Historically, the definition of delayed union and nonunion have been based on time from the onset of injury. More recently, the exact time frames have been considered to be less important. Fracture healing is a dynamic progressive process, with intervention indicated for 3-5 months following injury if three consecutive monthly radiographic studies do not demonstrate progression of fracture healing [1].
