IntroductionThe incidence of distal radius fractures (DRFs) is reported, with conflicting results. To ensure evidence-based practice, the variation in treatment over time should be monitored. Treatment in the elderly population is particularly interesting because newer guidelines find little indication for surgery. Our primary aim was to assess the incidence and treatment of DRFs in the adult population. Secondly, we assessed the treatment stratified on non-elderly (aged 18-64 years) and elderly (aged 65+ years) patients.MethodsThis is a population-based register study comprising all adult patients (i.e. aged over 18 years) with DRFs in the Danish National Patient Register from 1997 to 2018. Data were extracted using the ICD-10 code for DRF (DS52.5), and the incidence was calculated using data from Statistics Denmark. We defined a case as surgically treated if a relevant procedure was performed within three weeks of the DRF diagnosis. Nordic procedure codes were used to define surgical treatments as either plate (KNCJ65), external fixation (KNCJ25), k-wire (KNCJ45), or 'other' (KNCJ35,55,75,85,95).ResultsA total of 276,145 fractures were included, with an overall increase in DRFs of 31% during the study period. The overall incidence was 228/100,000/year, which increased by 20% during the study period. The increased incidence was especially notable among women and those aged 50-69 years. Surgical treatment steadily increased from 8% in 1997 to 22% in 2010, thereafter reaching a plateau at 24% in 2018. The surgical rate in the elderly group was as high as in the non-elderly group. In 1997, the treatment distribution of DRFs was as follows: 59% external fixation, 20% plate fixation, and 18% k-wire fixation. From 2007 and onwards, plating was the primary choice of surgery, and in 2018, 96% of patients were treated with a plate.ConclusionWe found a 31% increase in DRFs over a 22-year period, mostly driven by an increase in the size of the elderly population. The surgical rate increased markedly even in the elderly group. There is a lack of evidence on how beneficial surgery is for elderly patients, and similar surgical rate between the elderly and non-elderly calls for hospitals to re-evaluate their treatment strategies.Copyright © 2023.
