Brief summary

Distal radius fracture (DRF) is a common fracture of which the incidence appears to be increasing worldwide. On average, a total of 17% of all diagnosed fractures are DRF's. In the Dutch guideline for DRF the treatment advice for DRF, without reduction, is treatment with plaster cast or brace for one-three weeks. Despite the advice in the guideline and despite several studies from the 90's showing that plaster cast treatment of a stable DRF for one week is safe, the usual length of plaster cast treatment for stable DRF is four-six weeks. In addition, recent studies have also shown that a long period of immobilization can lead to more post traumatic pain by increasing disuse and kinesiophobia. This evidence suggests that the usual duration (4-6 weeks) of plaster cast treatment for DRF is unnecessary. The aim of this feasibility study is to define whether one week of plaster cast treatment is possible and can lead to better functional results, with at least the same patient satisfaction and complications. In addition, this feasibility study will be used to define the sample size of the future RCT.

Secondary

MeasureTime frameDescription
Change in disability of the Arm, Shoulder and Hand (DASH) questionnaire scoreWeek 6, month 3, month 6 and month 12In addition to the PRWE questionnaire.
Change in Short-Form 36 questionnaire scoreWeek 6, month 3, month 6 and month 12In addition to the PRWE questionnaire.
ComplicationsDuration of study (12 months)The number of participants who experienced treatment related complications scored with a checklist.
Pain after DRFBaseline, week 6, month 3, month 6, month 12Pain will be assessed by a visual analog scale (VAS). Participants rate their pain level in a scale from 0 to 10; 0 representing no pain and 10 representing the worst pain imaginable.
