The main sequelae of comminuted femoral fractures are as follows: The first is a delay in healing and nonunion of the fracture ends. Due to the comminuted nature of the fracture, local blood circulation has been damaged, and even with surgery, it is difficult to restore circulation. This can lead to delayed healing and nonunion of the fracture ends, generally requiring observation for around one year. If fracture lines are still clearly visible after a year, this confirms a nonunion, necessitating further surgery and bone grafting to restore the healing of the fracture. The second, in cases of nonunion, is the possibility of plate fracture. Many patients, unable to endure extended bed rest, need to start weight-bearing walking. If the fracture ends have not healed and weight-bearing occurs, the body's full weight concentrates on the plate, leading to stress fractures of the plate and screws. Should such stress fractures occur, immediate surgical intervention is needed to replace the internal fixation.
