【摘要】： 目的制定中國漢族男性青少年骨發(fā)育分級標(biāo)準(zhǔn)圖譜及骨齡推斷方法。 方法于華南、華中及華東三地共攝取1059名11～20周歲男性漢族青少年鎖骨胸骨端及六大關(guān)節(jié)X線片,根據(jù)鎖骨胸骨端繼發(fā)骨化中心出現(xiàn)、六大關(guān)節(jié)干～骺閉合的時間確定骨化中心出現(xiàn)及骨骺閉合與年齡之間的關(guān)系;通過對骨化中心出現(xiàn)及骨骺閉合程度(分級)的分析制定當(dāng)代中國男性青少年骨齡鑒定標(biāo)準(zhǔn)圖譜;通過對骨化中心出現(xiàn)及骨骺閉合程度與年齡之間的相關(guān)性分析建立推斷骨齡的數(shù)學(xué)模型。 結(jié)果獲得了中國當(dāng)代男性青少年鎖骨胸骨端繼發(fā)骨化中心出現(xiàn)、六大關(guān)節(jié)干-骺閉合的確切年齡;制定了骨齡鑒定的標(biāo)準(zhǔn)圖譜;建立骨齡鑒定的數(shù)學(xué)模型(y=7.673+0.355*X1+0.128*X2+0.131*X3+0.082*X4+0.145*X6+0.084*X9+0.221*X15)等。回代檢驗顯示,當(dāng)誤差小于±1歲時,多元回歸方程鑒定年齡的準(zhǔn)確率為70.59%;當(dāng)誤差小于±1.5歲,其準(zhǔn)確率為88.24%。 結(jié)論中國當(dāng)代男性青少年鎖骨胸骨端繼發(fā)骨化中心出現(xiàn)、六大關(guān)節(jié)干-骺閉合時間、骨齡鑒定標(biāo)準(zhǔn)圖譜及骨齡鑒定數(shù)學(xué)模型可應(yīng)用于法醫(yī)學(xué)鑒定實踐,并可有效的提高骨齡推斷的科學(xué)性。
[Abstract]:Objective to establish the standard map of bone development classification and bone age estimation for male adolescents of Han nationality in China. Methods A total of 1059 male adolescents aged 11 to 20 years old in South China, Central China and East China received X-ray films of the sternum end of the clavicle and six major joints, according to the secondary ossification center of the sternal end of the clavicle. The time between metaphyseal closure and metaphyseal closure of six major joints was used to determine the occurrence of ossification center and the relationship between epiphyseal closure and age, and the standard map of bone age identification of contemporary Chinese male adolescents was established by analyzing the occurrence of ossification center and the degree of epiphyseal closure (grading). A mathematical model for estimating bone age was established by analyzing the correlation between the occurrence of ossification center and the degree of epiphyseal closure and age. Results the exact age of secondary ossification center at the sternal end of clavicle and the age of metaphyseal closure of the six major joints were obtained, the standard map of bone age identification was established, and the mathematical model of bone age identification was established (YJ7.673 0.355X 1 0.128X 1 0.128X 3 0.082X 4 0.145X 6 0.084 X 9 0.221 X 15). When the error is less than 鹵1 years old, the accuracy of multivariate regression equation is 70.59 and 88.24 when the error is less than 鹵1.5 years old. Conclusion the secondary ossification center at the sternal end of clavicle appears in contemporary Chinese male adolescents. The time of metaphyseal closure of six major joints, the standard map of bone age identification and the mathematical model of bone age identification can be used in forensic practice. And can effectively improve the scientific nature of bone age inference.
