Fracture Management
A registrar is reviewing the principles of fracture fixation before an upcoming FRACS Part I examination. The consultant asks about the biomechanical principles underlying different fixation strategies and when each should be applied. The discussion covers compression plating, bridge plating, locked plating, and intramedullary nailing. Regarding fracture fixation principles:
