6-8 weeks: Depends on several factors including the location, patient's age, smoking, and others.

It depends.: Most fractures take between 6 to 8 weeks to heal. They may be healed enough to allow for movement much sooner, however, and may continue to remodel for months after healing has occurred. Other factors may include the type of fracture, the form of treatment chosen, and patient factors such as age.
