Summary
Brief summary
Aim: Osteosynthesis with locking plate/screws has become increasingly popular in recent
years. It is the only treatment option which allows immediate postoperative immobilization.
However, compared to conservative treatment or treatment with external fixators, locking
plates are very expensive and the operation can be very challenging, even for experienced
surgeons. The long-term results of all treatment modalities are equal, which has been shown
in numerous studies. However, there are no evidence based studies published yet which look at
short-term outcomes. The investigators do feel but do not know that patients who do not need
postoperative immobilization return to work significantly earlier or are independent faster
than patients whose wrists are immobilized for up to 6 weeks. If that is the case, then the
higher costs and risks of the operation are justified, if not, then we have to re-evaluate
our indications for using locking distal radius plates distal radius Methods: Group 1:
Treatment of distal radius fractures with either volar or dorsal locking plates. No fixation
postoperatively, immediate ROM (range of motion) exercises and usage of the wrist in
activities of daily life (ADL) allowed.

Radiological and clinical controls 2 weeks, 6 weeks and 12 weeks postoperatively. Endpoints
are time to return to work / return to independency (in older people), ROM; Grip strength
(with Jamar Dynamometer).

Outcome scores are DASH (Disability of Arm, Shoulder and Hand Score)and PRWE (Patient related
wrist evaluation).

Group 2 Treatment of distal radius fractures with either an external fixator +/- K-wires or
with K-wires and forearm cast or by cast alone. Main issue is that the wrist is immobilized
for a period of 6 weeks. Radiological and clinical controls 2 weeks, 6 weeks and 12 weeks
postoperatively. Endpoints are time to return to work / return to independency (in older
people), ROM; Grip strength (with Jamar Dynamometer). Outcome scores are DASH and PRWE. Both
plating and external fixation / cast fixation are standard and accepted treatment modalities
for distal radius fractures. A power analysis indicated that a total sample size of 52
patients randomized equally (1:1) to each treatment arm without any blocking or
stratification would provide 80 % statistical power (alpha = .05, beta = .20) to detect a 20%
difference in mean DASH and PRWE scores.
