Determining Age using Bones

Explore the science behind determining age using bone characteristics like the number, condition, and growth plates. Discover how X-rays can reveal age-related changes and identify key milestones in bone development, such as epiphyseal fusion and pelvic ossification. Learn about different bones' growth patterns and fusions, and understand what to look for in young and old individuals to estimate age accurately.

  1. Determining Age using Bones

  2. How bones show AGE • # of bones (adults have fewer) • Condition • Growth plate vs epiphyseal line

  3. Epiphysis – end of long bone • Epiphysis line-growth plate • Fused – bones joined together

  4. Sutures • Sagittal-open less than 35 yrs • Lambdoidal-starts at 21-closes at 30 yrs • Coronal-closed at 50 yrs

  5. X-ray of Bone Growth • https://www.youtube.com/watch?v=Plvd7eslg-Q • http://www.youtube.com/watch?v=0dV1Bwe2v6c

  6. What to Look For? • If the person is young: *Length of the bones (height) *Growth plate (epiphyseal line) Different bones fused at different times in our lives *Status of the teeth

  7. Young or Old?

  8. What to Look For? • In people over 20: • Epiphysis on sternal end of clavicle is last epiphysis to fuse at approximately 30 years

  9. What to Look For? • Over 30: • Look for deterioration • Less dense bones • More porous bones Normal X-ray Osteoporosis X-ray

  10. Best Bone for Age? • The pelvis!

  11. Ischium and Pubis • Ischium and pubis are almost completely united (7-8 years)

  12. Ileum, Ischium and Pubis • Ileum, ischium and pubis are joined together (13-14 years) • Ileum, ischium and pubis fully ossified (no epiphyseal unions) (20-25 years)

  13. Sacrum • Two lowest segments of sacral vertebrae are joined together (18 years) • All segments of sacrum are united (25-30 years)

  14. Back View of Sacrum

  15. Head and Tuberosities • Head and tuberosities are more defined at birth and join to become one epiphysis (6 years)

  16. Condyles • Radial head, trochlea and external condyle blend to unite with shaft (16-17) • Internal condyle unites with shaft (18)

  17. Upper Epiphysis • Upper epiphysis unites with shaft (20)

  18. Changes in Femur • Parts of the Femur

  19. Trochanters • Greater trochanter appears at age 4 • Lesser trochanter appears at ages13-14 • Head, greater and lesser trochanters join the shaft at age 18
