Objective:
To explore the growth status of epiphysis of sternal end of clavicle using thin-section computed tomography (CT) and to study the relationship between the status and the chronological age of Sichuan Han nationality youth.
Methods:
According to the Schmeling's report and the age range of our samples, the ossification status of medial clavicle epiphysis was classified as four stages. CT films of 565 patients between 15 and 25 years were studied based on the classification and analyzed statistically.
Results:
There was no statistical difference between the sexes (P > 0.05). The calculated empiric distribution function showed that 100% of stage 1 patients were under 18 years, 75% of stage 2 patients were under 18 years, 94.5% of stage 3 patients were over 18 years, and 100% of the stage 4 patients were over 20 years, respectively.
Conclusion:
The ossification of medial epiphysis of the clavicle for those around 18 years has certain regular. These characteristics can be used for forensic identification of the skeletal age, especially 18 years, which is the criminal responsibility age.
