与前臂中轴一致，球管焦点对准手背之间，靶片距90cm,以60kV，100mA和0.15s的固定条件，进行常规后前位拍摄X线片，共拍摄男、女左手X线片1680例。方法用Adobe Photoshop软件对扫描到电脑里的指骨X线片按300%的比例，参照刘丰春等所用方法将X片进行测量。测量身高的方法：自头顶到地面垂直距离（用人体测高仪测量）。将所得数据用SPSS17.0软件进行分析处理。结果 1、随着年龄的增长，近节指骨轴长、中节指骨轴长、末节指骨的轴长、正中点宽径值、末节指骨宽径值越大。性别间比较，，15岁以下时，各轴长及宽径值长在性别之间差异不是很显著，但是15岁以后，基本都是男性高于女性，并且差异有统计学意义。 2、各指骨指节长、宽与身高均呈中度或高度正相关，男性和女性的环指近节指长与身高的相关系数最大，男性0.833，女性0.677；通过因子分析，得出5个主要因子；推出5个主要因子与身高的回归方程。 3、指骨各指节的性别判别顺序为：拇指近节长中指远节长中指远节宽环指近节宽环指中节长环指远节长;指骨与身高的性别判别顺序为：身高中指远节长中指远节宽环指近节宽环指中节长环指远节长,判别率分别为80.2％、81.5％、86.1％和86.1％，性别判定准确率高达80%以上。结论通过对藏族青少年指骨X线参数的测量，探讨各指骨指节与年龄的关系，并分析主成分与身高间的内在联系及规律，得出多元回归方程，还有各指骨指节与身高的性别判别分析，得出的逐步判别式，判别率高达80%以上，对藏族人群推断身高及性别鉴定提供参考依据。
[Abstract]:PurposeThe changes of the phalangeal parameters of Tibetan adolescents in Lhasa with age, the correlation of phalangeal joints of Tibetan adolescents in Lhasa, and the establishment of height regression equation and gender discriminant for Tibetan adolescents were discussed.Material1680 healthy Lhasa adolescents (male 840, female 840) with Tibetan parents were randomly selected as subjects, aged 1319 years.The left hand of the subjects was placed on the film box, and the five fingers were told to separate, the middle axis of the middle finger and the middle axis of the forearm were the same, the ball tube focused on the back of the hand, the distance between the target and the target was 90 cm, and the X ray film was taken at the fixed condition of 60 kV 100 Ma and 0.15 s.1680 cases of female left hand X-ray film.MethodThe X-ray films of the phalanx scanned into the computer were measured by Adobe Photoshop software according to the ratio of 300% and according to the method used by Liu Fengchun et al.Height measurement: vertical distance from the head to the ground (measured with a human altimeter).The data are analyzed and processed by SPSS17.0 software.Result1. With the increase of age, the length of proximal phalanx axis, middle phalangeal bone axis, end phalangeal bone axis length, median point width, and distal phalangeal bone width were increased.When the sex is under 15 years old, the difference of axis length and width length between the sexes is not very significant, but after 15 years old, the male is basically higher than the female, and the difference is statistically significant.(2) the length and width of phalanx of each phalanx were positively correlated with height. The correlation coefficient between proximal finger length of ring finger and height of male and female was the highest, 0.833 for male and 0.677 for female, five main factors were obtained by factor analysis.The regression equation between five main factors and height was deduced.3. The order of sex discrimination of phalanx in phalanx was as follows: length of distal segment of thumb, length of distal segment of middle finger, broad ring of distal segment of middle finger, length of middle segment of broad ring finger of proximal segment;ConclusionBased on the measurement of X-ray parameters of phalanx in Tibetan adolescents, the relationship between phalanx and age was discussed, and the relationship between principal component and height was analyzed, and the multiple regression equation was obtained.The discriminant rate of the stepwise discriminant of phalanx and height of phalanx is over 80%, which provides a reference for the estimation of height and sex of Tibetan people.
