Factors predicting adverse outcome in complete intra-articular distal radius fractures

Purpose To determine risk factors associated with adverse functional and radiological outcome in complete intra-articular distal radius fractures (AO 23 C2-3) with a minimum follow-up of 1 year. Results PRWE scored a median of 4.5 points (range 0-72.5) after a median follow-up of 31 months (range 12-70 months). A concomitant polytrauma was associated with a worse PRWE (beta=23.34, p<0.01) and was also significantly associated with the use of a temporary external fixat- or (chi(2) = 11.93; p<0.01) and high-energy trauma (chi(2) = 19.39; p<0.01). Radiological outcome measures 1 year postoperative did not correlate with clinical outcome measures. Conclusion This cohort of complete intra-articular distal radius fractures (AO/OTA 23 C2-3) shows a good clinical outcome at medium-term follow-up independent of the radiological outcome. A concomitant polytrauma was associated with worse functional outcome and a higher complication rate. This is most likely due to the associated injury severity. These factors help the treating physician in decision-making and informing patients when treating displaced intra-articular radius fractures.
