The Significance of Posterior Cortex in Complicated Femoral Neck Fractures which were Internal Fixated

Purpose : When a surgeon carries out an operative treatment on a patient who has fractures of the femoral neck, he decides to do either the internal fixation for bony union or the aggressive treatment according to his experience and preparation, not according to the objective standard. The aim of this retrospective study is to prepare a guideline for the operative method. Materials and Methods : We analyse possible factors of the patient who has nonunion, avascular necrosis and loss of fixation after doing internal fixation in femoral neck fractures Results : In this treated case of femoral neck, the appearance of complications are influenced by the maintenance of internal fixation, shape of fractures, osteoporosis, and the position of fixations; but in the complicated cases without the loss of fixation, the shape of fractures always have posterior cortical communition. Conclusion : When we choose between simple fixation and aggressive treatments in cases of fractures of the femoral neck, we must treat according to the patient ’ s condition, displacement of the fracture, operative technique and existence of a posterior cortical comminuted fracture.
