A biomechanical comparison of four fixed-angle dorsal plates in a finite element model of dorsally-unstable radius fracture

There was no significant difference between 2-part (AO/ASIF type 23-A3) and 3-part (AO/ASIF 23-C2) fracture models. Maximal stresses in the plates appeared above the fracture gap; therefore, it is worth considering the development of plates without screw holes above the gap.
