Trunk asymmetries in a Belgian school population

M Vercauteren, M Van Beneden, R Verplaetse

    Summary

    Clinically evident trunk asymmetries are common in schoolchildren, often presenting as rib humps or lumbar prominence. These findings are important for scoliosis screenings and appear to be physiological within certain limits.

    Area of Science:

    • Orthopedics
    • Pediatric Health
    • Biomechanical Assessment

    Background:

    • Trunk asymmetries are frequently observed in the general population.
    • Early detection of spinal deformities like scoliosis is crucial for effective management.
    • Understanding the prevalence and characteristics of trunk asymmetries in children is essential for screening protocols.

    Purpose of the Study:

    • To investigate the prevalence and characteristics of trunk asymmetries in a cohort of schoolchildren.
    • To determine the association between trunk asymmetries and measurable indicators such as rib hump and lumbar prominence.
    • To establish physiological limits for trunk asymmetry measurements in a pediatric population.

    Main Methods:

    • Screening of 270 schoolchildren from Belgian town schools for trunk asymmetries.

  • Clinical assessment of shoulder height, scapular position, iliac crest height, and waist triangle depth.
  • Measurement of rib hump and lumbar prominence using established methods.

    • Main Results:

    • A high prevalence of clinically evident trunk asymmetries was confirmed.
    • The majority of asymmetries were associated with measurable rib humps and/or lumbar prominence.
    • Age and sex did not significantly influence the degree or laterality of asymmetry.
    • Specific measurement thresholds (shoulder/iliac crest height ≤1 cm, waist triangle depth ≤1.5 cm, rib hump ≤8 mm, lumbar prominence ≤5 mm) were identified as physiological.
    • Rib humps were predominantly on the right, particularly in prepubertal girls.

    Conclusions:

    • Clinically evident trunk asymmetries are common in schoolchildren and frequently accompanied by rib humps and lumbar prominence.
    • Established measurement thresholds suggest a physiological range for these asymmetries.
    • The findings support the inclusion of rib hump and lumbar prominence assessment in scoliosis screenings for children.
