Conditions

distal radius fracture fracture of forearm bone

Interventions

In one group the fracture will be initially immobilized with circumferential below-elbow cast, and in the other group the fracture will be initially immobilized with below-elbow splint.

Sponsors

Erasmus MC, Universitair Medisch Centrum Rotterdam
Lead Sponsor

Eligibility

Age
18 Years to 99 Years

Inclusion criteria

Inclusion criteria: In order to be eligible to participate in this study, a subject must meet all of the following criteria: 18 year or older, with a primary displaced fracture of the distal radius which is treated conservatively after closed reduction, and who are willing to comply with the study protocol.

Exclusion criteria

Exclusion criteria: A potential subject who meets any of the following criteria will be excluded from participation in this study: failure to reach proper fracture alignment (5) after reduction(s) in the emergency room, inability to complete study forms due to any mental status or insufficient command of the Dutch language, both-bone forearm fracture (styloid ulnae fracture excluded), concomitant injuries to ipsilateral extremity or multi-traumata.

Design outcomes

Primary

MeasureTime frame
Difference between groups in proportion of fracture re-displacement of the initial reduced distal radius fracture. Besides, differences in medical consumption, absence from work or decreased productivity, and patient costs, will be assessed.

Secondary

MeasureTime frame
- pain medication use - surgical interventions - physical examination of range of motion of the arm and grip strength - recovery of functioning: QUICK-DASH and PRWE questionnaires - change in pain severity: number rating scale (NRS) for pain - general quality of life: EQ-5D-5L - total costs: intramural and extramural medical costs (iMCQ) and productivity loss (iPCQ) - adverse events.
