Introduction
A repeated closed reduction (“re-reduction”) of a displaced distal radius fracture is a common procedure performed to obtain satisfactory alignment and avoid surgery when the initial reduction is deemed unsatisfactory. However, the efficacy of re-reduction is unclear. Compared to a single closed reduction, does a re-reduction of a displaced distal radius fracture: (1) improve radiographic alignment at the time of fracture union and, (2) decrease the rate of operative intervention?
Materials and methods
Retrospective cohort analysis of 99 adults aged 20–99 years with extra-articular or minimally displaced intra-articular, dorsally angulated, displaced distal radius fracture with or without an associated ulnar styloid fracture who underwent a re-reduction, compared against 99 adults matched for age and sex who were managed with a single reduction. Exclusion criteria were skeletal immaturity, fracture-dislocation and articular displacement greater than 2 mm. Outcome measures included radiographic alignment at fracture union and rate of surgical intervention.
Results
At 6–8 weeks follow-up, the single reduction group had greater radial height (p = 0.045, CI 0.04 to 3.57), and less ulnar variance (p < 0.001, CI − 3.08 to − 1.00) compared to the re-reduction group. Immediately following re-reduction, 49.5% of patients met radiographic non-operative criteria, but by 6–8 weeks follow-up, only 17.5% of patients continued to meet these criteria. Patients in the re-reduction group were treated with surgery 34.3% of the time, compared to 14.1% of the time for patients in the single reduction group (p = 0.001). In patients aged under 65 years, 49.0% of those who underwent a re-reduction were managed with surgery, compared to 21.0% of those who had a single reduction (p = 0.004).
Conclusion
A re-reduction performed to improve radiographic alignment and avoid surgical management in this subset of distal radius fractures had minimal value. Alternative treatment options should be considered before attempting a re-reduction.
