[Fracture of a transfixed intramedullary nail in a patient with pseudoarthrosis of the femoral diaphysis].

This is a case report on a patient with a multiple femur's fracture where a transfixed intramedullar nailing of Grosse-Kempf type has been done. "The nail dynamization" was not carried out before the beginning of vertical loading. Seven months after the full vertical loading had begun, at a sudden torsian movement of the extremity, the nail had broken. Analyzing the cause of the fixative material fracture, a conclusion has been made that, apart from the presence of adequate trauma, the nail fracture happened also due to the development of pseudoarthrosis of femur and the unfulfilled "nail dynamization".
