Age Assessment in the Living Lucina Hackman
2
Rationale Medical: Pinpoint timing of medical interventions Understand disease progression Assess efficacy of medical interventions Legal: Assess age of perpetrator/victim Assess age of asylum seekers
3
UNICEF estimates that around 50 million children are not registered at birth-no record of age. In the UK in 2007-3,525 unaccompanied children tried to enter the country- 54% resulted in age disputes Child trafficking (UK) is a growing issue- 76% of children trafficked fall into the 14- 17 age group (2009) Asylum
4
Current Practices Use of : 1.Psychological assessment 2.External physical assessment (secondary sexual characteristics) 3.Radiographs compare skeletal maturation (ossification centres and epiphyseal fusion times) with chronological maturation (Atlases)
5
Ossification centres Matches maturation of various parts of the skeleton with chronological age Appearance of ossification centres Changes in shape of ossification centres Fusion of ossification centres Use of growth-changes in size of skeletal elements
6
Challenges Are the atlases still relevant today? 1. Nutrition-secular changes 2. Population differences Is any atlas more accurate than another (in relation to each other or in relation to a modern population) If there is an error-where does it lie and in what direction
7
Current Project Access radiographs in Ninewells Hospital (numbers around 600 images for each joint area)-this is currently being undertaken Access equivalent dataset in New Delhi, India-August 2009 Compare results 1.Between Atlases 2. Between populations
8
Data Collection Examine each area of joint Compare how closely each area corresponds to the image shown for that age in the atlas Record the discrepancy Subject to statistical analysis
