The steel nail used for femoral neck fracture can be removed or left inside the body for a long time. Under the current state of medical technology, the materials used for internal fixation of fractures are very biocompatible and will not affect the human body if they are left in the body for a long time. For patients with femoral neck fracture, after the femoral neck healing surgery, you can take out such internal fixation devices at an opportune time, so as to avoid false alarms when the patient passes through the security check. However, if the patient confirms to take out, it is recommended to try to take it out about six months after the fracture has healed. At this time it is easier to take out, if the time is too long it is not good to take out. If the time is too short, it may lead to insufficient local bone strength, and then produce corresponding damage. Clinically, for some patients with poor physical condition or contraindications to surgery, it is also possible not to remove this kind of steel nails.
