title: Subtrochanteric nonunion of the femur.
abstract: Nonunion of the subtrochanteric region is usually secondary to incorrect surgical treatment. The main cause of failed osteosynthesis is related to interruption of the medial cortex of the femur. Either a closed method, with intramedullary nailing, or an open method, using cortical osteosynthesis and opposing bone graft, may be used to treat the pathology. Surgery differs depending on the instrumentation used for the initial treatment of the fracture. A total of 8 cases of intra- and subtrochanteric nonunion with intramedullary nailing and cortical osteosynthesis are reported.
