External fixation can be applied using either modular or uniplanar techniques. The modular frames have the advantage of being more versatile, avoiding the complex wounds that are often seen.
The disadvantage of a modular frame is, that it is less rigid than the uniplanar fixator because of its multiple connections.
Pin placement outside of the anticipated zone of the definitive implant is a consideration, although not always possible. Reduce the fracture as well as possible, to avoid soft-tissue tension.
