Abstract
Radiological assessment of ossification of medial clavicular epiphysis plays a vital part in age estimation of living adolescents and young adults. In the present study, skeletal maturity at the medial end of the clavicle for a known chronological age of the deceased of Tamilnadu population was analysed. Out of 155 clavicles that were collected from the autopsy samples, 117 belonged to male and 38 clavicles belonged to females. Based on radiological examination, ossification process was divided into 4 stages: stage I: Centre not appeared; stage II: Centre appeared but no union; stage III: Union started but incomplete; stage IV: Complete union. Majority of cases showed appearance of ossification centre at 17–18 years in females and 19–20 years in males. Earliest age of fusion was 20 years in females and 22 years in males. Majority of cases showed complete fusion at 25–26 years in both gender. No significant difference was observed in ossification activities in both sexes for the right and left clavicle.
