Pediatric glenoid version changes significantly with age, becoming less retroverted from infancy to childhood. This study establishes crucial baseline data for normal glenoid version in children.

Area of Science:

  • Orthopedics
  • Pediatric Imaging
  • Anatomy

Background:

  • Glenoid version is a critical parameter in shoulder biomechanics and pathology.
  • Understanding pediatric glenoid version is essential for diagnosing and managing shoulder conditions in children.
  • Existing literature lacks comprehensive data on age-related changes in pediatric glenoid version.

Purpose of the Study:

  • To determine the normal range and age-related variations of glenoid version in a pediatric population.
  • To establish normative data for pediatric glenoid version using advanced imaging techniques.
  • To compare pediatric glenoid version with established adult values.

Main Methods:

  • Retrospective review of computed tomographic (CT) scans and magnetic resonance images (MRI) from 111 asymptomatic children.

Related Experiment Videos

  • Quantitative measurement of glenoid version on standardized imaging planes.
  • Statistical analysis to assess age-related differences and significance.
  • Main Results:

    • Glenoid version demonstrated significant retroversion in early childhood, averaging -6.3 +/- 6.5 degrees in the first two years of life.
    • By the end of the first decade, glenoid version approached adult values, averaging -1.7 +/- 6.4 degrees.
    • The observed age-related changes in glenoid version were statistically significant (p = 0.0013).

    Conclusions:

    • Pediatric glenoid version exhibits a developmental trend, transitioning from retroversion in infancy to a more neutral version in older children.
    • This study provides essential normative data for pediatric glenoid version, aiding in clinical assessment.
    • The findings support the need for age-specific reference ranges in the evaluation of pediatric shoulder abnormalities.
