Stature estimation of teenagers by limb long bones with computerized radiography / 法医学杂志

ABSTRACT

OBJECTIVE@#Relative parameters of upper limb bones, tibia and fibula were measured with computed radiography and used to establish the mathematical models for stature estimation of teenagers (from 14 to 18 years old) of Han population in Sichuan Province.@*METHODS@#The upper limb bones, tibia and fibula of 194 subjects were taken computerized radiography on normal position and were measured the lengths between relative landmarks. The body height of each subject was recorded. Linear regression equations for stature estimation between body height and the lengths of upper limb bones, tibia and fibula were established.@*RESULTS@#Forty-two single linear regression equations and 4 multiple regression equations were obtained. The coefficients of correlation(r) were 0.689-0.917 and the standard errors of estimate(SE) were between 3.075 and 5.485 cm. All of the equations were statistically tested and diagnosed with good applicability.@*CONCLUSION@#These equations could be used to estimate the body height of Sichuan Han population aged from 14 to 18. The lengths of the upper limb bones, tibia and fibula measured on the CR films could be useful to stature estimation of the adolescence and the forensic personal identification.
