Definition of dynamisation

Dynamisation: The mechanical load transferred across a fracture locus can be increased, at a certain healing stage, in order to enhance bone formation, or to promote "maturation" of the healing tissues. An example would be the reduction in stiffness of an external fixation, either by loosening some clamps, reducing the number of pins, or moving the tubular construct further from the bone. Early dynamisation, i.e. before solid bridging of the bone, can result in stimulation of callus formation. The value of later dynamisation is debatable.
