The regular healing time for a broken bone is around six weeks to three months, which is the standard time for adults. It can vary depending on the type of fracture and the age of the patient, for example, it only takes four to six weeks for a femoral stem fracture in an infant to reach bony healing, whereas it takes six months for a femoral stem fracture in an adult to heal. There is also a clear correlation to the type of fracture, with comminuted fractures taking longer to heal and simple fractures taking relatively less time to heal. In addition, the blood supply to the fracture site is one of the most important reasons for healing. If the blood supply to the fracture site is good, the fracture will heal faster, if the blood supply to the fracture healing site is poor, it may lead to delayed healing or even non-healing, of course, the surgical method and the conservative treatment also have a certain effect on the healing of the fracture.
