Only Lafontaine's definition originated from a clinical study, describing a retrospective cohort of 167 cases.s- Lafontaine et al performed a univariate analysis for each risk factor and found a significant influence of each factor on the radiological outcome. They concluded that only patients with three or fewer instability factors had a satisfactory radiological outcome. Accordingly, Lafontaine considered a distal radius fracture unstable if three or more of the following factors were present: dorsal angulation exceeding 20°; dorsal comminution; intra-articular radiocarpal fracture; associated ulnar fracture; and
