External validation and revision of the Lafontaine criteria for unstable distal radius fractures: a retrospective study

The performance of the Lafontaine criteria in discriminating unstable distal radius fractures was unacceptable in our study cohort. The updated criteria using age group (< 56 years, 56-74 years, and > 74 years), associated ulnar fractures, and initial radial shortening > 3 mm was found to have moderate discrimination; however, further research is warranted to improve the prediction and measurement reliability of fracture instability.
