Tibial intramedullary nails usually loosen and cause localized pain, or symptoms of rattling during movement. Intramedullary nailing is an orthopedic internal fixation device used to immobilize the fracture site and prevent redisplacement of the fracture site, as well as to reduce the incidence of surgical infections by using closed minimally invasive surgery. In addition, the use of intramedullary nailing fixation is generally more secure, and functional exercises and weight bearing can be performed at an early stage. However, the specific exercise and weight-bearing time should be decided by the professional doctor according to the patient’s individual situation, do not exercise and weight-bearing too early, so as not to cause loosening of the internal fixation. When the tibial intramedullary nail loosens, local pain may occur, joint stability may also be affected, and abnormal noise may occur during activities. If you suspect that the intramedullary nail has loosened, you should inform your doctor in time and take appropriate measures.
