The purpose of this study is to examine whether operation and fixation with a metal plate gives better result from the patient's perspective than plaster treatment in elderly patients with a displaced wrist fracture.

We will perform a prospective randomized clinical trial comparing open reduction and internal fixation with a volar plate with closed reduction and plaster treatment in elderly patients with a displaced Colles' fracture in order to test the null hypothesis that the patient-perceived result is equal after conservative or operative treatment. Secondary outcomes are objective physical measurements.

Inclusion Criteria:

• Unilateral unstable dislocated dorsally angulated fracture of the distal radius (radial shortening ≥4 mm and/or dorsal angulation ≥20°).

Exclusion Criteria:

• Previous displaced fracture of the distal radius.
• Additional fractures of the upper extremities, an open fracture, terminal disease, patient not fit for surgery, unwilling or unable to co-operate with follow-up (advanced dementia (SPMSQ<5), psychiatric illness, alcohol abuse).
