Titanium nail has high strength, good compatibility with tissue, and low rejection, and is a medical material more commonly used in clinical orthopedic surgery. Once the titanium nail and the flesh grow together, there is generally not much impact, and the titanium nail can be removed by cutting through the relevant tissue or muscle. For young people, it is recommended to remove the titanium nail, because after all, the titanium nail is a foreign body, to avoid the corresponding adverse consequences in the future. However, for the elderly and frail patients who cannot tolerate a second surgery, they can be observed without removal and further treatment can be decided depending on the patient’s condition. If the patient has clinical symptoms, the titanium nail can be surgically removed if necessary; if the patient has no clinical symptoms, it can be left alone.
