The treatment of impacted distal radius fractures is complex. Internal fixation by a dorsal approach with arthrotomy should be considered, particularly when the fractures are dorsally comminuted. This was a retrospective, observational study of 26 patients operated between 2008 and 2012 who were reviewed in September 2013. In the surgical procedure, a single dorsal incision was made over the distal radius and arthrotomy performed; the fracture site was stabilized with two 2.4mm locking plates. The average follow-up was 39months. All fractures were type 23C in the AO classification. All patients were assessed with the QuickDASH and Mayo Wrist scores. Total range of motion was 82% of the contralateral side. Grip strength was 30kg in average. The mean radial sagittal tilt was +6° postoperatively. No plate movement or intra-articular screws were present. Four patients developed symptomatic early osteoarthritis. Thirteen patients had the plate removed due to discomfort. No tendon ruptures were observed. The dorsal approach remains a treatment option for specific intra-articular fractures. It offers direct intra-articular congruency control, along with a stable buttress and locking fixation for early mobilization. Our results are comparable to those using other surgical techniques for this type of high-energy fracture.
