title: Nonunion of capital femoral physeal fracture with a large metaphyseal fragment.
abstract: This report presents a case demonstrating the nonunion of a capital femoral physeal fracture with a large metaphyseal fragment in a 10-year-old boy. To our knowledge, there is no previously reported case of this type of nonunion. The treatment of this nonunion presented a potential risk of premature physeal closure and avascular necrosis of the femoral head, so internal fixation using cannulated screws and percutaneously drilling with a Kirschner wire to the metaphyseal fragment was used and was effective in bone union without these complications.
