title: [The analysis of variation of Han female adolescent bone development in Henan and Zhejiang province].
abstract: OBJECTIVE
  To study the difference of Han female adolescent bone development in Henan and Zhejiang province.
  
  
  METHODS
  All radiography including sternal end of clavicle and six main bone joints were taken from 599 female adolescents with age between 12 to 19 in Henan and Zhejiang province. Twenty four skeletal development indexes were analyzed based on "The Grading Standards" of skeletal growth of teenagers and then the bone age were calculated using mathematical model functions. The ratios of the bone age and the chronological age were analyzed by statistical software.
  
  
  RESULTS
  The development of Henan female adolescents' skeleton was about 0.39 years earlier than that in Zhejiang at the age of 14-15 years old. The development of Henan female adolescents' skeleton was about 0.37 years later than that in Zhejiang at the age of 15-16 years old. The development of Henan female adolescents' skeleton was about 0.38 years later than that in Zhejiang at the age of 18-19 years old. There was no statistics significance in other age group.
  
  
  CONCLUSIONS
  The female adolescent bone development in Henan province is faster at earlier stage and then slower than that in Zhejiang province. The results provide potential value for the forensic medicine, anthropology and clinical medicine.
