Summary

The Risser sign is not a reliable measure of skeletal maturity or scoliosis progression compared to chronological age. Hand and wrist radiographs are more accurate for assessing skeletal age in orthopedic practice.

Area of Science:

  • Orthopedics
  • Radiology
  • Biostatistics

Background:

  • The Risser sign is a widely used radiographic method for assessing skeletal maturity in pediatric patients.
  • Accurate skeletal maturity assessment is crucial for orthopedic treatment planning, particularly for scoliosis.

Purpose of the Study:

  • To critically evaluate the statistical accuracy of the Risser sign in predicting skeletal maturity and scoliosis progression.
  • To compare the predictive accuracy of the Risser sign with chronological age and hand/wrist radiographs.

Main Methods:

  • Statistical analysis of existing orthopedic literature on the Risser sign.
  • Comparative analysis of Risser sign accuracy against chronological age and radiographic skeletal age determination.

Main Results:

  • The Risser sign's accuracy in estimating skeletal maturity is statistically questionable.
  • Chronological age is a more reliable predictor of skeletal age than the Risser sign.
  • The Risser sign does not offer superior prediction of scoliosis progression compared to chronological age.

Conclusions:

  • The Risser sign should not be routinely substituted for hand and wrist radiographs for skeletal age assessment.
  • Chronological age is a more dependable metric for predicting skeletal maturity and scoliosis progression in orthopedic contexts.
