Abstract
BACKGROUND: Fractures of the distal radius are the most common fractures of the upper extremity. The choice of surgical method has been debated and studies show that short-term differences, in favour of volar locking plates, are indistinguishable at 1 year follow-up. Few studies have investigated long-term outcomes beyond one year. The aim of this study was to investigate long-term (6-10 years) patient-reported outcomes after distal radius fracture surgery, and to determine how fracture pattern/complexity (Buttazzoni fracture type) affects the results. METHODS: 303 patients surgically treated for a distal radius fracture, from 2012-2016 were included. The questionnaires used were PRWE, Quick-DASH and EQ-5D. Previous studies have shown that fracture type influences the choice of surgical method and therefore fracture type was adjusted for in the statistical analysis. RESULTS: We found that patients treated with K-wires had significantly better Quick-DASH scores (p <0.05) and a lower degree of pain (PRWE pain scale) (p <0.05) than patients treated with volar locking plates. There was no difference between the two groups regarding the remaining outcome measures for any Buttazzoni type of fracture. CONCLUSION: On the basis of these results, K-wires can be considered an equivalent option to locking plates because of equal or better long-term outcomes, lower costs, and shorter operation times.
