Distal radius fractures are treated surgically if severely displaced. This study aims to investigate the outcome after surgery. The investigators will randomize patients to either external fixation with optional addition of k-wires or open reduction and fixation with a volar plate.

Primary Outcome Measures:
  • The primary outcome is measured by DASH (Disability of the Arm, Shoulder and Hand), which is a self administered questionnaire validated for disease and dysfunction of the upper limb. [ Time Frame: 12 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • A secondary outcome measure is the degree of malalignment on the x-ray of the injured wrist. [ Time Frame: 12 months ] [ Designated as safety issue: No ]
  • A secondary outcome measure for this study is the EQ5D, a validated quality-of-life instrument. [ Time Frame: 12 months ] [ Designated as safety issue: No ]
