利用颅骨额中缝进行个人识别1例

根据颅骨骨缝构型的同一认定,国内外已经进行过不少这方面的研究。颅骨骨缝的构型如同指纹,各不相同;颅骨骨缝的构型不仅在同一个体的不同部位有所不同,即使在同一骨缝也可存在不同的构型[1]。各颅骨缝愈合的年龄不同,其中额中缝通常愈合年龄较早,像额中缝未愈合的情况在正常成     

单一大关节判定男性青少年骨龄可靠性的比较研究

通过男性青少年单一关节X线片判定年龄是快速、简便的一种方法,但这些方法哪一种更准确尚无系统研究。本文研究了100例正常男性青少年X线片(13~18岁)对单一大关节判断年龄的结果进行了初步比较,结果发现在不同年龄段每种方法的准确性是不同的。在15~16岁之前,百分位数法、CHN法、肩关节法、肘关节法和腕关节法准确性更高些。在15~16岁之后,六大关节法、膝关节法、踝关节法和髋关节法的准确性更好。     

关于上颌牙弓性别差异的研究

利用自动显示游标卡尺测量200例（男、女各100例，年龄18～24岁）上颌石膏模型上牙弓宽、长及高等18个指标。经统计分析发现除切牙弓长、尖牙间距对应高及第二双尖牙间距对应高外，其余15项测量指标男性均大于女性（P＜0．05）。逐步判别分析仅用7个测量指标，判别率可达到75．50％。

目的通过计算骨骼计算机断层扫描(Computed Tomography,CT)三维重建图像判定性别和推断年龄的准确率,评价利用骨骼CT三维重建图像判定性别和推断年龄的可行性。方法将法医人类学教材中性别判定和年龄推断的方法应用于539例骨骼CT三维重建图像样本,判定245例骨盆的性别,推断100例男性耻骨联合、100例男性胸骨和94例男性锁骨的年龄,计算准确率。结果骨盆性别判定准确率为98.4%,耻骨下角和坐骨大切迹是区分性别最好的两项指标。男性耻骨联合、胸骨、锁骨的年龄推断准确率在45%以上,其中锁骨双侧方程准确率最高为77%。结论利用骨骼CT三维重建图像判定性别和推断年龄具有可行性。使用大体标本建立的骨盆形态学性别判定方法可直接应用于骨骼CT三维重建图像。使用大体标本建立的男性耻骨联合、胸骨、锁骨形态学年龄推断指标、分级和评分标准以及方程需要修改和补充。     

男性青少年X线片的骨骺特征及年龄推断

根据骨骺的愈合程度推断青少年年龄。本文对河南周口地区 2 10名 13～ 2 0周岁的男性青少年拍摄了左侧肩、肘、腕、髋、膝、踝关节的X线片。对上述关节的近端及远端骨骺进行观察分析 ,选取与年龄变化关系密切的2 7项骨骺愈合指标。并对其进行分级、评分 ,用SPSS软件进行统计学处理 ,建立了多关节骨骺愈合程度推断男性青少年年龄的多元回归方程。选取了其中 4个复相关系数最高 (r =0 75 8～ 0 787) ,且标准误最低者 (SE =1 0 136～1 0 70 1)的多元回归方程。根据多个关节的骨骺愈合情况综合评价判定青少年的年龄 ,可提高年龄判定的准确性。     

Development of the femur--implications for age and sex determination

Growth of four variables of the femur (diapyseal length, diaphyseal length plus distal epiphysis, maximum length and vertical diameter of the head) was analyzed by polynomial regression for the purpose of evaluating its significance and capacity for age and sex determination throughout the entire life continuum. Materials included in analysis consisted of 346 specimens ranging from birth to 97 years of age from five documented osteological collections of Western European descent. Linear growth was displayed by each of the four variables. Significant sexual dimorphism was identified in two of the femoral measurements, including maximum length and vertical diameter of the head, from age 15 onward. These results indicate that the two variables may be of use in the determination of sex in sex determination from that age onward. Strong correlation coefficients were identified between femoral size and age for each of the four metric variables. These results indicate that any of the femoral measurements is likely to serve as a useful source to estimate sub-adult age in both archaeological and forensic samples.

Determination of male age at death in Chinese Han population: using quantitative variables statistical analysis from pubic bones

Determination of age at death by skeletal features is difficult, but important, both in forensic and physical anthropology. Pubic symphysis is a widely accepted morphological indicator, which provides the best result for personal age identification. Age prediction in this study used nine indicators of morphological changes, viz: ridges and furrows on the symphysial surface, ridge of pubic tubercle, lower extremity, ventral beveling, ossific nodules, dorsal margin, ventral rampart, general macroscopic changes of symphysial surface, and bone density of the symphysial surface. Samples were drawn from 262 male individuals. The study procedures are as follows: Firstly, we examined the morphological features of pubic symphysis using criteria similar to Hanihara's and Suchey-Brooks (SB). Secondly, we evaluated each stage with an appropriate score. Thirdly, we deduced four equations of male age assessment of morphological features by statistic analysis. The results were compared with Hanihara's and Suchey-Brooks method; the similarities and differences among them were discussed objectively. The method produced consistent results as well as developing the criteria of Hanihara's and Suchey-Brooks'.     

Personal Identification Using the Frontal Sinus*

Abstract: The frontal sinuses are known to be unique to each individual; however, no one has tested the independence of the frontal sinus traits to see if probability analysis through trait combination is a viable method of identifying an individual using the frontal sinuses. This research examines the feasibility of probability trait combination, based on criteria recommended in the literature, and examines two other methods of identification using the frontal sinuses: discrete trait combinations and superimposition pattern matching. This research finds that most sinus traits are dependent upon one another and thus cannot be used in probability combinations. When looking at traits that are independent, this research finds that metric methods are too fraught with potential errors to be useful. Discrete trait combinations do not have a high enough discriminating power to be useful. Only superimposition pattern matching is an effective method of identifying an individual using the frontal sinuses.

Stature Estimation from Foot Length Using Universal Regression Formula in a North Indian Population

Abstract:  Stature is a significant parameter in establishing identity of an unknown. Conventionally, researchers derive regression formula separately for males and females. Sex, however, may not always be determined accurately, particularly in dismembered remains and thus the need for a universal regression formula for stature estimation irrespective of sex of an individual. The study was carried out in an endogamous group of North India to compare the accuracy of sex-specific regression models for stature estimation from foot length with the models derived when the sex was presumed as unknown. The study reveals that regression equation derived for the latter can estimate stature with reasonable accuracy. Thus, stature can be estimated accurately from foot length by regression analysis even when sex remains unknown.
