“…These differences do not seem to be due to sampling problems since the young age classes have similar sample sizes. Indeed, inter-population differences in the timing of bone fusion are widely documented for various skeletal regions (Stewart, 1979;Ubelaker, 1989;Terazawa et al, 1994;Banerjee and Agarwal, 1998;Schaefer and Black, 2005).…”

A new standardized scoring method was used to study age variation of the degree of fusion of the ventral face of the sacral vertebral bodies (SVF) in 904 adult skeletons of both sexes from two identified modern samples (20th c.): Frassetto collections (Museum of Anthropology, University of Bologna, Italy) and Colecção de Esqueletos Identificados (Museum of Anthropology, University of Coimbra, Portugal). SVF was scored for each fusion site (between S1 and S2, etc.) on a four-stage scale, from nonfusion (Degree 0) to complete fusion (Degree 3). Inter-observer error of 1.2% suggested good reproducibility. The data were analyzed according to age, sex, and population. There were sex and population differences only in young adults (20-34 years). Sex differences in SVF were present in both collections, with females displaying earlier fusion than males. The differences occurred until 35 years, after which there was a generalized prevalence of completely fused sacra. Population differences were observed for males, with the Sassari men showing later sacral vertebral fusion than the Coimbra men. Our study suggests that incompletely fused sacra can help in distinguishing young adults from old adults regardless of sex and population.

“…[5] Reports have shown that the study of epiphyseal union of bones is considered as a reasonable scientific and acceptable method for age determination by the law courts all over the world. [9,29] The fundamental basis of age estimation techniques in young people is based on the fact that the skeleton is constantly changing in small increments until the adult state is reached. [30] Previous authors described mainly two stages of union: non-union or completed union.…”

“…According to previous studies, differences exist in the timing of epiphyseal union between individuals from different populations. [9,10] Eveleth and Tanner [11] attribute the differences to population variability, climate, nutrition, secular change in growth or to simply lack of standardized methodology. In other parts of the world, the hand-wrist region has received the greatest attention in assessment of skeletal maturation compared to other areas.…”

Objectives: Age determination is needed in administration of justice, employment, marriage, forensic investigation and identification. This cross-sectional study aimed to investigate the relationship between stages of epiphyseal union at the knee joint and chronological age. Methods:Anterior posterior and lateral knee radiographs of 100 males and 110 females aged 9-19 years were examined. Epiphyseal union was divided into five specific stages in the femur, tibia and fibula. Fusion was scored as stage 0: non-union, stage 1: beginning union, stage 2: active union, stage 3: recent union, and stage 4: complete union. Results:Mean age gradually increased with each stage of union and varied between males and females. A statistically significant difference in mean age was recorded between stages for the three epiphyses. Epiphyseal union occurred earlier in females than in males. A statistically significant difference was observed between the mean age of union for males and females for stages 1 and 2 for the femur, and stages 0, 1, 2 and 3 for the tibia and fibula. Conclusion:The results of this study indicate that radiographic analysis of the knee is a valuable alternative for estimation of chronological age.

N. Yafl tayini uygulamalar›nda epifiz pla¤› kapanma derecelerinin incelenmesi.Adli T›p Bülteni, 2005;10(3):84-89. Adli T›p uygulamalar›nda yafl tayini önemli bir yer tutmaktad›r. Ülkemizde, kiflilerin nüfus kay›tlar› düzenli olarak tutulmad›¤›ndan, baz› hukuki durumlarda flah›slar›n gerçek yafllar›-n›n tespiti gerekmektedir. Bu konuda en s›k kullan›lan yön-tem, belirli yafl gruplar›nda belirli bölgelerin grafilerinin çekile-rek epifiz plaklar›n›n kapanma derecelerini saptamak ve flahs›n yafl›n› belirlemektir. Bu amaçla, Greulich-Pyle ve Tanner-Whitehouse Atlaslar› kullan›lmaktad›r. Ülkemizde, uygulama kolayl›¤› bak›m›ndan en çok tercih edilen yöntem Greulich-Pyle yöntemidir.Son zamanlarda yap›lan araflt›rmalarda, günümüz çocuklar›-n›n büyüme temposunun artt›¤› ve olgunlaflman›n daha erken oldu¤u bilinmektedir. Bizim çal›flmam›zda, halen kullan›lan yöntemlerin uyumlulu¤unun test edilmesi amac›yla, de¤iflik yafl gruplar›ndan çekilen 570 adet grafi incelenmifltir. Buna gö-re, el bile¤i, omuz ve pelvis grafilerinde 16 yafltan itibaren kapanmalar›n bafllad›¤›; gerçek yafl› 17 olan olgular›n el bile¤i grafilerinin %100'ünde, omuz ve pelvis grafilerinin %81.8'inde epifizlerin tam olarak kapand›¤› görülmüfltür. Sonuç olarak; halen uygulanmakta olan yöntemlerle, kronolojik yafl, kemik yafl›n›n çok gerisinde kalmaktad›r. Bunun için, nüfus kay›tlar› kesin olarak do¤rulanan sa¤l›kl› bireylerin grafileri üzerinde incelemeler yaparak toplumumuza özgü standart de¤erlerin oluflturulmas› gerekmektedir.Anahtar kelimeler: El bile¤i, epifiz, omuz, pelvis, yafl tayini.Age assessment has an important place in Forensic Medicine. Estimation of the accurate age is required in some legal processes as demographic records are not properly performed in Turkey. Age determination by researching the epiphyseal union of some specific joints in the specific age groups is the commonly used method. Most commonly used methods are GreulichPyle and Tanner-Whitehouse methods for this purpose Greulich-Pyle method is preferred in our country usually because of easy applicability.According to some recent studies, the rate of growth and development is quicker and so the maturation occurs earlier. In our study, 570 x-rays of different ages are evaluated to test the correlation of recent methods. We found that the epiphyseal union started at the age of 16, in hand-wrist, shoulder and pelvis. At the age of 17, the epiphyseal union was completed in 100% of the hand-wrist x-ray and 81.8% of the shoulder and pelvis roentgenograms.As a result, bone age is advanced in comparison with the chronological age by using recent methods. Standard data for domestic population must be collected by means of the x-rays of healthy people having regular demographic records and new standards should be established to prevent misinterpretation of the cases.
