There is no universally accepted definition of nonunion of a fracture. Generally, failure of a fracture to heal in 6-8 months constitutes a nonunion. The fracture repair process may be affected by mechanical or biological factors or a combination of both. The delayed union and nonunion are two different entities that differs on their physiophatology, outcome and treatment. Treatment must be tailored to the individual patient to address all components of the problem. Nonunions of long bones fractures can be treated successfully with one operative procedure in more than 90% of patients. In fact, 80% of patients can have good or excellent final restoration of mechanical axis alignment and proper length.(Rev Med Hered 2009;20:31-39)
