Summary

Rhizarthrosis (osteoarthritis of the thumb base) is linked to manual labor, particularly banknote processing. However, specific tasks like manual counting did not show a higher prevalence in this study.

Area of Science:

  • Occupational medicine
  • Rheumatology
  • Epidemiology

Background:

  • Rhizarthrosis, or osteoarthritis of the thumb base, affects 10-30% of individuals over 60.
  • Its classification as an occupational disease is debated due to conflicting study results on physical stress.
  • Previous research has yielded inconclusive findings regarding the link between occupational physical stress and rhizarthrosis.

Purpose of the Study:

  • To investigate the correlation between rhizarthrosis prevalence and manual banknote processing at the National Bank of Belgium (NBB).
  • To assess the impact of specific job roles within the NBB on the development of rhizarthrosis.

Main Methods:

  • A cohort of 195 National Bank of Belgium employees with manual or automated banknote processing roles was studied.

  • Detailed job histories were reconstructed to quantify exposure duration for specific roles.
  • Participants underwent clinical and radiological examinations to diagnose and score rhizarthrosis in both hands.

    • Main Results:

    • The overall prevalence of rhizarthrosis was 27% in women and 17% in men.
    • A significant increase in rhizarthrosis risk was observed after 10 years of full-time exposure (OR: 1.53).
    • The specific job of 'manual counting,' despite being perceived as strenuous, did not show a significantly higher prevalence of rhizarthrosis.

    Conclusions:

    • Rhizarthrosis is correlated with age, gender, and general manual labor, including banknote processing.
    • The study did not find a specific link between the 'manual counting' job and an increased prevalence of rhizarthrosis.
    • These findings contribute to understanding occupational risk factors for thumb base osteoarthritis.
