About

The femoral neck fracture is the most prevalent injuries which commonly encountered among older people with high mortality, morbidity and young fit healthy ones who subjected to high-energy trauma . Non-union or avascular necrosis of femoral neck fracture which lead to loss of labor capacity and death, is the most commonly occurred complication and results in considerable burden for family. The treatment is difficult and challenging, and to minimize the negative results such as limited mobilization or other complications, it is essential to take active prevention and appropriate treatment depending on fracture pattern and patients' characteristics as early as possible. However, current implant selections for femoral neck fractures remain a topic of greater interest and controversy, and vary substantially from each other .

Full description

The incidence of femoral neck fracture accounts for 3.6% of all fractures, is the most prevalent injuries which commonly encountered among older people with high mortality, morbidity and young fit healthy ones who subjected to high-energy trauma . Non-union or avascular necrosis of femoral neck fracture which lead to loss of labor capacity and death, is the most commonly occurred complication and results in considerable burden for family. The treatment is difficult and challenging, and to minimize the negative results such as limited mobilization or other complications, it is essential to take active prevention and appropriate treatment depending on fracture pattern and patients' characteristics as early as possible. However, current implant selections for femoral neck fractures remain a topic of greater interest and controversy, and vary substantially from each other depending on the extent of displacement, fracture configuration, physiological age of the patient, bone quality or other relative factors. Nonoperative management is considered only when patients are seriously ill or presented with excessive surgical risk.
