It is unlikely that the removal of a nail for a fracture of the neck of the femur will result in necrosis of the femoral head. Fractures of the femoral neck cause disruption of the blood supply to the femoral head, which may result in ischemic necrosis of the femoral head, and are not caused by the removal of the titanium nail for internal fixation. In femoral neck fracture, titanium alloy nails are inserted for internal fixation at the time of treatment, which is used to maintain the stability of the hip joint. More than one year after surgery, the fracture is fully recovered, and the internal fixation can be removed by a second surgery, which usually does not increase the risk of femoral head necrosis. In addition, the titanium alloy nails used in the clinic nowadays are very biocompatible, basically will not have rejection reaction with the organism, and some of them can not be removed due to poor physical condition, advanced age and other factors.
