A prospective, randomized study investigating the possible benefits of immediate mobilization and frequent physiotherapy following a wrist fracture treated by volar plating.

The current study will test the following null hypothesis:

There is no significant difference between patients who receive a cast for the first 2 weeks postoperatively and then instructions in home exercises and patients who receive a cast for 2-3 days postoperatively and then have frequent sessions with a physiotherapist following volar locked plating for a extraarticular distal radius fracture, as evaluated by self-reported satisfaction after 3 months.

The study will focus on patients treated with volar locked plating following an extraarticular distal radius fracture.

In a prospective manner the investigators intend to analyze hand function, x-ray and other parameters in order to investigate whether early mobilization and a targeted program of physiotherapy postoperatively leads to a better functional result and earlier return to a normal activity level. The investigators analysis will also focus on the safety of early mobilization with regards to possible detrimental effects on the osteosynthesis, bony union, associated soft-tissue injuries and functional outcome. The investigators also intend to assess the cost of more intensive follow-up and physiotherapy and do a cost-benefit evaluation.
