Steel nailing of the femoral head is more effective in younger people with non-displaced fractures and less effective in older people. Steel nailing after femoral neck fracture generally refers to hollow nail fixation. Femoral neck fracture is divided into three kinds of fracture under the head, the middle of the neck and the base of the fracture, the application of hollow nail fixation is more common, usually with three hollow nails fixation. Femoral head steel nailing is a method of treating femoral neck fracture. Hollow screws can be used for fixation after femoral neck fracture, and three to four finished screws are usually needed. People younger than middle-aged and younger have better results after fixation for nondisplaced fractures, and most are able to heal completely. If artificial joint replacement is performed, there is the disadvantage of needing multiple revisions due to the limited life span of the joint, which increases the patient’s pain. In the elderly, femoral neck fractures lose the ability to heal and generally do not heal after fixation with steel pins. Hip arthroplasty is recommended for elderly femoral neck fractures. Treatment of femoral neck fractures with nail fixation requires that the patient go to a hospital and be evaluated by a doctor for surgical treatment.
