Deformity correction (upper or lower extremities) can be done gradually or acutely. Gradual correction is done using a technique called distraction osteogenesis (distracting the bone). Gradual correction is usually done with external fixation and is more accurately performed using a 6 axis computer assisted fixator such as the ”TSF” or ”Taylor Spatial Frame”.
Acute correction can be performed depending on the degree of deformity and the status of the surrounding soft tissues. Acute correction is done more precisely by using external fixator-assisted techniques but the final result only has internal fixation (plate and screws or nail).
