Plates and intramedullary nails provide fracture stability through different biomechanical principles. Plates may function as compression, neutralisation, buttress, bridge or tension-band devices, while nails usually provide central load-sharing fixation. Absolute stability promotes primary bone healing, whereas relative stability permits controlled motion and secondary healing with callus formation. Construct behaviour depends on factors such as implant position, working length, screw configuration, fracture gap, bone quality and load sharing. Successful fixation requires a balance between mechanical stability and preservation of fracture biology.
