Mechanical performance of the external fixation systemA computerized analysis of a mathematical model
Mechanical performance of an extemal fixator depends on many variables. Of these, diameters and lengths of the pins and rods which are used in the fixation system are important. A computerized analysis ofa mathematical model which was developed for a unilateral uniplanar external fixator was made for determining the effects of these variables on the mechanical performance of the system. It has been concluded that more rigid fixation could be obtained by using larger diameter and shorter pins and rods.
