What is the Bone Age Test?

The Bone Age Test (or skeletal age assessment) is a medical procedure used to estimate a person's biological age based on the maturity of their bones, usually through X-rays of the left hand, wrist, and fingers.

  • It compares bone development to standard growth charts (e.g., Greulich and Pyle Atlas or Tanner-Whitehouse method).

  • Common in forensic, legal, and medical contexts—especially when birth records are unavailable or disputed.

Reliability±1 to 2 years (varies with nutrition, ethnicity, socio-economic factors)


Mains Perspective (GS Paper 2 & 3)

 Legal and Ethical Issues

  • Used in Juvenile Justice Act (JJA), 2015 cases to determine if an accused is a minor or adult.

  • However, courts have noted its inexact nature, making it a secondary evidence.

  • Example: Jarnail Singh vs State of Haryana (2013) – Supreme Court ruled medical tests including bone age should be used only if documentary proof is absent.

 Application in Sports & Identity

  • Used in age-fraud detection in sports (e.g., under-17 cricket/football).

  • Can be misused or produce incorrect results due to nutrition, genetics, and socioeconomic status.

Forensic and Medical Relevance

  • Helps in identifying unknown dead bodies, assessing growth disorders, or in cases involving child trafficking.

  • Important in public health programmes involving children’s growth and development.


Limitations & Challenges

  • Accuracy affected by:

    • Nutrition

    • Chronic illness

    • Ethnic variation

    • Socio-economic differences

  • Not definitive: Courts rely more on school records, Aadhaar, or birth certificates.

  • Bone age ≠ chronological age: biological maturity may differ by ±2 years.
