- Prospective collection of data on 4000 distal radial fractures collected at the Edinburgh Orthopaedic Trauma Unit
- Outcome measures included radiographic measurements at 1 week and 6 weeks
- Predictors of early and late instability were patient age, metaphyseal comminution, and ulnar variance.
- Minimally displaced fractures only had a 10% chance of later instability
- Displaced fractures had 43% chance of early instability and 47% chance of late instability
- Discussion: most important predictive factors were age of the patient, comminution, and position of fracture (displacement) at presentation
