The paradox of internal fixation for treating fractures is that fixation is required to achieve union, while flexibility is necessary to restore normal mechanical properties of bone after union. Three series of experiments were performed to investigate the role of plate rigidity on fracture repair and changes in bone mass. Using plates with tenfold differences in axial and bending rigidities, the authors were able to show some advantages in fracture healing and bone remodelling with less rigid plates.
