Age of fusion of epiphysis at distal end of radius and ulna
Main Article Content
Abstract
BACKGROUND: Though the general development including height, weight, secondary sexual characteristics are helpful, eruption and maturity of teeth are quite reliable data for estimation of age, changes in bones specially time related appearance and fusion of different ossification centers in growing periods are valuable indices for assessing the age.
MATERIALS AND METHODS: The study was conducted in the Department of Forensic medicine and Toxicology at Govt. Medical College & New Civil Hospital, Surat during the year from April 2009 to March 2010 in 218 cases of 14 to 21 years by taking digital x-rays of lower end of radius and ulna.
RESULTS: In the study, we observed that fusion in the lower end of Radius started in the age group of 14-15yrs which is completed at 20 to 21 years, while fusion in the lower end of Ulna started in the age group of 14-15yrs which is completed at 19 to 21 years.
CONCLUSION: In the present study from the observations, conclusions were drawn that fusion of epiphysis of distal end of radius occurs at 21 years in male and at 20 years in female. The fusion of epiphysis of distal end of ulna occurs at 21 years in male and 19 years in female. Thus in female, the ossification centers of distal end of radius and ulna occurs earlier than males by one to three years.
