Abstract
In 4–6 months, most fractures will unite or at least show progressive healing on serial X-rays. If a fracture has not healed by that time, it is considered to be a delayed union. Even if the initial internal fixation had rendered the fracture lines well adapted and hardly visible, these fracture lines will become progressively wider and some cloudy, poorly delineated “irritation callus” may be present. Resorption areas around the internal fixation devices will show evidence of loosening and irritation.
