Osteofibrous dysplasia and fracture callus can be difficult to differentiate, but the history and location should help, and they typically have prominent osteoblastic rimming around the bone trabeculae.
A basic investigation of LIPUS in fracture healing showed that LIPUS increased the strength of the fracture callus and aggrecan gene expression in a rat fracture model and initiated bone healing in a rat fracture nonunion model (Takikawa et al.
Available studies suggest a narrow window for fixation exists; 7 to 14 days are often required for diminution of swelling, and after 3 weeks, wound closure and fracture callus can be problematic.
There may be bands of fibrous tissue that have no giant cells present or osteoid foci within a fracture callus.
