Pediatric endocrinology

A Simplified Method for Assessing Bone Age in Adolescents

Clin Endocrinol (Oxf)Published Retrospective methodological study

Authors' conclusion

The simplified method offers a transparent, standardised, and reproducible approach to adolescent skeletal age assessment.

Study context

Population
Hand and wrist radiographs of adolescents referred for short stature but otherwise healthy; Greulich-Pyle (GP) bone age ≥9 years (girls) and ≥11 years (boys)
Participants
117 radiographs
Exposure
Simplified method vs Greulich-Pyle atlas
Outcome
Agreement of simplified method with GP (experienced raters)
Methodological detailsduplicate readings by experienced and inexperienced raters, Bone age scored independently in two rounds by two paediatric endocrinologists and, for the simplified method, two residents
  • Duplicate readings by experienced and inexperienced raters
  • Bone age scored independently in two rounds by two paediatric endocrinologists and, for the simplified method, two residents

Main finding

As reported in the abstract

Readings within ±1 year of GP

about 91%

Observational data: associations, not effects.

Further findings

Reliability coefficients for both methods
exceeded 0.9
Repeatability of simplified method slightly lower than GP but within clinically acceptable limits and close to predefined acceptability thresholds for inexperienced raters
