Abstract

This study reported the incidence of validated adult distal radius fractures in Oslo, Norway, in 2019. The incidence has been reduced over the last 20 years. However, it is still high compared to other regions in Norway and some of the other Nordic countries.

Purpose: We aimed to report the incidence of distal radius fractures in Oslo in 2019 and compare it to the incidence rates in 1998/1999.

Methods: Patients aged ≥ 20 years resident in Oslo sustaining a distal radius fracture in 2019 were identified by electronic diagnosis registers, patient protocols, and/or radiology registers. The diagnosis was verified using medical records and/or radiology descriptions. We used the same method as the previous study from Oslo, making the comparison over time more accurate. The age-adjusted incidence rates and the age-standardized incidence rate ratio (IRR) were calculated.

Results: The absolute number of fractures decreased from 1490 in 1998/1999 to 1395 in 2019. The IRR for women and men in the age group ≥ 20 years in 2019 compared to 1998/1999 was 0.77 (95% CI 0.71-0.84) and 0.77 (95% CI 0.66-0.90), respectively. The IRR for women and men in the age group ≥ 50 years in 2019 compared to 1998/1999 was 0.78 (95% CI 0.71-0.86) and 0.78 (95% CI 0.63-0.97), respectively. For the population in Oslo with Asian background compared to Norwegian background in the age group ≥ 50 years, the IRR in 2019 was 0.57 (95% CI 0.40-0.80) for women and 0.77 (95% CI 0.44-1.37) for men.

Conclusions: The incidence of distal radius fractures in Oslo has decreased over the last 20 years. It is still, however, higher than in other areas of Norway and in some of the other Nordic countries.
